1. INTRODUCTION
I.I. PURPOSE
The purpose of this appendix is to document the hydrology & hydraulic analyses completed in support of the Murrieta Creek Flood Control and Environmental Restoration Project in Riverside County, California (see Figure 1: Project Location Map). This design is based on the Locally - Preferred Recommended Plan selected in the Feasibility Report (Ref. 1).
1.2. DESCRIPTION OF STUDY AREA
The study area is located in Riverside County, California and covers the Santa Margarita River watershed. It extends from the unincorporated area of Wildomar, through the cities of Murrieta and Temecula to the confluence with Temecula Creek. Murrieta Creek is a major tributary to the Santa Margarita River. The project is a multi -purpose flood control, environmental restoration and recreation project along approximately 7.1 miles of Murrieta Creek. The major project features include channel widening and deepening; an environmental corridor along the length of the project; a multi -purpose detention basin; a wetland restoration area; a recreation park and three bridge replacements. The project is divided into four construction phases: Phase 1 from approximately the USGS gauging station at the downstream end to downstream of First Street; Phase 2 beginning around First Street and extending to the confluence with Santa Gertudis Creek; Phase 3 from the confluence to Elm Street; and Phase 4 encompassing Elm Street to Tenaja Road. Phase 1 is the only reach that has been constructed, with the exception of the downstream end of the project, denoted as Phase IA. Phase 2 is defined to extend just upstream of the Winchester Road bridge to approximately 800 ft downstream of the First Street bridge, from River Station 189+00 to River Station 59+00, respectively. Refer to Figure 1 for location of project Phases.
2. HYDROLOGY
2.1. INITIAL DESIGN AND HYDROLOGY OF ORIGINAL PROJECT
The level of protection for the project was analyzed in the Feasibility Report (Ref. 1). The primary objective of the hydrologic analysis was to determine the Existing and Future With- and Without -Project discharge for a range of return periods, including 2-, 5-, 10-, 25-, 50-, 100-, 200- , and 500-yr (0.50, 0.20, 0.10, 0.04, 0.02, 0.01, 0.005 and 0.002 expected Annual Exceedance Probabilities {AEP}) event. The Hydrology Appendix in the Feasibility Report includes the following information for the Murrieta Creek Watershed: climatic and hydrologic characteristics; discharge -frequency data for Existing and Future With- and Without -Project Conditions; volume -frequency data; and a summary of the hydrologic modeling process. For a detailed description of the methodologies and assumptions used in the analysis refer to the Feasibility Report. Refer to Table 1 for With -Project discharges and Figure 2 for the adopted discharge - frequency curve. The design of the project is to provide a minimum level of flood protection to local resident equivalent to control the 1% Annual Chance Exceedance (ACE) event with a 95% confidence of containment.
1 3. HYDRAULIC ANALYSIS AND DESIGN
3.1. GENERAL CONSIDERATIONS
The hydraulic design of the channel for construction of Phase 2 of the Murrieta Creek project is based on applicable U.S. Army Corps of Engineers guidance, as well as guidance provided in other technical references on applied hydraulics engineering. A list of the references used is included in section 7.
3.2. EXISTING CHANNEL
The existing channel for Murrieta Creek within Phase 2 has natural invert and side slopes. There is significant vegetation along the banks and along the invert of the creek. Phase 2 is defined to extend just upstream of the Winchester Road bridge to approximately 800 ft downstream of the First Street bridge, from River Station 189+00 to River Station 59+00, respectively. Phase 2 is bounded by the natural channel of Phase 3 near Winchester Road at the upstream end and constructed Phase 1 near First Street at the downstream end.
3.3. CHANNEL MODIFICATIONS
The channel modifications were originally designed to convey a design discharge of 23,200 ft3/s (Ref. 1). However, the need to incorporate some relatively minor design revisions, as discussed in the Channel Design Criteria and Procedures section, required the design discharge to be reduced to 22,300 ft3/s to avoid increasing the size of the channel downstream of Phase 3. The detention basin in Phase 3 will be sized appropriately to maximum outflow of 22,300 ft3/s. The channel modifications for Phase 2 extends from River Station 189+00 to River Station 59+00 (upstream end of constructed Phase 1). Throughout this reach the channel will be widened by excavation to provide a trapezoidal cross section. The excavation will provide a design invert slope of 0.002 from River Station 189+00 to 83+00, flattening to 0.0015 from River Station 83+00 to 61+00, and 0.0035 from River Station 60+00 to 59+00. The design bottom width will range from 140 ft to 363.6 ft throughout Phase 2. Downstream of the First Street bridge, the channel bottom widens to tie in with the width of constructed Phase 1. Side slopes will be landscaped except for the Old Town Temecula reach, which will be soil cement.
Specific ecosystem restoration measures for Murrieta Creek focused on alternatives that would provide greater extent and/or quality of in -channel riparian and peripheral channel habitat. As such, a larger vegetated corridor was allowable in Phase 2. The unmaintained vegetation is a 2 ft high riparian terrace that will be allowed to grow across approximately 20 ft to 150 ft of the channel bottom extending outward from the toe of the left side slope for the entire reach of construction. The vegetation in the remaining invert will be subject to annual mowing and periodic sediment removal. Maintenance of the side slopes of the channel is not scheduled but will be performed as necessary and in the event of an emergency. The channel bottom widths through Phase 2 are provided in Table 2.
0)
The channel depths of the channel will vary from 15.7 ft to 25.7 ft along Phase 2. The side slopes will be typically 2 horizontal to 1 vertical (2H:1 V) or 3H:1 V, with the exception of the reach through and downstream of Old Town Temecula, where near -vertical walls of 1H:4V were incorporated because of right-of-way limitations, and at the downstream end where Phase 2 ties into constructed Phase 1. The design channel depths and side slopes through Phase 2 are provided in Table 3.
To eliminate the potential for upstream headcutting, a grouted stone grade stabilizer will be located approximately 300 ft upstream of the Rancho California Road bridge. The stabilizer will be 20 ft in length and extend to the whole channel width, with grouted riprap provided for slope protection.
3.4. DESIGN DEPARTURES FROM RECOMMENDED PLAN
A preliminary design for the recommend plan project was prepared in the Feasibility Study (Ref. 1). However, detailed design studies prepared since the completion of the feasibility report have revealed the need for several design departures from the recommended plan. These departures are necessitated by several constraints involving difficult excavation, interference with major utilities, and right-of-way limitations.
In Phase 2 the design invert slope was flattened from 0.002 to 0.0015 just upstream of the Main Street bridge to the downstream end of the reach. The slope was flattened to match the reduced slope for constructed Phase 1.
The original side slopes were changed from gabions to a vegetative corridor to improve the project aesthetics. As discussed above, the vegetation will be allowed to grow unmaintained across 20 to 150 ft of the channel bottom extending outward from the toe of the left side slope for the entire reach of construction.
The side slopes through Old Town Temecula were steepened from 3H:1V to 1HAV (0.25H:IV) because of right-of-way constraints. The side slope construction material was also changed from gabions to soil cement.
At the upstream end of the constructed Phase 1 the channel bottom width was increased to take advantage of wider available right-of-way, thereby providing an increased width of riparian habitat. To accommodate this widening, the downstream end of Phase 2 from Station 65+50 to 59+00 was also widened.
The width of the service road and equestrian trail was increased to 15 ft. The service road will be along both sides of the channel, where the right bank service road will be shared usage for an equestrian route. Maintenance road access ramps were incorporated after the 90% submittal.
There will be five access ramps along Phase 2. The width of the concrete access ramp is 15 ft along the top and slopes down at a 10% gradient.
Paved undercrossings beneath bridges on both sides of the channel will be used for maintenance and provide connectivity for trails that ensure adequate safety for pedestrians/riders by enabling 3 them to cross these roads without interfering with traffic on busy arterial routes. Design criteria adhere's to HH Policy Memorandum Number 3 Hydraulic Design and Criteria for Underpasses and Access Ramps (Ref. 2) A minimum clearance of 14 ft is provided at all bridge undercrossings.
Appropriate design values for Manning's roughness coefficient "n" were evaluated in detail for the feasibility study. However, subsequent discussions with the RCFC&WCD on vegetation planting and maintenance required refinement to the roughness values. A new analysis to determine roughness values was performed in May 2007. Refer to Section 4.3 for selection of roughness coefficients.
The original unmaintained environmental corridor consisted of a two tier 2 ft high riparian terrace. However, the upper terrace in constructed Phase 1 was not able to receive adequate amounts of water to support restoration efforts. Therefore, the decision was made to delete the upper riparian terrace from the Phase 2 and Phase 4 design. The Environmental Resources Branch, their contractor and RCFC&WCD were in agreement that it would not affect environmental mitigation requirements along Murrieta Creek. In a subsequent meeting the decision was made to delete the lower terrace in order to accommodate a wider unmaintained width (10 ft wider) at the upstream end from River Sta. 185+00 to 180+00. This was done per request of the resource agencies to find areas where the project could have more unmaintained area without diminishing the project's flood control intent.
The drop structure near Rancho California Road bridge was modified to a grade stabilizer. The design invert elevation was lowered by approximately 2.7 ft from River Station 113+00 to the upstream end to decrease the potential for headcutting.
4. CHANNEL DESIGN CRITERIA AND PROCEDURES
4.1. GENERAL CONSIDERATIONS
Water surface profile computations for the design discharge were prepared with the U.S. Army Corps of Engineers (USACE) Hydrological Engineering Center's River Analysis System (HEC- RAS) computer program, version 4.1 (Ref. 3). The full design discharge of 23,200 ft3/s for the subject reach was initially carried over from the feasibility study, but was later reduced slightly, as discussed below. The need to incorporate some relatively minor design revisions required the design discharge to be reduced to 22,300 ft3/s to avoid increasing the size of the channel. Design studies to optimize the size of the upstream detention basin are pending (Phase 3). The design discharge was reduced to 22,300 ft3/s, which is maximum design ouflow from the detention basin. The water surface profile computations were started at River Station 28+75, which is about 100 ft downstream of the USGS gauging station. The hydraulic model calibration is provided in the Feasibility Report (Ref. 1) Hydraulic analysis indicates that flows do not pass through critical depth in the vicinity of the gauge; therefore, the starting water surface elevation was set to a normal depth slope of 0.002. The top of bank or top of levee elevations were set to be a minimum of 3 ft above the computed water surface profile for the design discharge. The performance and reliability of the project design was assessed with a risk -based analysis as described in Section 5.

4.2. MAPPING
Eagle Aerial completed topography, by photogrammetric method, of the Murrieta Creek site in 2002. All elevations are based on North American Vertical Datum of 1988 (NAVD88) and all horizontal distances are based on North American Datum of 1983 (NAD83). The topography was developed using State Plane coordinates California Zone VI.
4.3. ROUGHNESS COEFFICIENTS
The roughness coefficients for the channel bed and side slopes were estimated in the Feasibility Study. Since the roughness coefficients is highly variable and depends on a number of factors, a range including a minimum, normal, and maximum value is typically provided for a given channel condition. The minimum and maximum values would be utilized to estimate the maximum velocity and depth, respectively, within the channel. Thus, the velocity and capacity conditions refer to the minimum and maximum values, respectively, of the roughness coefficient for a given condition. The normal value is approximately the mean of the minimum and maximum, and it corresponds to the best -estimate (most likely) roughness coefficient and was used to compute the anticipated depth and velocity within the channel. The roughness coefficients for the channel bed and side slopes are provided in Table 2 of the Hydraulics Appendix in the Feasibility Study. A brief summary is provided below.
For Phase 2 the maintained portion of the channel invert will be subject to annual mowing and sediment removal. Specifically, the maintenance would entail annual mowing and sediment removal when deemed necessary, of 75% of the channel invert, with the remaining 25% allowed for vegetation to mature, but constrained by the deposition of no more than 3 ft of sediment.
Without such maintenance, the future with -project condition would induce a higher water surface profile and corresponding 100-yr floodplain. The best -estimate of the roughness coefficients for the annually mowed bed section, fully mature vegetation along the riparian terrace and vegetated side slopes are 0.027, 0.07, and 0.095, respectively. In the mowed section, the roughness coefficients are based on 6-in high vegetation and selected from Chow's Open Channel Hydraulics (Ref. 4). For the fully mature vegetation section, the best -estimated roughness coefficient was estimated using a combination of Cowan's vegetation classification (Ref. 5) and Chow. It also reflects a condition where half of the vegetated region having a roughness coefficient of 0.12 is washed out. The roughness coefficient for the vegetative side slopes were based on field and/or from the 1994 orthophotos using the Cowan's Method (Ref. 5).
