EXECUTIVE SUMMARY The Capitol Complex of Jefferson City, Missouri has experienced flood hazards and flood-related damages as a result of high water levels along the Missouri River and Wears Creek. This Phase II study presents the results of alternatives evaluation for providing flood protection to key infrastructure within the Capitol Complex area. Hydrologic and hydraulic evaluations were performed to define risk of flooding from the Missouri River, from Wears Creek, and from coincidental flooding from both sources. Stage trends along the Missouri River have been incorporated into the hydrologic and hydraulic evaluations. Alternatives evaluation and the development of conceptual designs have been based on providing one foot of freeboard above the 500-year flood event for selected structures within the study area. Pumping facilities have been sized to provide 1 00-year flood protection for such structures in the interior areas of levees or floodwalls. Conceptual design has been completed for the following two alternatives: Alternative No.1: Levee, Flood Gates, and Pumping Facilities at the Mouth of Wears Creek This alternative would provide Missouri River flood protection to certain buildings located within the study area. The levee and flood gates would control Missouri River backwater from extending upstream into the Wears Creek basin. Pumping facilities would be capable of limiting the flood levels upstream of the levee and flood gates by pumping Wears Creek flood water across the levee. Although this alternative would reduce the frequency of flooding due to the Missouri River, this alternative does not improve flooding conditions due to Wears Creek. Buildings that are currently subject to flooding from Wears Creek would con tinue to be at risk. The opinion of probable construction cost is approximately $76 million. Wears Creek Flood Mitigation Study, Phase II State ofMissouri D ivision of Desi gn and Construction 1 Draft Report 5/28/2 003 Alternative No.2: System ofFloodwalls, Gates, and Pumping Facilities This alternative would provide site-specific flood protection to the Truman Building, State Health Laboratory, and Capitol Plaza Hotel from both Missouri River and Wears Creek flood events. Reinforced concrete floodwalls would be constructed around these buildings, with removable gates at vehicular and pedestrian entrances. Pumping facilities would be provided to discharge flood water from the protected area. This alternative also provides an ancillary security benefit of controlling vehicular access to key governmental buildings and infrastructure within the Capitol Complex area. The opinion of probable construction cost is approximately $5 million. Wears Creek Flood Mitigation Study, Phase II State of Missouri Division of Design and Construction 2 Draft Report 5/28/2 003 _I 2. INTRODUCTION Over the last century, the Capitol Complex of Jefferson City, Missouri has experienced flood hazards and extensive damages due to flooding. The flooding has been a result of high water levels along the Missouri River and Wears Creek. In January 2001, the Wears Creek Flood Mitigation Study was prepared for the purposes of evaluating the feasibility ofvarious flood control measures capable of minimizing flood damage in the Capitol Complex area. This Phase II of the Wears Creek Flood Mitigation Study was initiated to further refine the conceptual design of selected flood mitigation alternatives. A general project location map is shown in Figure 1. Figure 1: Project Location Map Wears Creek Flood Mitigation Study, Phase II State ofMissouri Division of Design and Construction 3 Draft Report 5/28/2003 2.1 Study Area The study area includes the right bank of the Missouri River floodplain near the mouth of Wears Creek and the floodplain of Wears Creek in the Capitol Complex of Jefferson City, Missouri. Wears Creek enters the Missouri River at approximately River Mile 143.3. The study area is generally bounded on the upstream side of Wears Creek by U.S. Highway 50. The study area is shown in Figure 2. 