The roughness coefficients for the channel invert of 0.07 for the unmaintained riparian corridor and 0.027 for the maintained section are still appropriate. However, subsequent discussions with the RCFC&WCD on vegetation planting and maintenance required additional refinement to the roughness values along the side slopes. On 22 March 2007, a meeting was held to determine an acceptable roughness coefficient value for the vegetation that will likely develop on the channel side slopes along Phase 2. Based on the meeting, no woody vegetation such as trees would be planted along the side slopes. The RCFC&WCD's normal annual maintenance operations will prevent large woody vegetation from becoming established. As such, the RCFC&WCD crews will conduct regular inspections to ensure that invasive species do not become established and 5 will remove all obvious or conspicuous trees from the side slopes. In addition, large shrubs will be maintained by means of chopping, sawing, or similar method to a 3-4 ft height. Therefore, a new analysis to determine roughness values along the channel side slopes was performed. Table 4 documents the results of the analysis for Phase 2 and the paragraphs that follow describe the selection of the roughness coefficients.
Phase 2 2H:1 V Side Slopes (River Station 189+00 to 183+00) The existing concrete side slopes downstream of the Winchester Road Bridge will be removed and replaced with grouted stone. The roughness coefficient for the entire side slope was set to
0.025.
Phase 2 3H:1 V Side Slopes (River Station 183+00 to 98+00) Based on the typical planting scheme for Phase 2, upland species will cover about 65% of the total side slope, while the remaining 35% will be riparian/transition species. Therefore, a subdivision between the two zones (Al and A2) was required. Refer to Figure 2 for typical cross section subdivisions. Each zone was further divided by plant species and then grouped by plant type (i.e. tree, shrub, forb, grass).
The mean of the maximum vegetation height by plant type from each zone was also determined.
In the lower area (zone Al), the average maximum height of the shrubs is 3-4 ft and 3.2 ft for the forbs. For the upper area (zone A2), the average maximum height for the shrubs, forbs and grass is calculated to be 3.6 ft, 0.5 ft and 1.1 ft, respectively.
The average Phase 2 maximum average depth of flow is computed to be 14.5 ft for the design discharge (22,300 ft3/s). As a result, vegetation in zone Al was fully submerged while approximately 8.2 ft of zone A2 was inundated during a 1 % ACE. Accordingly, the local average peak flow depth of flow in zones A2 and Al is 4.1 ft and 11.3 ft, respectfully.
The roughness coefficient using Cowen's Method for the velocity and capacity conditions were estimated for the vegetation after it has fully matured by applying the adjustment factors as indicated in the U.S. Geological Survey (USGS) Water -Supply Paper 2339, Guide for Selecting Manning's Roughness Coefficients for Natural Channels and Flood Plains, 1989 (Ref. 5). Since the roughness coefficient is highly variable and depends on a number of factors, a range including a minimum, normal, and maximum value is typically provided for a given channel condition. The minimum and maximum values are utilized to estimate the maximum velocity and depth, respectively, within a channel. Thus, the velocity and capacity conditions referred to as the minimum and maximum values, respectively, of the roughness coefficient is for a given condition. The normal value is approximately the mean of the minimum and maximum, and corresponds to the best -estimated (most likely) roughness coefficient.
The Manning's roughness adjustment value t for the total side slope was calculated by taking into consideration the two zones of vegetation. The best -estimated adjustment values for both the shrubs and forbs in zone Al is the average between 0.01 and 0.025, or 0.018. This corresponds to the USGS Paper classification in general as "amount of vegetation — medium," no
and in particular to "moderately dense stemmy grass, weeds, or tree seedlings growing where the average depth of flow is from two to three times the height of the vegetation." The best -estimated adjustment value for zone A2 was also separated by plant type. The adjustment value determined for the shrubs in this zone is classified in general as "amount of vegetation — large," and in particular to "turf grass growing where the average depth of flow is about equal to the height of the vegetation," where the average value for the adjustment value is between 0.025 and 0.050, or 0.038. The best -estimate for the forbs and grass averages between
0.01 and 0.025, or 0.018, is classified in general as "amount of vegetation — medium," and in particular to "brushy, moderately dense vegetation growing along the banks and no significant vegetation is evident along the channel bottoms."
The adjustment value best -estimated condition for zones Al and A2 was then calculated using a single length -weighted average. The USGS paper classification for the amount of vegetation adjustment factor for the side slopes is 0.018 for zone Al and 0.035 for zone A2.
Finally, the determination of an adjustment value was calculated for the total side slope conveyance. Conveyance of flow was subdivided into vertical subsections along the vegetated side slopes. The computed adjustment value is 0.020.
The base n value for the channel side slope corresponds to a relatively uniform and smooth earth surface, similar to a plane bed on the channel bottom. A roughness coefficient of 0.022 was adopted as the best -estimate base n value for the channel side slopes.
The composite roughness value for the side slopes is the sum of the base n value and the total adjustment value. Therefore, the best -estimated condition for roughness value for the 2H:1 V side slopes along this reach of Phase 2 is 0.042 (0.020 + 0.022).
Phase 2 1HAV Side Slopes (River Station 98+00 to 65+50) and 1H:2V Side Slopes (65+50 to 59+00
The roughness coefficient for the entire side slope near -vertical walls (1HAV) throughout the Old Town Temecula area was set to 0.023 for soil cement.
Sensitivity Analysis
A separate "n" value analysis was conducted to determine the sensitivity of n value selection.
The analysis utilized a roughness value of 0.025 for the entire Phase 2 channel. The results from changing the values were compared to the values as stated above. The results are shown in Table
5. The results of utilizing the roughness value of 0.025 are denoted as "adjusted n values" in the table.
The results are very similar, however, the adjusted results for average flow velocity was slightly higher. The higher velocities were used to determine appropriate riprap thickness to protect bridge piers from potential scour.
7 4.4. SEDIMENTATION ANALYSIS
A one dimensional sediment transport analysis was performed by MAHR Works in 2007 (Ref. 6, and Exhibit A of this report) using the Sedimentation in Stream Networks program, HEC-6T (Ref. 7). The sediment transport model extends from Slaughter Canyon to the USGS Stream Gage Station, downstream of First Street. The model network consists of Murrieta Creek and the Warm Spring and Santa Gertrudis tributaries. Secondary flow sources of Carter Canyon and Long Canyon, as well as project features (detention basin, channelization, new vegetation), and bridges are also accounted for in the analysis. Overall, the models were stable, and the results were generally as expected. Phase 2 showed a general trend of degradation. A detailed discussion can be found in the 2007 analysis report in Exhibit A.
In 2008, two detention basin alternatives were analyzed using HEC-6T: Alternative 1 consists of full ecosystem restoration, i.e. constructing islands within the basin and a fully vegetated bottom; and Alternative 2 consists of no islands within the basin but with a fully vegetated bottom (for more capacity). The original 2007 HEC-6T model was used and revised to include the components of Alternative 1 and 2. The results from this analysis show that for both Alternatives the general trend is degradation (up to 4.3 ft with Alternative 1 and 3.8 ft with Alternative 2) throughout Phase 2; with the exception of the downstream end of Phase 2 which shows aggregation (up to 4.7 ft with Alternative 1 and 4.5 ft with Alternative 2) at the peak flow.
Refer to Exhibit B for output HEC-6T results. Aggregation values were retained from Alternative 2 and added on top of the design invert using the "Fixed Sediment Elevations" tool in HEC-RAS. Aggregation results were incorporated to determine appropriate top of channel bank elevations.
A long term sediment analysis using HEC-6T was performed in 2012. The original 2007 HEC- 6T model was used and was modified to include measured daily mean discharges since 1974.
Daily mean discharges were extracted from the U.S. Geological Survey gage no. 11043000.
Records following construction of the Skinner Reservoir were used in the analysis, 1974 to 2011.
Results show up to 6.6 ft of general degradation in Phase 2. This area (from River Station 189+00 to 180+00) will require a toe down depth to 7 ft while the remainder of the channel will require 5 ft of toe down (River Station 180+00 to 59+00). Refer to Exhibit C for results. The largest degradation is at the upstream end of Phase 2 and decreases downstream. A temporary grouted stone drop structure will be constructed at the upstream end of Phase 2. The structure will be 20 ft in length and extend to the whole channel width, to a depth of approximately 7 ft.
In this area flow velocities are high due to the drop which causes the flow to pass critical depth in order to balance the water surface profile equation. An apron will be provided on the downstream side of the drop structure. The required length of the apron as defined in the USACE Hydraulic Design Criteria (Ref. 8) by the following equation and will be a minimum of
33.2 ft.
LB = CL hd,
Where d50 = particle size for which 50% is finer by weight, ft LB = length of basin, ft
N.
CL = empirical apron length coefficient
h = height of drop
d, = critical depth over crest
Bridge pier protection will be constructed at bridge piers, which will eliminate the potential for scour. There are 5 bridges along Phase 2, all of which have piers except for Main Street. The bridge abutments will not be subject to the active flow of the design discharge. To determine the required size of stone for riprap at bridge piers, the Federal Highway Administration's (FHWA's) Hydraulic Engineering Circular No. 23 (Ref. 9) was used which recommends using the rearranged Isbach equation:
d50 =
0.692(Vdes )2
(Sg -1)2g
Where d50 = particle size for which 50% is finer by weight, ft Vd, = design velocity for local conditions a the pier, ft/s Sg = specific gravity of riprap (usually taken as 2.65) g = acceleration due to gravity (32.2 ft/s)
If the cross-section or channel average velocity, Vavg, is used, then it must be multiplied by factors that are a function of the shape of the pier and its location in the channel.
Vd,, = KI K2 Va„g
Where K,= shape factor equal to 1.5 for round -nose piers K2 = velocity adjustment factor for location in the channel (ranges from 0.9 for a pier near the bank in a straight reach, to 1.7 for a pier located in the main current of flow around a sharp bend). An average value of 1.3 was used in this design.
Va„g = channel average velocity at the bridge, ft/s
The thickness of the riprap was determined using FHWA's No. 23 (Ref. 9). The minimum riprap thickness (t) is 3d50. To determine the upstream and downstream extent of riprap placement, the placement is 2 times the width of pier. Pier protection details are provided in Table 6.
4.5. CHANNEL DESIGN DATA
The minimum bank elevation was set at 3 ft above the computed water surface elevation for the design discharge. The HEC-RAS Output data is provided in Table 7. Note that the column titled "Min Ch El" represents the invert elevation plus sediment deposition results from the 2008 HEC- 6T results. The standard output table was modified to include a column entitled "Min Ch El w/o 9 Sed," which provides invert elevations without the added sediment feature. The 1% ACE water surface profile is provided in Figure 4. Typical cross sections are provided in Figures 5 and 6.
4.6. SIDE SLOPE REVETMENT
The majority of the channel side slopes will have buried riprap with the exception of two areas.
The first exception is through the highly constricted Old Town Temecula area where side slopes would not support growth of vegetation. The construction material for the near -vertical walls through this area will be soil cement. The other area is at the upstream end of Phase 2 where existing concrete side slopes will be replaced with grouted stone.
The program ChanlPro version 2.0 (Ref. 10) was used to determine appropriate stone size. The phase 2 area between River Stations 189+00 to 98+00 were divided into three sections based on similar side slope configuration or between bridges. The three sections are from River Sta. 189+00 to 169+00 (2H:1 V side slopes); from River Sta. 169+00 to Rancho California Rd. bridge; and from Rancho California Rd. bridge to River Sta. 98+00 (3H:1 V side slopes).
ChanlPro input parameters for the three sections are provided in Table 8. The calculated D50 and D100 for all three sections is 6-in and 9-in, respectively. However, Los Angeles District policy requires a thickness layer no less than 12-in (Ref. 11). In USACE EM 1110-2-1601 Hydraulic Design of Flood Control Channels (Ref. 12), the riprap thickness is defined as 1D100, therefore, the minimum thickness is 12-in. The thickness and stone size was increased to 15-in to match what was already placed in constructed Phase 1. In Phase 2 riprap will extend to match the height of the existing riprap constructed in Phase 1.
Toe down depth was determined from the 2008 alternative sediment analysis and 2012 long term sediment analysis (refer to section 4.4). Based on the 2008 and 2012 analyses the deepest scour depth was 4.3 ft and 4.9 ft, respectively, below river station 179+00 to the end of Phase 2. The toe down depth was set to 5 ft from 180+00 to 59+00. Toe -down was set to 7 ft from 180+00 to 189+00 since the long term sediment analysis showed up to 6.4 ft of scour.
Riprap will be placed on the lower half of the channel banks. In order to reduce construction costs, the upper half of the sideslopes will be reinforced with a Turf Reinforcement Mat. For the purposes of this analysis, Propex Pyramat® was used for the design, but an equivalent turf reinforcement mat can also be used provided it has similar properties. Pyramat will be used in conjuction with topsoil and seeding to achieve the vegetated performance state.
The design parameters for using Propex Pyramat are listed in the Manufacturer's product specifications. These parameters include: Tensile Strength, UV Resistance, Max Flow Velocities, and Max Shear Stress.
ERDC's report on "Stability Thresholds and Performance Standards for Flexible Lining Materials in Channel and Slope Restoration Applications" under the Ecosystem Management and Restoration Research Program (EMRRP) describes the design criteria (Ref. 19). Tensile Strength should conform to ASTM D-6818 and have a minimum value of 3,000 x 3,000 lb/ft2 for High Performance Turf Reinforcement Mats (HPTRM). Pyramat meets ASTM D-6818 and has a Tensile Strength of 4,000 x 3,000 lb/ft2 which is adequate. Under ASTM D-4355 testing method, UV Resistance for Pyramat is 90% Tensile Strength retained @ 6000 hours. This translates to an estimated product design life of over 50 years. In the vegetated performance state for Pyramat, 10 the channel's velocity cannot exceed 25 ft/sec and shear stress cannot exceed 15 lb/ft2. Using HEC-RAS output tables, maximum velocity and shear stress for the channel were calculated to be 10.44 ft/s and 3.72 lb/ft2,respectively. Therefore, the selection of Pyramat as the method of side slope revetment was determined to be adequate.
5. PROJECT PERFORMANCE RELIABILITY ANALYSIS
The section below is based on Phase 3 detention basin Alternative 2. Refer to Sedimentation Analysis section above for description of basin Alternative 2.
5.1. OBJECTIVE OF RISK -BASED ANALYSIS
The USACE process for the Federal Emergency Management Agency (FEMA) National Flood Insurance Program (NFIP) system evaluation is described in Engineering Circular (EC) 1110-2- 6067 (Ref. 13). The USACE probability of exceedance and uncertainty analysis procedure for proposed flood damage reduction plans is described in Chapters 4 and 5 of Engineering Manual (EM) 1110-2-1619, Risk -Based Analysis for Flood Damage Reduction Studies (Ref. 14). For the Phase 2 incised channel the analysis will include the uncertainty in the discharge -probability function and in the stage -discharge function. A Monte Carlo simulation in the USACE's Hydrologic Engineering Center's Flood Damage Analysis (HEC-FDA) program version 1.2.5 (Ref. 15) was used to compute the uncertainty and assurance [conditional non exceedance probability (CNP)] of the incised channel to reduce the flood risks from the 1 % ACE (design discharge) (Refs. 13 and 15). Essentially, this means that the incised channel must have a "conditional non-exceedance probability" (performance reliability) of 95%, with a minimum of 2 ft of freeboard added to the computed water surface elevation using the median estimate of the 1% ACE. Assurance between 90 and 95% can be found in accordance with NFIP system evaluation requirements if it is at least the FEMA required freeboard above the 1 % ACE.
Assurance less than 90% cannot be found in accordance with NFIP levee requirements (Ref. 13).
The risk -based analysis was performed as described below.
5.2. COMPUTATIONAL METHODOLOGY PROCESS
Following the guidance found in EM 1110-2-1619 (Ref. 14) and HEC-FDA User's Manual (Ref. 15), the computational methodology for the risk -based analysis requires a two-part process to determine the necessary input information into the HEC-FDA program. The first part is to compute the "Stage Uncertainty," and the second part is to determine "HEC-FDA Reliability Analysis." A discussion of its development is as follows:
5.2.1. Part One: Stage Uncertainty
Total stage uncertainty is a function of natural uncertainty Natural) and model uncertainty (Smodel)•
Natural uncertainty is a function of four parameters; watercourse bed composition, drainage area, 1 % ACE flow, and stage range.
11 Watercourse Bed Composition (Bed Identifiers With respect to the watercourse bed composition factor, information in "Table 5-l" was utilized (Ref. 14). Refer to Table 9 in this report for the values. A higher value relates to higher "mobility" of the bed material. (Note this is completely independent of the smoothness of the bed material). Manning's n variation is a function of Smodel (as will be discussed later.) For the bed material, consider how confident one can be that the bottom topography will remain unchanged over time. A less "mobile" material will resist scour and erosion better. Since the evaluation reach invert is comprised of sands, the bed composition factor corresponds to 4.
Drainage Area. As discussed in the Feasibility Report (Ref. 1), the contributing drainage at the Phase 2 location is 222 square miles.
The 1 % ACE (100-yr return period) Event. Through the evaluation reach, the 1% ACE peak discharge used for the analysis is 22,300 ft3/s.
Stage Range. Range is defined as the maximum predicted or observed range of stage on the watercourse. The minimum flow in the river is set to zero, therefore, the minimum water surface elevation is equal to the invert elevation at any location. In a theoretical worst case scenario, the water surface could rise to the height of the bank and then by some additional surcharge value while overflowing. For this evaluation, the height of the bank plus one foot was determined to be the maximum water surface elevation at any given cross section river station since the river is essentially ephemeral with no flow for much of the year.
The four parameters listed above serve as inputs for the equation below, which yields natural uncertainty. As explained in Ref. 14, this equation is written to use metric units of measure and therefore requires conversion before calculating.
Stnaturaz - L 0.07208 + 0.04936 Ibed - 2.2626 x 10-7 Abasin +
0.02164 Hrange + 1.4194 x 10-5 Q, oo ] 2
Where Ibed = streambed identifier for the size of the bed material which controls flow in the reach of interest
Abash = drainage basin area in square kilometers
H,.a,,ge = maximum expected or observed range in stage in meters Qroo = peak discharge of the (1% ACE) flood in cubic meters per second Since an HEC-RAS model was available for the evaluation reach, invert and bank elevation data can be found in tabular form for each designated cross section. With this information, a Snat,,,al value was determined for each cross section. The hydrologic, hydraulic and natural uncertainty data are displayed in tabular format in Table 10: Computation of Uncertainty of Stage -Discharge Relationships.
5.2.1.1 Model Uncertainty (Smode) from Computer Model Data. As defined in EM 1110-2- 1619 (Ref. 14), model uncertainty is associated with the accuracy of the Manning's n-values 12 used in the model of the watercourse. Because the n-value is not a measurable quantity, there is some inherent uncertainty with the n-values used in a computer model or a mathematical calculation.
As mentioned, the Manning's n-value determination is not exact. This is demonstrated in the information presented in Figure 7 (Ref. 14, Figure 5-4), which plots n value standard deviation versus average of n values estimates. This figure provides information on a representative plus or minus range for any assumed n-values. i.e.; if the n value assigned is 0.042, the selected value is determined to be within 0.014 of that value, or between 0.028 and 0.056.
To calculate the model uncertainty, two modified geometries for the evaluation reach were created in HEC-RAS (Ref. 3); one with a lower range (assumed n minus uncertainty from Figure 5) and one with an upper range (assumed n plus uncertainty from Figure 7) of n-values. In addition to modifying Manning's n-values, debris parameters were adjusted in the HEC-RAS model to create a best and worst case scenario. For this study, the "best case" geometry with low n values was modeled with the debris option not factored in (i.e. turned off in the model). Debris for the high n-value geometry was set at two feet on each side of piers, stretching from the river bed to the waterline. This created what's referred to as "worst case" geometry.
The value of model uncertainty is the standard deviation of the variation in water surface elevations between the "best case" and "worst case" geometries. This being the case, a steady state analysis was conducted for each geometry using HEC-RAS. The output results from both iterations were then displayed on a spreadsheet with a focus on determining the water surface elevation at each cross section within the evaluation reach. Finally, in accordance with Ref. 14, these water surface values were averaged to determine an E111ean for each damage sub -reach. The sub -reaches used for this analysis are Phase 1 and Phase 2. The deviation in the water surface profiles were then calculated using Eqn. 5-7 (Ref. 14) below.
Emean
Smoder = 4
Where Emean = mean difference between the upper and lower limits of the calculated stage For this assessment, model uncertainty was averaged over each damage sub -reach.
5.2.1.2 Total Uncertainty (Stotal). Model and natural uncertainty are related using the Eqn. 5-6 (Ref. 14) to calculate the total uncertainty at the damage reach's cross -sections stations. The natural uncertainty for the reach was averaged with the average model uncertainty for the encompassing reach to calculate the total uncertainty. The index location for the evaluation reach is specified to aggregate stage -damage functions with uncertainty for flood damage analysis calculations. For this analysis the index location was set at the cross section location with the least freeboard for the 1 % ACE to ensure the reach meets the minimum freeboard criteria.

St = natural + model
13 Where St = total standard deviation of uncertainty
snatural = standard deviation of uncertainty as a function of pertinent natural physical characteristics of the watershed and conveyance
Smoaer = standard deviation of uncertainty of computed water surface data using mathematical models
The total uncertainty calculation for this analysis is summarized in Table 10.
5.2.2. Part Two: HEC-FDA Reliability Analysis
5.2.2.1 Step One - Configure (Damage Reaches and Index Stations).
Defining Damage Reaches. The evaluation reach includes the limits of Phase 2.
Selecting Sub -Reach Index Stations. HEC-FDA (Ref. 15) evaluates the reliability of an entire damage reach based on the reliability at one index station within the sub -reach. However, for this project there is only one reach. Information on the reach index location parameters is shown in Table 10.
5.2.2.2 Step Two - Hydraulic Data (Water Surface Profile, Stage -Discharge, Exceedance Probability).
Water Surface Profile Data. The reliability analysis is based on the 1 % ACE event and associated water surface elevations. The HEC-FDA analysis requires more information; specifically, water surface profiles for eight different frequency flow events. The normal default events are the 2-, 5-, 10-, 25-, 50-, 100-, 250-, and 500-year events. These defaults were changed based on available information. This analysis utilized the 200-year event instead of the 250-year event which was developed in the Feasibility Report (Ref. 1), refer to Table 1 for Discharge - Frequency Results. Once all eight flow regimes were established, they were each used to complete a steady state analysis with the base project geometry in HEC-RAS. Appendix C of the HEC-RAS User's Manual (Ref. 3) describes in detail how to export the water surface profiles from the HEC-RAS model into the HEC-FDA program.
Stage Dischar-ae Function with Uncertainty. Defining the uncertainty about each water surface profile across the different frequency flow events was required. Once the water surface profiles are established, the HEC-FDA program then retrieves a stage -discharge function from the water surface profile. Subsequently, the uncertainty then needs to be assigned for each index location.
The HEC-FDA software will calculate the uncertainty based off a normal distribution and an error and stage input by the user. The uncertainty calculated at each index location is calculated and then applied along with the corresponding 1 % ACE water surface elevation at the given index location. The normal distribution assumes that uncertainty will not be higher than the user -entered value, and this analysis also assumes that the uncertainty will reduce linearly to zero as flow reduces to zero.
14 Exceedance Probability Function with Uncertainty. The basic information for this task is to import the water surface profiles from HEC-RAS to HEC-FDA. The graphical determination option was used in the analysis to define the uncertainty in the discharge exceedance probability relationship. This approach requires a value in years for the equivalent record length. The discharge -frequency data was based on an equivalent streamgage record length of 92 years.
Crest Elevation Data: Top of bank elevations for the index location was inputted into HEC- FDA using the levee data option.
5.2.2.3 Step Three — Reliability Analysis.
With the above information as input into HEC-FDA program, an "Evaluation by Analysis Years" was performed on the evaluation reach. The results of this analysis, which specify the CNP for the specified frequency events, indicated that the evaluation reach has a 92% non-exceedance probability for the 1 % ACE with over 3 feet of freeboard. These results for the 1 % ACE are summarized in Table 10. Freeboard (FB) at the index location was also included in the table and discussed below.