2.2 Purpose The overall purpose ofthis project was to evaluate the feasibility of various flood control measures to mitigate flood damage in the Capitol Complex area. The January 2001 Wears Creek Flood Mitigation Study identified several alternatives for flood mitigation based on preliminary hydrologic and hydraulic analysis. Alternatives analysis demonstrated that flood hazards and damages in the Capitol Complex area could be mitigated by a system of levees, floodgates, and pumping facilities. The purpose of the Phase II Wears Creek Flood Mitigation Study was to further define the flood risks, to identify acceptable risk levels and target areas for flood mitigation, to further evaluate selected alternatives, and to develop conceptual level design and costs for such alternatives. 2.3 Methodology Flooding within the Capitol Complex area of Jefferson City can occur from prolonged flood stages along the Missouri River, from flash flooding within the Wears Creek basin, or from a combination of these factors. The rather complex nature of flooding in the study area has been analyzed using various methods as appropriate for each flooding source. Coincidental analysis methods were applied to determine stage-frequency relationships on Wears Creek with respect to Missouri River stages. Wears Creek Flood Mitigation Study, Phase II State ofMissouri Division of Design and Construction 4 Draft Report 5/28 /2003 \ I ) ~) -~-·· .. Figure 2: Study Area Flooding conditions along Wears Creek were analyzed using a Hydrologic Engineering Center River Analysis System (HEC-RAS) hydraulic model as originally developed by the U.S. Army Corps of Engineers. Flood frequency stages along the Missouri River were also provided by the U.S. Army Corps of Engineers. Coincident flood frequency analysis was performed to evaluate the return period of flood stages in the Capitol Complex area based on the dual probability of flood flows on Wears Wears Creek Flood Mitigation Study, Phase li State of Missouri Division of Design and Construction 5 Draft Report 5/28/2003 Creek and independent flood stages on the Missouri River. The coincidental analysis has been based on the assumption that the Missouri River stages and the Wears Creek flows are independent, and therefore the probability of Missouri River tail water and Wears Creek flood flows occurring simultaneously can be computed using the total probability theorem. Though some dependency exists between the two flooding sources, the relatively large size difference between the Missouri River and Wears Creek basins supports this assumption. Analysis was then performed using Hydrologic Engineering Center Interior Flood Hydrology (HEC-IFH) analysis was then performed to evaluate interior flooding conditions, storage volumes, and pumping facilities. The resulting stage frequencies were then compared to determine the flood mitigation affects and levels of protection provided by the various alternatives. 3. EXISTING CONDITIONS 3.1 Available Information Aerial topographic mapping was provided by the Jefferson City Public Works Department and is dated 03/09/1996. The mapping included contours plotted at a two- foot interval. Stage-frequency data on the Missouri River was obtained as available from the U.S. Army Corps of Engineers and included updated stage trend data which is considered preliminary and subject to further Corps review. Hydrologic and hydraulic models from the January 2001 Flood Mitigation Study were utilized during the Phase II evaluations. 3.2 Field Survey Data Field survey data was obtained specifically for the Phase 2 Flood Mitigation Study for the purposes of identifying flood risks relative to key infrastructure within the study area. Such data consisted of first floor and low entry elevations for several key buildings Wears Creek Flood Mitigation Study, Phase II State of Missouri Division of Design and Construction 6 Draft Report 5/28/2003 • within the study area. A summary of the surveyed elevations is presented in Table 1. Photos of selected survey locations are provided in Appendix A.