5.3. RISK & UNCERTAINTY SUMMARY
The USACE probability of exceedance and uncertainty analysis procedure used in the HEC-FDA program is used to determine if the levee system has a CNP between 90 and 95%, with a minimum of 3 ft of freeboard added to the computed water surface elevation of the 1 % ACE (Ref. 13). As discussed, the results from the HEC-FDA analysis confirmed that the evaluation reach has a 92% non-exceedance probability for the 1 % ACE with greater than 3 ft of freeboard.
6. INTERIOR FLOOD CONTROL AND SIDE DRAINAGE
6.1. GENERAL CONSIDERATIONS
No interior flood control or side drainage facilities were originally planned for Phase 2.
However, additional inspection of available topographic mapping and site visits were conducted by RCFC&WCD. As a result, additional side drain facilities were designed and constructed to ensure that all local runoff is intercepted and conveyed to facilities that will allow it to enter the channel without significant erosion of the side slopes. Hydraulic and civil design details of the side drainage facilities have been prepared following standards provided by the local sponsor.
6.2. SIDE DRAIN DESIGN HYDROLOGY
The side drain design hydrology for Phase 2 was prepared with the same criteria and procedure used for constructed Phase 1.
6.2.1. Introduction
15 This section of the report presents the results of the hydrology study for the existing and proposed side drain flood control facilities, excluding the major open channels that covey flows to the Murrieta Creek channel (i.e. Warm Springs Creek and Santa Gertrudis Channels), as shown in Figure 8. The hydrology analysis work was provided by the RCFC&WCD which is the lead local sponsor agency providing in -kind services to the USACE.
6.2.2. Purpose
The purpose of this study is to determine the peak flows tributary to the tributaries of Murrieta Creek. The primary objective of the hydrologic analysis was to determine the 100-year discharge at various concentration points along Murrieta Creek utilizing the RCFC&WCD methodology.
These peak flows were used to determine the adequacy of the existing facilities and the need to construct new facilities, which would daylight at the proposed locations to safely convey the tributary flows to Murrieta Creek Channel. Other locations utilized the use of earthen ditches to collect local flows from small tributary areas and direct it longitudinally alongside the access maintenance roads to an adequate inlet then to an underground facility under the access road and into the channel. The hydraulic solutions for each concentration point along the Murrieta Creek project varied depending on the complexity of each situation.
6.2.3. Precipitation
Point precipitation frequency estimates data were researched from the following sources:
• RCFC&WCD maintains records of precipitation data through rain gauge stations within Riverside County. The District analyzes these data based on methods described by the State of California, Department of Water Resources (DWR) in Bulletin Number 195. • RCFC&WCD hydrology manual published maps.
• NOAA ATLAS 14.
After evaluating the precipitation data NOAA ATLAS 14 frequency estimates were used and summarized in Table 11.
6.2.4. Methodology
A Civil Design Computer Software program, HEC-1 Flood Hydrograph Package, was used in performing the hydrology studies in this section of the report. The program utilizes the Rational Table method and the Synthetic Unit hydrograph method described in RCFC&WCD's Hydrology Manual (Ref. 16) depending on the acreage of each tributary area. Three areas in this study ranging from approximately 400 to 700 acres utilized the Synthetic Unit Hydrograph method, all other areas ranging from approximately 0.1 acres to 300 acres utilized the Rational Table method.
6.2.4. Results
16 Results from the Civil Design Software program are summarized in Table 12: Subarea Design Discharge Data.
6.3. SIDE DRAIN FACILITIES
All existing pipes that drain into the channel will be protected in -place or upgraded based on the subarea design discharges provided by the RCFC&WCD. To prevent excessive erosion of the embankment slope, the existing and proposed pipes will include case -in -place concrete headwall and wingwalls. Energy dissipaters were added at the outlet for pipes that were 48" and higher in diameter since the channel is a soft bottom. Hydraulic Design Chart 722-6 Storm Drain Outlets from the Hydraulic Design Criteria Notebook was utilized in the design (Ref. 17). The H&H Policy Memo No. 1 for Side Drain Connections into Flood Control Channels (Ref. 18) was used to supplement criteria found in EM 1110-2-1601 (Ref. 12), which is appropriate for side drain inlets within the los Angeles District. All pipes will be extended to the new channel alignment.
Table 13 is a list of side drains that will directly discharge into the channel.
6.4. DITCHES
Local surface runoff will be intercepted and collected by means of small earthen ditches, lined with a turf reinforcement mat (TRM), which extends along the landside of the maintenance road.
The ditch will convey the flow to an on grade grated drop inlet, into an existing or new pipe and then discharged into the natural channel. The ditch will be V-shaped with typical side slopes of 3H:1 V (unless where noted) and one foot in depth. The short-term maximum velocity for (Lanklok 450) unvegetated channels is 12 ft/s (per Propex Geosynthetics brochure).

Table 6: Local Pier Protection Summary
From FHAW's Hydraulic Engineering Cir. No. 23, 2009 (Determine local pier scour) Vdes = K1K2Vavg; where
K1 = shape factor equal to 1.5 for round -nose piers
K2 = velocity adjustment factor for location in the channel (ranges from 0.9-1.7), use 1.3 ave V,vg = average velocity at bridge (from HEC-RAS)
D50 = 0.692(Vdes)2 /( Sg-1)2g; where
D50 = particle size for which 50% is finer by weight
Vdes = design velocity for local conditions at the pier Sg = specific gravity of riprap (usually taken as 2.65) G = acceleration due to gravity (32.2)
T = thinkness of riprap

MURRIETA CREEK PROJECT PERFORMANCE RELIABILITY
Computation of Uncertainty of Stage -Discharge Relationships - Phase 2, 1 & 1A Prepared by: Mylene Perry 6 February 2014
Refs.
1. HEC-RAS project "Reach2.prj"
2. Engineer Manual EM 1110-2-1619, Risk -Based Analysis for Flood Damage Reduction Studies, 1 August 1996.
Basic uncertainty relationships from Ref. 2:
St = (Snatnret2+ S.0.2)o.5 (Eqn. 5-6, page 5-5)
where S t = standard deviation of total uncertainty
S nat,,,at = standard deviation of uncertainty related to watershed characertistics S model = standard deviation of uncertianty related to computations from hydraulic model Snat-1 = (0.07208 + 0.04936 Iced - 2.262xl0"7 Ab-in + 0.02164 Hn,,y + 1.4194xl0-5 Q 100 )2 (m) (Eqn. 5-5, page 5-4) where 'Bed = stream bed identifier related to bed material A basin = drainage basin area (km2)
HRange = maximum expected or observed range in stage (m) Q 100 = peak discharge from 100-year flood (m3/sec)
Smadat = Ew, l4 (ft) (Eqn. 5-7, page 5-6)
where Egan = mean difference in stage between upper and lower limit water surface profiles (ft) Values for Ibed assigned using Ref. 2, Table 5-1, based on bed material noted in Ref. 5.
For HRanga the minimum water surface elevation is the channel invert, since the channel is essentially ephemeral with no flow for much of the year. The maximum water surface elevation is assumed to be a foot above the lower levee top elevation.

Summary
The Murrieta Creek Sedimentation Model Set -Up Report was prepared for the United States Army Corps of Engineers -Los Angeles District (the Corps) in support of the Murrieta Creek Flood Control and Environmental Restoration Project. The purpose of the report is to summarize the information used and the steps taken in the development of the sediment mode.
With -Project Sediment Transport Analysis
A one dimensional sediment transport analysis was performed using the HEC-6T, Sedimentation in Stream Networks, program. The sediment transport model extends from the Slaughter Canyon to the USGS Gage Station near First Street in the City of Murrieta. The model network consists of the Murrieta Creek (main stem) and the Warm Spring and Santa Gertrudis tributaries (branches), Figure 3.
Secondary flow sources (i.e. Carter Canyon, Long Canyon), project features (detention basin, channelization, new vegetation), and bridges are also accounted for in the model. The hydrologic routing of flows was completed in the feasibility phase using the HEC-1 program.
Previous studies for the without -project condition, WEST Consultants, "Murrieta Creek Flood Control and Environmental Restoration Project -Final Initial Sedimentation Analysis Report", Ref. 11, hydraulic analysis for the with -project condition, completed by the Corps, and hydrologic analysis for the with -project condition, completed by the Corps, "Murrieta Creek Feasibility Study, Appendix C", Ref. 8, contributed in the sediment model development. Information included into the model was sediment source locations, bed and bed material gradations, bed material load rating curves, geometry information for the with -project condition, and hydrographs for the with -project condition.
The objective of the sedimentation analysis was to determine the impact of the project on the hydraulic and sedimentation conditions along Murrieta Creek and the effect hydraulic and sedimentary changes would have on the flood control and environmental features of the project. Special attention was given to modeling the detention basin.
The sediment transport model was verified in a fixed -bed mode to an existing steady state hydraulic model for the with -project condition. A computational instability test was completed for the 100-year with -project hydrologic scenario.
The 100-year event corresponded to the design discharge. 2 Table of Contents

Introduction
1.1. Purpose
The purpose of the Sedimentation Model Setup Report is to document the work completed for the Murrieta Creek Flood Control and Environmental Restoration Project with -project sediment model. The write up focuses on the development of the sediment model, with an emphasis on HEC-6T records and model features unique to modeling the detention basin and accounting for the total load (bed material and wash loads).
1.2. Study Area
Murrieta Creek begins near the City of Wildomar, in the South -East Corner of Riverside County in Southern California. The Creek flows approximately 12 miles south, through the Cities of Murrieta and Temecula eventually joining Temecula Creek to form the Santa Margarita River.
The Murrieta Creek watershed is a valley bounded by the Santa Rosa Mountains and the Santa Rosa Plateau to the west. Rugged, steep hills and canyons make up the southern border. The San Jacinto ranges make up the eastern border, and gently rolling terrain makes up the northern area. The Murrieta Creek watershed study area is 222 square miles at the USGS gage located near the City of Murrieta.
The minimum elevation is approximately 970 feet (NGVD) at the downstream stream gage. The maximum elevation is 4,563 feet (NGVD) near the eastern boundary of the watershed. Most of the watershed consists of valley and mesa lands.
Murrieta Creek is supported by several significant tributaries (Santa Gertrudis Creek and Warm Spring Creek) and by some lesser ones (Empire Creek, Long Canyon, Kalmia Wash, Cole Canyon, and Slaughter Canyon). Two reservoirs are located within the watershed, Diamond Valley Reservoir on Warm Spring and Skinner Reservoir on Santa Gertrudis.
Historically, the Murrieta Valley and the Murrieta Creek floodplain have been used for farms and ranches, with the town sites of Murrieta and Temecula serving as the centers of local commerce and culture. Within the past two decades, the density of residential development and the amount of commercial and industrial development have been steadily increasing. The Murrieta Creek 100-year floodplain impacts 2,504 acres within the Cities of Murrieta and Temecula. Public facilities impacted by flooding include streets, bridges, utilities, and two wastewater treatment plants.
The project area extends from Tenaja Road downstream to the outlet at the gagging station below First Street. 15,000 ft of the Murrieta Creek would be channelized, a detention basin constructed at the confluence with the Warm Spring tributary, and vegetation established along the new river channel. 7 2. Pertinent Information
Setting up the sediment model was simplified by the availability of geometric, sedimentary, and hydrologic information from previous studies.
2.1. Geometry
The geometry information for the with -project features (channel, detention basin) were imported from the with -project hydraulic model'. The without -project sedimentation analysis completed by WEST Consultants, "Murrieta Creek Flood Control and Environmental Restoration Project -Final Initial Sedimentation Analysis Report", Ref. 11, was used to acquire the necessary information for coding the Murrieta Creek tributaries and bridges2.
The detention basin geometry was based on design information developed by the Corps3. Information for the detention basin was extracted from the digital terrain model (dtm) to HEC-6T through geo-RAS and the ras2h6t executable which converts the RAS geometry file to the HEC-6T format. Irregularities in the digital terrain model for the detention basin were initially adjusted in the HEC-RAS with - project hydraulic model prior to exporting into HEC-6T. The dtm file used was preliminary and provided the outer extents and location of the cross section.
Station -elevation points were coded using engineering judgment.
2.2. Hydrologic Data
All hydrographs used in this study were generated by the Corps for the feasibility study, Ref. 8. The hydrologic routing of flows through the detention basin was based on the feasibility study Alternative 6 HEC-1 results4. The fixed bed model ran the assumed 100-year and 10-year detention basin outlet peak discharges.
2.3. Sediment Transport Information
The sediment source locations, transport function, bed material and bed material load gradations, and bed material load rating curves were based on the without - project sediment mode12. Wash load information and computation of the total load was based on a previous Corps study, "Murrieta Creek Sedimentation Model Progress Report, May, 2005", Ref. 7.

3. Existing Without -project Sedimentation Analysis
The work completed for Ref. 11 consisted of a without -project sedimentation analysis5. The model network as proposed in the original sediment model was maintained for the with -project model. Sediment source locations and bed material transport information were all used based on the without -project sediment model.
3.1. Geometric Model
The without -project model for the Murrieta Creek accounted for Murrieta Creek from Slaughter Canyon to USGS Gage Station near First St. Slaughter Canyon is approximately 12,000 feet upstream of the project boundary, Tenaja Road. The two primary tributaries were included in the model network, Warm Spring Creek and Santa Gertrudis Creek. Both tributaries are modeled as branches and are subject to sediment transport and hydraulic computation routines. The branch geometry information was transferred over into the with -project sediment model in its entirety.
The HEC-RAS model had included sediment deposition into the geometry file. For the HEC-6T models all deposition reflected in the HEC-RAS model was removed.
3.2. Sediment Transport Function
Yang's 1973 sediment transport function was used. Yang's 1973 formula was developed for sand transport and accounts for only the bed material load. Yang's formula is suitable for sand and gravel bed streams such as Murrieta Creek.
3.3. Sediment Sources
The without -project sedimentation analysis accounts for the sediment inflow from four local point sources (Long Canyon, Line D, Cole Canyon, Kalmia Wash), two tributaries (Warm Spring Creek and Santa Gertrudis Creek), and the contributing watershed at the upstream boundary. Line D and Kalmia Wash were previously determined to not contribute sediment to the main stem6. The without -project did not account for the wash load contribution.
e WEST Consultants, "Murrieta Creek Flood Control and Environmental Restoration Project -Final Initial Sedimentation Analysis Report", November 2003. HEC-6T file, MCNET.t5 and MCNET1.t5. MCNET.t5 was used for the tributary geometry information, and MCNET1.t5 was used for the inflow/outflow location flow/sediment information. 6 For Line D, e-mail dated 5 November 2003 from WEST Consultants indicated that the sediment load from this tributary was neglected during the preparation of Ref. 11. For Kalmia Wash, Ref. 11 indicates in paragraph 105 on page 40, the sediment inflow, specifically bed material load, from this tributary is relatively insignificant because of a small drainage area and channel dimensions, together with considerable vegetation impeding flow in the channel. E-mail dated 8/11/2005 with WEST Consultants stated that Kalmia Wash had an assumed negligible bed material load but not total load. Wash load has been accounted for.

3.4. Bed Gradations
The bed gradation for Murrieta Creek, Warm Spring Creek and Santa Gertrudis Creek were applied to the with -project sediment model. Refer to HEC-6T model file for gradations used. The bed material inflowing load gradation was also applied to the with -project sediment model, as shown in Tables B-1 to B-5.
3.5. Bed Material Load Rating Curves
The bed material load rating curve for all sediment sources (upstream boundaries and inflow/outflow locations) were applied to the with -project sediment model, Tables B-1 to B-5.
4. With -Project Hydraulic Analysis
The Corps created a one-dimensional steady state hydraulic model for Murrieta Creek using HEC-RAS. The HEC-RAS model7 represented the with -project condition for Murrieta Creek from Tenaja Rd to First St. The discharges run corresponded to peak discharge outflows from the detention basin. In addition, an unsteady hydraulic model for Reach 3 was created to simulate the flow attenuation and determine the maximum water surface elevation during the design flood within the detention basin.
4.1. Geometric Data
The channel geometry information was based on the HEC-RAS with -project geometry file$, project Segments 1 to 4, Segment 1 (River Station 32+00 to 59+00), Segment 2, (River Station 59+00 to 189+00) Segment 3 (River Station 189+00 to 251+00), and Segment 4 (River Station 251+00 to 446+00), Figure A-1.
The geometry information included updated bridge information that was used to code the bridge in the sediment model.
The cross section information accounted for channel modifications, Figure A-8, and a preliminary detention basin design, Figure A-9. The geometry information was converted to the HEC-6T format using the ras2h6t.exe executable file.

Unsteady flow models: project file Reach3.prj, plan file Reach3.p20, geometry file Reach3.gl4, unsteady flow data file Reach3.ul1.
10 4.2. Boundary Conditions
The downstream boundary condition was set to critical depth. Murrieta Creek, at the downstream end, is confined to a steep river reach, with an underlying bed rock outcrop.
4.3. Manning's n Value
Values of Manning's roughness coefficient "n" were incorporated from the with - project HEC-RAS geometry file. Murrieta Creek is predominantly a sand channel with some gravel material. For the with -project condition, the new channel cross section consisted of a low flow channel, vegetated benches and vegetated side slopes. The low flow channel bed material was assumed to be predominantly sandy with no vegetation; the assumed roughness value was 0.027. The bench which will be sparsely vegetated and managed had an assumed roughness value of 0.07. The channel banks with the densest vegetation had the highest associated roughness value of 0.095. The detention basin will be minimally maintained. The main channel roughness was 0.07 and the overbank roughness value was 0.10.
The unchannelized segment of the creek below the downstream end of the project, between Stations 32+00 and 28+75, had an assumed main channel roughness value of 0.053 (cobble and partially obstructed) and an overbank roughness coefficient of 0.06.
4.4. Bridges
There are seven bridges located in the project area: Tenaja Road, centerline Station 444+00; Ivy Street, centerline Station 387+50; Washington Street, centerline Station 333+50; Winchester Road, centerline Station 186+98.5; Rancho - California Road, centerline Station 108+07; Main Street, centerline Station 80+27.5; and First Street, centerline Station 69+39. An allowance for debris loading was set to 2 feet on each side of each bridge pier for the full height of the pier. The width of the piers with the debris loading allowance width ranged from
5.25 to 7 feet, and the height ranged from 6 to 7 feet. The bridge loss calculation method was set to the energy equation for low and high flows.
The detention basin outlet will consist of four ungated 10-ft wide x 11.5-ft high reinforced concrete boxes (RCB's). The approach to the RCB's will be wingwalls flared 30 to 75 degrees. The RCB's will terminate in the existing streambed immediately downstream of the detention basin. The upstream invert elevation of the RCB's will be 1008.63 ft and the downstream invert elevation will be 1008.53 ft.
The length of the RCB's will be 50 ft. A Manning's roughness coefficient of 0.012 was used for the analysis. An entrance loss coefficient of 0.3 and an exit loss coefficient of 1.0 were assumed for the RCB's. The RCB's will be separated by at 11 least 10 ft to allow for compaction of fill between the culverts and to prevent debris from accumulating between the RCB's.
4.5. Peak Flow Values
The steady flow data runs were set to a series of flows corresponding to a range of peak discharges at the detention basin outlet, Table 1. The unsteady flow data was based on the design hydrographs (see the Hydrology Appendix).

5. With -Project Sediment Transport Analysis
The sediment transport analysis was completed using HEC-6T, Sedimentation in Stream Networks, Version 5.13.20. HEC-6T is a quasi unsteady, movable boundary sediment transport program for river networks. The purpose of the sedimentation analysis was to assess the impact of the project on Murrieta Creek sediment and hydraulic conditions and to evaluate the effect the river condition will have on the flood control and the environmental features. The input information was grouped into geometric data, hydrologic data, and sediment data.
The analysis was performed for the with -project condition for Murrieta Creek and its tributaries. The upstream boundary was set at Slaughter Canyon, approximately 2 miles upstream of the project inlet at Tenaja Road. The additional segment of river from Slaughter Canyon to Tenaja Rd. creates a sediment supply reach between the upstream model boundary and the project limit.
The sediment model accounts for major sediment sources, project features, bridges, the flow attenuation due to the detention basin, and the total sediment load flowing into Murrieta Creek. The general Murrieta Creek sediment model network is shown on Figure A-4.
To validate the model a fixed bed simulation for the peak discharges of the10-year and 100-year recurrence interval were run. An initial sediment transport simulation was performed for the 100-year future with -project hydrograph to debug and test the overall stability of the model.
5.1. Geometry Data
As stated earlier the geometry information for the with -project sediment model was based on a previous hydraulic analysis completed by the Corps$. Channel 12 geometry and bridge information were based on this information. Tributary geometry information for Santa Gertrudis Creek and Warm Spring Creek were from the without -project sediment models. For the HEC-6T geometry data, the cross section spacing was increased to roughly 300 to 400 ft, 2 times the channel width. At channel transitions or bridges the cross section spacing was decreased to approximately one half the bottom channel width (-100 ft).
The initial Murrieta Creek network consists of the main stem (Murrieta Creek) and two branches (Warm Spring Creek, and Santa Gertrudis Creek). The branches and main stem are broken up into 8 segments (a segment consists of two endpoints, such as external boundaries or junctions), 9 control points (external boundaries, junctions, and internal operating point), and 10 inflow/outflow locations, Figure A-5. The double ended arrows depicted in the figure indicate inflow/outflow points.
Secondary flow sources (i.e. Cole Canyon, Empire Creek) were modeled as local inflow/outflow points.
Special features of the sediment model are the closed loop used to simulate the hydraulic variability in the detention basin and the internal operating records used to model the outlet structure for the detention basin.
The following discussion will focus on the development of the main stem of the sediment model. For additional information concerning the tributary branches refer to Ref. 11.
5.1.1. Detention Basin Geometry
The detention basin is located in -line with Murrieta Creek, between the confluences of Warm Spring Creek and Santa Gertrudis Creek. Warm Spring Creek flows directly into the upstream end of the detention basin while the Santa Gertrudis confluence is located immediately downstream of the detention basin outlet. In the HEC-6T model the detention basin extends from Station 260+00 to Station 193+00.
The detention basin serves flood control, environmental, and recreation purposes.
The environmental component consisted of new vegetation. The recreation features consisted of submergible athletic fields. Local sponsors required a controlled management plan for sediment removal. It had been assumed that certain areas within the detention basin would be set aside for sediment removal activities. Initial design plans, Figure A-2, identify a main channel, an environmental area separated by an earthen berm, and a recreational area. The outlet structure was based on the feasibility study Alternative 6, "Murrieta Creek Flood Control, Environmental Restoration and Recreation, Feasibility Report", Ref.
6. 13
The detention basin geometry was based on the unsteady flow model(s). Three different basin geometries were simulated in the HEC-RAS models. Three alternatives for ecosystem restoration were analyzed to decrease the embankment height. Alternative 1 consists of full ecosystem restoration, i.e. constructing islands within the basin and a fully vegetated bottom. This alternative is based on a conceptual ecosystem restoration plan prepared by Aspen Environmental.
Alternative 2 consists of no islands within the basin but with a fully vegetated bottom. Alternative 3 consists of lowering the entire bottom of the basin, no islands, and a fully vegetated bottom.
The complexity of the detention basin required a prioritization of functions that need to be simulated in the sediment model. Not all of the physical processes can be simulated in the model, but as long as the most critical are present the model should adequately represent the physical processes that are critical in simulating the detention basin. The detention basin model functions, in order of importance, that need to be simulated are as follows:
1) Simulating attenuation of flows.
2) Simulating deposition/erosion trends in the basin.
3) Accounting for the cohesive sediment transport.
Keeping these three points in mind, the geometric model was developed for the Murrieta Creek detention basin as discussed in the following paragraphs.
5.1.1.1 Simulating Attenuation of Flows
Simulating the attenuation of flows through the detention basin was the most critical task. HEC-6T is a quasi -unsteady model, that is, the hydraulic computation scheme treats the input hydrographs as a series of steady state discharges of specified durations for which the program performs a backwater calculation.
Channel storage is not accounted for, so that flow attenuation is not addressed.
The hydrologic routing of the flows must be accomplished externally and then imported into the model.
To simulate the flow attenuation, several discrete inflow/outflow locations that convey water but not sediment were added to the model. The HEC-6T program allows the user to assign discrete points which can contribute or divert flows completely out of the model network. These points are referred to local inflow/outflow points and are represented by the QT record.
To realistically simulate the attenuation of flows, the detention basin was broken up into six physically different areas: Area 1, dominated by the Murrieta Creek inflow; Area 2, dominated by the Warm Springs Creek inflow; Area 3, the Murrieta Creek — Warm Springs mixing area; Area 4, the main channel conveyance area; Area 5, the overflow area provided by the main part of the basin; and Area 6, the outlet area.
14 The discharge attenuation and the water surface elevations within the basin were determined from a HEC-RAS RAS unsteady flow hydraulic model, which has the capability of accounting for outlet control and a variable tailwater elevation that affects the outflow from the basin. The HEC-1 hydrographs were used for the remainder of Murrieta Creek. These hydrographs were imported into an Excel spreadsheet$ to get them into the proper HEC-6T format.
The local inflow/outflow points (QT records) requires a discharge -sediment rating table with the corresponding gradations,

HEC-6T Example 1. Local Inflowing sediment load rating curve.
The HEC-6T program requires a sediment discharge rating table prescribed by grain size fractions at each of the local inflow/outflow points designated on the QT records. Since the purpose of the artificial diversions is only to simulate the flow attenuation in the basin, and also since no sediment is physically transported into or out of the basin boundaries except at the upstream and downstream ends (Control Points 2, 3, 6, and 7), the values for the sediment discharge rating table must be set to zero. In addition, the required grain size fraction data for the rating table is irrelevant and is not used in the calculations.
5.1.1.2 Simulating Deposition/Erosion Trends in the Basin.
The basin was modeled one -dimensionally. The previous design plan separating the environmental feature from the main channel, Figure A-7, to reduce the deposition which would occur in the environmental area, was modified. The berm, which separated the main channel from the environmental area, was removed from the model. Instead, wide cross -sections that span the entire basin were utilized.
Ineffective flow limits were used to limit the conveyance area. In cases where there are islands in the basin, vertical and horizontal ineffective flow limits were placed downstream of the islands to simulate the ineffective area caused by the islands. Deposition and erosion will be allowed throughout the entire cross- section.
a Detention Basin inflow/outflow hydrograph calculations and an in depth discussion can be found in the "DSStoHEC6tConv0 .xls" excel worksheet series. Each event requires a separate determination of the inflow/outflow hydrographs. 15 A sediment trap was added at the mouth of the Warm Springs tributary. The sediment trap was accounted for on two cross sections, Station 0.50 and 0.51, in the Warm Springs Creek branch, Segment 7. An artificial pilot channel was added to the sedimentation model to improve the program stability. The pilot channel is located at the center of the overflow spillway from the sediment trap to the environmental area on Segment 5. The channel is .4 ft wide and 1.4 ft deep, and the invert elevation is at the main channel elevation. The pilot channel is only located at the sections that represent the overflow spillway. The pilot channel improves the performance because at low flows, some small flow would flow into Segment 5, thus ensuring the cross sections are always wet.
The sediment material flowing into Segment 5 was eventually adjusted to allow clay, silt, and a limited amount of sand to pass. Refer to Section 5.2.2 for a more detailed discussion on this matter.
5.1.1.3 Accounting for the Cohesive Sediment Transport
At the time of this study, the only information dealing with the cohesive sediment available was sediment yield estimates for the Murrieta Creek watershed. The gradation for the material associated with sediment yield was determined using USDA soil survey data, Soil Survey, Western Riverside Area, California, Ref. 9.
Utilizing this info and the hydrologic data from the with HEC-1 results, a wash load rating curve and gradation were developed. For the full explanation of this procedure refer to USACE-SPL document "Murrieta Creek Sedimentation Model Progress Report, May, 2005", Ref. 7.
5.1.2. Inflow/Outflow Locations
Flow and sediment sources not modeled as tributaries were represented as inflow/outflow locations (QT records). The sediment model accounts for 4 sources modeled as local inflow/outflow locations, Table A-2. Locations QT EC, QT KW and QT CC contributed sediment laden flow. Location QT LID only contributed water.
5.1.3. Bridges
To code the bridges, three cross sections were used to represent an upstream, bridge and downstream section. Bridges which have decks that can be overtopped by flows less than the peak discharge for the 100-year event were coded with the deck and roadway using an S-type method specific to HEC-6T program, Sedimentation in Stream Networks (HEC-6T), Users Manual, Ref 2. 16 XL 10700 8-119.98 216.24 400 400 400

HEC-6T Example 2. HEC-6T Bridge Code.
The debris loading allowance included in the HEC-RAS with -project geometric data was incorporated without modification.
5.1.4. Manning's n value
In the HEC-6T program, cross sections are typically subdivided into three subsections: the left overbank, the main channel, and the right overbank.
However, the with -project HEC-RAS model disregarded flow in the overbanks because it is not necessary for the project design flood that is conveyed entirely within the channel. For that reason, the bank stations in the HEC-RAS model were set at the top of the channel side slopes and corresponded to the first and last coordinate points, respectively. For consistency, the HEC-6T cross sections were coded in the same manner. However, it is necessary to specify separate roughness coefficients for the channel and both overbanks, even if the overbanks are not included in the cross section geometry. This programming constraint was solved by using a single composite value of Manning's roughness coefficient n for the channel and both overbanks. The composite value of n was set at the value of the conveyance -weighted n computed by the HEC-RAS program, which has the capability to account for a variation in hydraulic roughness within the channel limits to properly reflect differences in flow characteristics across the channel boundary.
In addition, the variation in n value with flow depth was accounted for by using the NV record in the HEC-6T program. Again, the single composite n values were taken from the HEC-RAS output for a range of discharges.
Data prescribing the hydraulic roughness for the HEC-6T program is entered on the NC and NV record for each cross section. To simplify the data entry, the hydraulic model was broken up into several reaches of relatively uniform hydraulic roughness, as shown on Figure A-12. The initial values of hydraulic roughness 17 were then specified only at the downstream end of each reach, since the HEC-6T program will retain the NC and NV data for all upstream sections until new data is encountered at the next reach. It should be noted that these initial values of roughness were adjusted later during the model validation process.
The weighted Manning's n values in the channel ranged from 0.025 to 0.07. Since there will be minimal maintenance to the vegetation in the basin, a Manning's roughness coefficient of 0.10 was used for the area within the basin and 0.070 for the low flow channel.
Several locations do have overbank roughness values in excess of 0.1. These areas correspond to ineffective or low flow areas due to obstructions.
5.1.5. Ineffective flow limits
The configuration of the basin will limit conveyance to the main channel and portions of the environmental area. The recreational area will provide no conveyance. To account for these ineffective flow regions, conveyance limit records (XL) were used. The XL records were also used for the overlapping portion of cross sections representing Segments 4 and 5. Later variations of the model removed the overlapping portion of the cross sections limiting the need for the ineffective flow limits to the recreational area.
5.1.6. Movable bed deposition and erosion limits
A typical cross section of the channel is displayed in Figure A-8. The entire channel bottom, including the vegetation terraces, was assumed subject to deposition and scour. However, the top of the banks were assumed fixed and not movable. Therefore, following the data coding requirements of the HEC-6T program, the movable bed limits were set at a point immediately outside of the toe of the outer bank, as shown in the figure.
5.1.7. Bed Sediment Reservoir
The bed material depth was set to the default value 10 ft for all cross sections except for Station 28+75, the furthest downstream cross section. Station 28+75 had an assumed depth of 1 ft because of the bed rock outcrop located at the section. The bed sediment depth was set with the HD records only9.
5.2. Control Points
Control points refer to junctions, external boundary conditions, and internal operating rule records. The with -project Murrieta Creek HEC-6T model has 10 9 Note that the bed sediment depth for Warm Spring and Santa Gertrudis tributary segments were set to 20 ft. Refer to the without -project HEC-6T file, MCNETLO for more details.
IN
control points, 4 external boundary conditions, 4 junctions and 1 internal operating rule record, as indicated in Table A-1 and Figures A-3, A-4 and A-5.
5.2.1. External Boundaries
Each branch of the sediment network has an upstream boundary condition (CP 3, CP 7, CP 8) which requires a hydrograph; all hydrographs must have the same time step (Section 5.3.1).
At the network outlet (CP 1), the boundary condition was specified as a rating table ($Rating) based on the water surface elevation - discharge relationship from the HEC-RAS model. The table information was taken directly from the HEC-RAS with -project hydraulic model results for Station 28+75 for the range of discharges shown on Table B-13.
5.2.2. Junctions
Junctions are located at the intersection of two or more segments. The HEC-6T program inherently conserves energy and mass at all junctions. However, the program also allows the user the flexibility of prescribing a regulation of the sediment load by size class at the junction of a tributary or flow diversion.
5.2.3. Internal Operating Rule Record
The effect of the detention basin outlet structure on the detention basin water surface elevation was accounted for by an internal operating rule which sets the water surface elevation at the outlet structure, this then causes a backwater affect throughout the detention basin. An internal operating rule record (X5) allows the user to assign the water surface elevation at a location for each time step in the R record. The X5 record breaks the backwater calculation at the point of occurrence and routes the flow from the most immediate upstream to the next downstream.
The X5 sequence consisted of two cross sections an arbitrarily small distance apart.

HEC-6T Example 4. internal Operating Rule Record (X5).
19 Since the detention basin outflow is also a function of the tailwater elevation below the detention basin outlet structure, an unsteady flow hydraulic model using the HEC-RAS program was used to refine the calculation of the water surface elevation in the basin for the R records, as well as the reduction in discharge that is discussed in Section 5.3.1 below.
5.3. Hydrologic Data
The hydrographs used in HEC-6T were imported from the HEC-1 hydrologic routing program output file. Hydrographs for the 3 upstream boundary points and 5 inflow/outflow locations were generated from the future with -project 100-year HEC-1 file 14. This was the assumed design event. The hydrographs within the basin were from the unsteady HEC-RAS model.
To convert the format of the HEC-1 and HEC-RAS hydrograph output data to the input format required by the HEC-6T program, the hydrographs were exported from HEC-1 to DSSVue. From DSSVue the hydrographs were transferred to an Excel spreadsheet10 to write the hydrograph records (*,Q,R,T,W records).
All hydrologic information had a 10 minute duration time step.
5.3.1. Hydrographs
The 100-year with -project event hydrograph was used to test the overall stability of the sediment model. The HEC-6T program does not perform any kind of flood routing computations to calculate the attenuation in flow through a reservoir; rather, at each time step only a steady flow backwater calculation is completed. Flows are combined at junctions and local inflow/outflow locations but the flows are not routed. To maintain the timing of flows as they enter the detention basin, artificial flow diversions were set up with the QT record at the locations labeled D134 and DB5. The resulting adjusted hydrograph are very nearly the same as the original HEC-1 computed hydrographs, Figures A-10 and A-11. The HEC-1 network model is shown in Figure A-6.
An antecedent flow hydrograph was also generated for the 100-year hydrograph.
The antecedent condition was assumed to correspond to an event that is 30% of the 100-year event in terms of the peak discharge. The approach of arbitrarily reducing the inflowing and outflow hydrographs by 70% to represent the antecedent flow conditions was considered but not taken because it would not properly or accurately reflect the flow attenuation and hydrograph lagging caused by the detention basin. Instead, the antecedent flow hydrographs were generated by re -running the HEC-1 with -project model for rainfall depths 30% of the 100-year rainfall event. The computed hydrographs were roughly 70% less than the 100- 10 Excel based hydrologic computing and exporting tool, DSStoHEC6tconv.xls. 20 year hydrographs, as desired, and the resulting hydrograph data was added before the design flood hydrograph data, as illustrated on Figure B-8.
The peak discharge of the design event was 20,000 c.f.s. at HEC-1 CP 8, 15,300 c.f.s. at HEC-1 F5-A6, detention basin outlet, and 23,200 c.f.s. at HEC-1 CP 1, USGS gage station location.
5.3.2. Detention Basin Routing
The inflow/outflow hydrograph records were based on hydrographs from unsteady flow computations with the HEC-RAS program.
The outlet structure was represented by the X5 record (Section 5.2.3).
5.3.3. Downstream Boundary Condition
The downstream boundary condition at Station 28+75 of Segment 1 was specified by using the rating curve record, Table B-1311, refer to Section 5.2.1.
5.3.4. Computational Options
The computation time step was equal to the hydrograph time step, 0.0069 days, or 10 minutes.
HEC-6T allows the user two ways to modify the cross section shape, 1) adjusting the elevation of each point below the water surface elevation equally or 2) by varying the change in elevation of each point in proportion to the depth of flow at each point. By assigning the $GR record the program gives the user the option between the two methods, otherwise option 1 is default method. The initial runs used the default method.
To allow the user more flexibility in writing cross section coordinate records, the cross section coordinate editor record was activated (GE). This was found useful in organizing complicated cross section coordinates for the bridge and detention basin cross sections.
Rating curve only applicable for msr_4 HEC-6T series. All remaining file use R records. There is no computational difference between the two.
21 5.4. Sediment Data
For the Murrieta Creek model both bed material load and wash load were accounted for. The detention basin would affect both coarse and fine material.
The coarse material is normally accounted for in the bed material load, but the fine material (fine sands, silts, and clays) is associated with the wash load. By entering the total load, the full sediment load passing into the detention basin will be accounted for. This was essential in simulating the sedimentary processes occurring in the detention basin.
Sediment gradations and bed material and wash load rating curves were taken directly from previous studies12.
Modeling both bed material load and wash load requires specifying the non - cohesive and cohesive sediment transport equation or methods.
5.4.1. Non -Cohesive Transport Equation
The traditional approach for selecting a transport function involves collecting field data, including both suspended sediment measurements and bed material gradations; processing and testing that data with a number of sediment transport functions; and then selecting the function that best matches the field measurements. Since sediment measurements of Murrieta Creek were not available, the transport functions used in the sediment budget analysis were selected using SAM.aid, which is a module of the SAM package that provides guidance in the selection of the most applicable sediment transport functions to use with a given river or stream. The transport functions selected by SAM.aid are summarized in Table A-9.
As shown in the table, the transport function that is recommended for Murrieta Creek is Yang (D50), which is Yang's original Unit Stream Power equation. This equation has been successfully used in sediment studies on sand bed rivers in the Western United States in general and in the Los Angeles District in particular.
Further basis for selecting Yang's equation is presented in a USDA report, Selecting a Formula to Estimate Sediment Transport Capacity in Non -vegetated Channels (Ref. 12). This report documents an investigation that was made into the sediment transport formula that best estimates the sediment transport capacity of non -vegetated channels. Of the many transport equations available, eight suitable sediment transport function theories were examined and tested against a range of available field and flume data. The notable conclusion of that study is reproduced as follows: "Of all the tested formulas, therefore, only the Yang formula can be used with confidence to predict sand -transport capacities over the range of flow conditions usually encountered in non -vegetated channels". Although Murrieta 12 The bed material information was determined in the without -project sedimentation analysis (Ref 11). The wash load information and the total load information were completed by the Corps (Ref. 7). 22 Creek has vegetation within the channel during the periods of low flow, it is very likely the vegetation will wash out during the larger floods when the majority of the sediment is being transported.
The second best transport function recommended for Murrieta Creek is Yang's equation. As explained in the SAM User's Manual, this equation is a version of Yang (D50), which has been modified to calculate sediment transport capacity by grain size classes.
5.4.2. Cohesive Transport Equation
Silts and clays were accounted for in the initial Murrieta Creek sedimentation model. Two cohesive transport equations are available; one accounts only for the deposition of cohesive sediment based on settling velocities. The other computes deposition and erosion of cohesive sediments based on Krones equation and the Ariathurai method respectively, HEC-6 Scour and Deposition in Rivers and Reservoirs, Ref. 4. For the Murrieta Creek sediment model, only deposition of silts and clay was accounted for, since significant scour or re -entrainment of these fine particles from the detention basin bottom is not expected. However, during the sensitivity testing of the model, the re -entrainment of the fines from the bottom of the basin should be evaluated by comparing the calculated bottom shear stress at selected locations throughout the hydrograph against the default and example values provided in the HEC-6 user's manual. This topic may be important if re - entrainment is likely to reduce the net deposition of sediment within the detention basin.
The cohesive sediment transport equation is defined on 12 and 13 records. Particle size, settling, and erosion variables are assigned here. The default values for the required deposition parameters were used due to a lack of field information.
5.4.3. Sediment Gradation
The sediment load gradation at each of the boundaries and inflow/outflow locations account for both the wash load and the bed material load, or the total load. For an in-depth discussion of each of the contributing sediment loads refer to the previous studies.
The sediment gradation ranges from fine clay to very coarse gravel, but is predominately sand. The gradations for each upstream boundary and inflow/outflow location which contribute sediment varied with discharge, Table A-3 to A-8. The gradation and rating curves for the wash load and bed material load are found in Appendix B. In addition, an example for total load calculation is provided in Appendix B.
23 5.4.4. Sediment Load
The sediment load at each of the boundaries and inflow/outflow locations account for the total load. Not all inflow/outflow locations transport sediment. The inflow/outflow locations assigned to the detention basin (DB series) have no assumed sediment transport capacity. Line D was assumed not to transport sediment and Kalmia Wash only wash load.
The largest contribution of sediment is attributed to upstream boundary followed by Santa Gertrudis Creek, Table A-3 to A-8.
5.5. Fixed Bed Model
To verify the hydraulic component of the sedimentation model, the model was run for fixed bed conditions for 23,200 cfs. and 6,000 cfs. Results were compared to the hydraulic analysis results for the future with -project condition to verify hydraulically the setup of the sedimentation model.
The fixed bed model is initiated by commenting out all the sediment data records and inflow/outflow locations 13. The inflow/outflow locations are commented out because the with -project hydraulic model did not account for local inflow/outflow locations. The peak discharges used were based on the peak discharge at the gage station near First St. These discharges were applied for the entire stretch of Murrieta Creek. To leave the branch geometry data in the model, arbitrarily small flow values were used for Warm Spring Creek and Santa Gertrudis Creek upstream boundaries.
The internal operating rule record was also commented out to disable the detention basin.
The fixed bed model was used to verify the hydraulic component of the sediment transport model.
5.5.1. Steady Flow Data
Two discharges, 23,200 c.f.s. and 6,000 c.f.s., were run at all the cross section locations.
5.5.2. Water Surface Profiles
The water surface profile comparison showed a good comparison between the HEC-6T and HEC-RAS results for flows tested, Figures B-1 and B-2. The median difference between HEC-6T and HEC-1 water surface elevations was 0.08 and -
0.07 respectively. Differences at the detention basin are attributed to the 13 Fixed bed model files MurfbJ5
24 difference in the cross section geometry information used between the HEC-6T file and the HEC-RAS file.
Based on the water surface profile comparison it was assumed that the hydraulic component of the sedimentation model was acceptable.
5.6. Movable Bed Analysis
The sedimentation analysis was completed for the future with -project condition for the Murrieta Creek Flood Control and Environmental Restoration Project. The model has been tested for the future with -project 100-Year event. The simulated detention basin attenuation is based on the results from the HEC-1 file, fwp6_100.dat.
The initial model for this study was subsequently modified to develop the most appropriate model for the with -project condition. Five movable bed models were developed in all:
Model 1 — This model is the initial movable bed model as described in Section 5.
The model accounts for a split flow condition in the detention basin which was modeled with two segments and five inflow/outflow points to adjust the flow. The detention basin sediment trap was placed on Segment 7, between Stations 0.5 and 0.51. A schematic diagram is provided in Figure A-13. The HEC-6T input file name MSR 1 a.dat.
Model 2 — The initial results from Model 1 indicated depths of deposition along Segments 3, 4 and 5 that may be unrealistically high. To reduce the deposition, the inflow/outflow points in the detention basin were repositioned such that two points were located on Segment 5, one point on Segment 4, the points on Segment 3 were removed, and one point was added to Segments 7 and each. In addition, the amount of water diverted from inflow/outflow points on Segments 7 and 8 was increased.
All other features remained the same. The HEC-6T input file name is MSR-2a.dat.
Model 3 — The large depths of deposition along Segment 4 still remained in the Model 2 results. The deposition at the upstream portion of Segment 4 forced the main channel over to Segment 5.
In an attempt to reduce the amount of deposition occurring in Segment 4, the inflow/outflow sediment rating table for the Segment 4 diversion point was modified to transport sediment from Segment 4 to Segment 5 when the detention basin water level exceeded the top of the berm, 1021 ft. This modification was made to simulate the overflow which would occur physically between Segment 4 to 5. To account for the diverted sediment, a third inflow/outflow point was assigned to Segment 5. The 25 sediment rating table for the new point was based on sediment outflow data from the Segment 4 diversion point. The HEC-6T input file name is MSR-3a.dat.
Model 4 — A review of the results from Model 3 revealed that the attenuation in the detention basin was also accounting for the attenuation occurring upstream of the detention basin along Segment 8. The amount of attenuation turned out to be a significant reason for the large deposition amounts occurring in the detention basin.
To correct this inaccuracy, multiple inflow/outflow points were placed along Segment 8. The flow attenuation along Segment 1 was also corrected by the addition of multiple inflow/outflow points. In particular, one inflow/outflow point was placed on Segment 3, two points were placed on Segment 5, and one point was added to Segments 4 and 7. A schematic diagram is provided in Figure A-14. The HEC-6T input file name is MSR-4a.dat. Model 4 was selected as the preferred model.
Numerous variations of the preferred alternative model were made for the sensitivity tests (roughness, inflowing sediment load, and computational time interval), to perform model runs with antecedent flow conditions, and to account for sediment load modifications. These additional models are listed in Table B-14.
Model 5 — Models 1 through 4 all modeled the detention basin with a split flow condition. This model simulates the detention basin in a considerably simplified manner as a single segment with three inflow/outflow points along Segment 3, formerly Segments 3, 4 and 6. The HEC-6T input file name is MSR 5a.dat.
Model 6 — This is a copy of Model 4 except that the detention basin is modeled as a single segment. This more closely simulates the current configuration of the detention basin. This model simulates Alternative 1 and contains the environmental features. The HEC-6T input file name is MSR_4C14.T5.
Model 7 — This is a copy of Model 6 except that the detention basin is modeled without the environmental features. This model simulates Alternative 2.
The HEC-6T input file name is MSR-4C16.T5.
Model 8 — This is a copy of Model 6 except that the detention basin and Reach 2 was lowered. This model simulates Alternative 3. The HEC-6T input file name is MSR 4C17.T5. Not yet complete — waiting for channel and detention basin geometry.
26 The evaluation to determine the most effective approach consisted of reviewing scour/deposition amounts along Murrieta Creek and within the detention basin.
The model that adequately represented the general deposition trends that would be expected in the basin, act computationally stable, and provide reasonable scour/deposition estimates, was deemed the most effective. A list of all model runs is found on Table B-14.
5.6.1. Results
Overall, the models were stable, and the results were generally as expected. The detention basin traps almost all the sand, some silt, and very little clay. Segment 1 and 8 showed signs of degradation. Most of the degradation on Segment 8 occurs in the sediment supply reach upstream of the project inlet. The degradation may be an indicator that the inflowing sediment load should be increased to achieve the assumed condition of sediment transport equilibrium at the upstream end of the project.
The longitudinal bed change profile for each model, Figure A-15 and A-16, show similar bed change patterns. The channel reach from Station 540+00, the upstream boundary, to Station 300+00, upstream of the detention basin, appears to be degrading. As expected, aggradation occurs in the detention basin.
Immediately downstream of the detention basin is some minor scouring, followed with substantial scouring in the downstream most sections, from Station 28+75 to 34+50. This apparently excessive scour could possibly be caused by an inaccurate downstream boundary condition in terms of the tailwater rating curve or the need to shift the curve periodically throughout the flood to reflect the effect of computed deposition. The trap efficiency results shown in Table B-15 indicate that Segment 5 has the highest overall value, followed by Segment 4 and Segment 7.
Although the different models indicate the same general trends of aggradation and degradation, the computed changes in bed elevations varied considerably. For example, Figure A-15 shows a relatively large difference in the maximum computed positive and negative bed elevation changes for both Models 1 and 2; Model 2 resulted in as much as 8.6 ft of deposition and 5.9 ft of scour, and Model 2 resulted in values 6.3 and 7.7 ft, respectively. Therefore, the results from Models 1 and 2 were judged not as plausible or as sensible as the results from Models 3, 4, and 5, especially in terms of the spatial distribution of the changes in bed elevation.
In particular, Models 1 and 2 indicated relatively large and localized changes that would not be expected in the detention basin.
The detention basin for Model 5 was set up as a single segment. The major benefit of this model is that the simulation and therefore the HEC-6T program data coding for the detention basin is greatly simplified and thus much easier to apply to design refinements. However, the major disadvantage is that the simulation of the basin with only a single segment may unduly oversimplify the flow attenuation and sediment transport processes, and therefore could seriously underestimate the 27 deposition of sediment within the basin. In particular, the conveyance is defined by one continuous strip extending across the main channel and the environmental area. As a result, the sediment transport capacity is based on average hydraulic variables for the entire width of the active area of conveyance. The computed sediment depth change is averaged over the whole width, resulting in higher rates of deposition within the environmental area and lower rates in the main channel area.
Models 3 and 4 showed similar trends but Model 4 had more deposition in Segment 5 and less in Segment 4, and Model 4 was more stable to run. Model 4 was the preferred model because it satisfied the three major requirements; adequate representation of scour/deposition trends, stability, and plausibility of results. The results for Model 4 are discussed below. However, due to the changes in the detention basin configuration and environmental features, Model 4 is no longer the preferred model. The results will still be discussed below since only the geometry within the basin was changed; the rest of the model is the same.
The bed change profiles for Segment 5, Figure A-16, shows aggradation, predominately fine and medium sand with some silt and clay. The limited amount of fine deposits along Segment 5 can be attributed to the short detention time.
Even though the flow peaks and channel velocities were reduced, the lessened velocities coupled with the relatively short detention time are still not sufficient to cause more fine material to deposit.
Certain locations within the detention basin were deemed critical for ensuring a stable model: Station 248+00 in Segment 4; Station 197+00 in Segment 3; and all of Segment 5. Station 248+00 was located immediately downstream from a flow split and served as the primary segment for conveyance. The model computationally would deposit extreme amounts of sediment to compensate for the reduction in flow. In some cases this would prevent water from flowing into Segment 4. The user should consider this model tendency when evaluating the model results.
The hydrologic input data also caused problems when an inflow/outflow point diverts more or equal to the computed segment discharge such that the resulting flow is negative or zero. The HEC-6T program documentation refers to this condition as reverse flow. This problem occurred more frequently during low flows and on Segment 5 or Segment 4. The erroneous computed flow reversals are caused by a limitation in the input format for the HEC-6T program, which requires values of inflow or outflow discharge, rather than a fixed percentage or fraction of the hydrograph being modified. To correct this problem, the diverted flows need to be adjusted by the user to eliminate the flow reversals. The reverse flows do not reflect an intrinsic instability in the model, but rather an external variable that requires an iterative approach to prevent too much flow from being diverted at a single point. The following is an example of a typical HEC-6T warning message regarding flow reversals:
WARNING.. A CLOSED LOOP WITH A LOCAL INFLOW HAS A FLOW REVERSAL. THATS NOT PERMITTED.
SEGMENT #, LOCAL INFLOW POINT #: 1 4
QMAIN1, QMAIN2, QLOCALO= 11.70 0.00 -11.70
SUBROUTINE BWMOD4
HEC6T PROGRAM: WARNING MESSAGE 24001
HEC-6T Example 6. Output Warning Message for a Reverse Loop.
The flow reversal errors were eliminated in Models 6, 7 and 8 since the detention basin was not modeled as a closed loop in these models.
During the sedimentation model development, a computational error was discovered in the wash load inflow spreadsheet, and the wash load inflow and total sediment inflow rating curves had to be recomputed. However, the revised inflowing load data was applied only to the recommended model, which is Model 4.
The updated HEC-6T file is msr_4c.dat. The files created for the sensitivity tests and the expanded hydrograph for antecedent flow were all based on the revised Model 4 file.
As expected, Models 6 and 7 showed similar trends to Model 4. Only the results within the detention basin will be discussed in the following paragraphs since the channel geometries of Models 6 and 7 are copies of Model 4.
The detention basin traps almost all the sand, some silt, and very little clay. The sediment analysis results show aggradation, predominately fine and medium sand with some silt and clay. The limited amount of fine deposits along the basin can be attributed to the short detention time. Even though the flow peaks and channel velocities were reduced, the lessened velocities coupled with the relatively short detention time are still not sufficient to cause more fine material to deposit.
For Model 6, the sediment analysis results are as follows. During the peak of the design hydrograph, the upstream half of the detention basin would experience an average bed scour of 1.2 ft. The low flow channel would undergo scour while the overbanks would undergo deposition. The downstream half of the detention basin would experience an average bed deposition of 2.2 ft. Sediment would deposit in both the low flow channel and the overbanks.
At the end of the design hydrograph, the upstream half of the detention basin would experience an average bed scour of 0.7 ft. The low flow channel would undergo scour while the overbanks would undergo deposition, except at the Warm Springs confluence with Murrieta Creek where up to 4.4 ft of deposition would occur. The downstream half of the detention basin would experience an average bed deposition of 1.7 ft. Sediment would deposit in both the low flow channel and the overbanks.
29 Similarly, for Model 7, the sediment analysis results are as follows. During the peak of the design hydrograph, the upstream half of the detention basin would experience an average bed scour of 1.0 ft. The low flow channel would undergo scour while the overbanks would undergo deposition. The downstream half of the detention basin would experience an average bed deposition of 2.2 ft. Sediment would deposit in both the low flow channel and the overbanks.
At the end of the design hydrograph, the upstream half of the detention basin would experience an average bed scour of 0.4 ft. The low flow channel would undergo scour while the overbanks would undergo deposition, except at the Warm Springs confluence with Murrieta Creek where up to 3.5 ft of deposition would occur. The downstream half of the detention basin would experience an average bed deposition of 2.1 ft. Sediment would deposit in both the low flow channel and the overbanks.
Model 8 not yet complete -- waiting for channel and detention basin geometry.
The following sensitivity analysis was performed using Model 4 as the basis14
5.6.2. Sensitivity Analysis — Sediment Load
The sediment inflow load rate at the upstream boundary of the model as well as for the tributary locations was increased and decreased by 30% to test the sensitivity of sediment load on the computed change in channel bed elevations. The input gradation information was not changed.
Based on the longitudinal bed profile, Figure A-17, the model did not appear to be sensitive to the changes in sediment load. There were some locations within the detention basin, Segment 4 Station 248+00, that responded to the change. Overall the influence of sediment load appeared minimally
As stated in Section 5.6.1, the degradation on Segment 8 may be an indicator that the inflowing sediment load should be increased to achieve the assumed condition of sediment transport equilibrium at the upstream end of the project. The inflowing sediment load was increased by 50% to determine if the equilibrium assumption could be achieved. This was not the case, however, in that degradation still occurred in Segment 8. Nevertheless, since the upstream end of the model is located a long distance upstream of the project reach, any adjustments required for the sediment load should not significantly affect the results within the project reach. 14 At the time of the determination of the preferred model the sediment load information was revised to account for changes in the sediment load information. The new file was msr 4c.dat, all remaining models reflect the new information. Applicable to HEC-6T input files msr_4c.dat to msr 4j.dat.
is The tabular information for the HEC-6T bed results are found in the excel file "HEC 6T Results.xls". 30 5.6.3. Sensitivity Analysis — Manning's n Value
The Manning's n values for all cross sections were increased and decreased by 30% to test the sensitivity of the roughness on the computed change in channel bed elevations.
Based on the longitudinal bed profile, Figure A-18, the model appeared to be sensitive to roughness changes. The decrease in roughness caused scouring from Station 560+00 to 510+00, and to a lesser degree throughout the remainder of Segment 8. The material transported downstream from the scouring caused increased deposition in the detention basin, which in turn resulted in further erosion immediately downstream of the detention basin. The increase in roughness had less of an effect on the computed change in bed elevation.
5.6.4. Sensitivity Analysis — Computation Time Interval The computational time interval is equal to the hydrograph time step, 10 minutes or
0.0061 days. To test the computational time interval the duration was increased to 1 hour, 0.042 days.
The results showed that the model remained stable and the results were similar to the results of the 10 minute computation time interval, Figure A-17. These results lead to the conclusion that the HEC-6T model can be run at a longer computational time interval than originally performed. As long as the volume, duration and peak are preserved, the hydrologic simulation of the event would be compromised.
Comparison of the two hydrographs is shown in Figure B-4. Only a slight reduction in runoff volume is observed for the 1 hour duration hydrograph.
5.6.5. Antecedent Hydrograph
To test the HEC-6T model response to a longer, more typical event, an antecedent hydrograph was attached to the design discharge hydrograph. The antecedent condition was assumed to be equivalent to 30% of the design event. Two cases were run, one case with the antecedent hydrograph preceding the design hydrograph, Figure B-8, msr_4d1.dat and a second case with antecedent hydrograph before and after the design hydrograph, msr-4d2.dat.
The duration of the design hydrograph is 1.48 days, the design and preceding antecedent hydrograph is 2.78 days, and the antecedent hydrographs before and after the design hydrograph is 4.2 days. Results show that the additional flow, albeit lower than the design event, increases deposition within the detention basin, decreases the scouring along Segment 1, and increase scouring along the supply reach, Figure B-9. The supply reach had scour depths up to 10 feet, which leads to the conclusion that the sediment loading entering through the upstream boundary is less than what is necessary to satisfy the assumption of sediment transport equilibrium and a stable reach.
31 6. Summary
The preferred HEC-6T models, Models 6, 7 and 8, appeared to adequately represent the deposition variation that would occur in the basin, act computationally stable under various conditions (i.e. change in sediment load, roughness and computation time interval), and provide reasonable scour/deposition estimates (deposition/scouring no greater than 6 feet16) The results from the models are best evaluated in a comparative analysis for which the results are averaged over a reach of cross sections with similar hydraulic and sedimentary characteristics. By evaluating reaches rather than cross sections, the results are more meaningful, because uncertainties in the input information and irregularities in the results are dampened over a larger area. The model should be grouped into reaches that are roughly two to three thousand feet in length.
Application of one-dimensional model such as HEC-6T to the hydraulic and sedimentation characteristics of the detention basin that are at least somewhat two-dimensional is questionable. However, most of the two-dimensional nature of the basin is relatively limited to localized areas at the inlet and outlet. In addition, the HEC-6T sedimentation model has been set up to provide essentially a quasi - two dimensional simulation of sedimentation trends by separating the channel and environmental restoration / flood control storage area with two different model segments. For those reasons, a one-dimensional model is considered adequate for the objective of estimating the general trends of aggradation expected within the basin, and assessing the impact of the resulting loss of flood control storage on the flow attenuation performance of the basin.
6.1. General Comments and Recommendations for Further Work The various sediment inflow tables for high flows are exceeded; however, the tables were not extended for the initial model setup, because the model extrapolates up or down if the value is not within the limits of the table.
Nevertheless, it would be prudent to externally extend the tables to ensure a reasonable inflowing sediment load relationship over the full range of flows being simulated.
It is recommended that a mass balance analysis be performed to ensure that all sediment material has been accounted for.
For the low flow conditions the model warns of movable bed limits above the water surface elevation. This condition does not appear to have any impact on the model performance, although it would be prudent to verify this presumption with a careful review of the detail hydraulic and sedimentation output, at least at selected locations for selected points throughout the hydrograph. 16 Scour depths in excess of 5 feet were observed from Stations 28+00 to 33+00 assumedly caused by the downstream boundary condition.
32 The bed shear stress analysis for fine particle entrainment was not performed.
However, as indicated previously, significant re -entrainment of silts from the bottom of the detention basin is not expected, except possibly near the entrance to the outlet structure where the local flow velocities are expected to increase.
To run longer events the computation time interval may be increased. However the attenuation flow distribution variables may need to be adjusted to ensure that reverse or negative flows do not occur along Segments 4 or 5. This requirement also holds true for any changes to the current Model 4 version.
To confirm deposition trends along Segment 5, the fine material settling velocity should be specified in the program output and utilized to prepare a separate manual assessment of the required settling time and distance. A good example to follow is the settling analysis of the detention basins prepared for the sedimentation analysis of the Arizona Canal Diversion Channel (ACDC) project in Phoenix.
There appeared to be a pair of unstable time steps in the antecedent hydrograph.
They were commented out at the time of the study. It is uncertain why the time steps created instability.
Additional insight into the sedimentation model performance and the plausibility of the results can be gained by comparison to the without -project sedimentation model prepared by WEST Consultants. In addition, the comparison will also reveal a qualitative estimate of the impacts of the project on the sedimentation characteristics of the stream.