This curve also included future stage trend data available from the Corps at the time of the study. The future stage trend data available in 2001 suggested a Missouri River stage increase of2.33 feet for all flood frequencies by the year 2031. Since the 2001 study, the Corps has conducted a restudy of these stage trends and has developed updated future stage trends on the Missouri River near the mouth of Wears Creek. These new stage trends are subject to further Corps review, however, such trends are believed to represent the best available data at this time. These updated stage trends indicate projected increases in Missouri River stages ranging from 2.59 feet for the 0.5% exceedance probability to 1.01 feet for the 0.002% exceedance probability by the year Wears Creek Flood Mitigation Study, Phase II State ofMissouri Division of Design and Construction 7 Draft Report 5/28/2003 2031. This updated stage trend data has been applied during the coincident frequency analysis ofthis study. 565.0 560.0 :r ~ 555.0 ~ Q) ~ 550.0 u; 545.0 540.0 Figure 3 Stage vs. Exceedance Probability for Missouri River J. < I , •• / ..• v # ;, . ., v -·· .. v # ~ / .. .

The analysis was conducted using an HEC-RAS model ofWears Creek as provided by the U.S. Army Corps of Engineers. The HEC-RAS model was reviewed and found to be generally representative of the Wears Creek channel and existing hydraulic structures, with two primary exceptions. First, the existing railroad bridge at the mouth ofWears Creek was represented as a twin box culvert structure in the Corps' HEC-RAS model. Based on visual identification and railroad documentation, the existing structure has been identified as a stone arch bridge. Second, the geometry of the existing Wears Creek channel between the railroad bridge and the Main Street bridge did not appear to Wears Creek Flood Mitigation Study, Phase II State of Missouri Division of Design and Construction 8 Draft Report 5/2 8/2003 consistently represent actual conditions. Revisions have been made to the HEC-RAS model to reflect the stone arch bridge dimensions (22ft. x 43 ft.) available from railroad documentation, and channel geometries between the railroad bridge and Main Street were modified based on available contour data. The hydraulic analysis along Wears Creek indicates that the main channel is generally capable conveying somewhere between a 2-year and 5-year flood event. Larger flood events will flood the overbanks areas, and can cause flooding oflow-lying infrastructure and buildings. Table 2 presents a summary of the overtopping frequency of the various bridges and roadways within the Capitol Complex area. Table 2 Summary of Roadway or Railroad Overtopping Frequencies State of Missouri, Capitol Complex Area Approximate Roadway/Railroad Overtopping Frequency* Union Pacific Railroad 500 Year ' Main Street 25 Year i Walnut Street (Missouri Blvd.) 10 Year ' High Street > 500 Year r McCarty Street 15 Year ' US Highway 50 25 Year ' *Overtopping frequency based on Wears Creek flooding only. The hydraulic analysis indicates that neither the existing railroad bridge nor the Main Street bridge directly result in significant backwater flooding upstream . In fact, removal ofboth of these bridges has been found to reduce flood elevations upstream by less than one foot. Flooding upstream of both of these bridges appears to be more directly related to the U-shaped concrete-lined channel in the vicinity of the Main Street bridge. This portion of channel causes significant backwater conditions upstream of Main Street. A plot of the water surface profiles along Wears Creek from the HEC-RAS analysis is presented in Figure 4 .

The results of the coincident flood-frequency analysis are presented in Figure 5, which displays inundation areas for various coincidental flood frequencies. Figure 6 shows coincident hydraulic profiles. Figures 7 through 12 display the stage-frequency relationships for Wears Creek, the Missouri River, and coincident flooding at several locations within the study area. Table 3 presents a list of several key buildings in the study area that are subject to flooding. The first floor elevations have been identified from previous studies and available data provided by the State. The approximate flood frequency of each particular building is noted in the table. This flood frequency is based on the coincident flood analysis and thus considers the total probability of flooding from both Wears Creek and future Missouri River stages.

Interior Drainage Modeling The evaluation of pumping facilities for areas to be protected by levees or floodwalls has been conducted by using the US Army Corps of Engineers interior flood hydrology model, HEC-IFH. This model was used to generate the interior runoff volumes from Wears Creek and to evaluate the interior ponding in response to closed gates and different pumping scenarios. 3.6.1 Basin Average Precipitation The HEC-IFH model was used to calculate basinwide peak runoff for the different hypothetical storm events. This model uses basin average precipitation for the different hypothetical storm events. The precipitation data for the Wears Creek watershed was from TP-40 database. The 500-year event was extrapolated from the TP-40 data. TP-40 precipitation for the Jefferson City area is tabulated in Table 4.

The required parameters for the SCS curve number method are the basin area, weighted curve number for the watershed based on land use and soil type, percent impervious, type of unit Wears Creek Flood Mitigation Study, Phase II State ofMissouri Division of Design and Construction 17 Draft Report 5/28/2003 hydrograph and lag time. The basin area was calculated using GIS as 14.27 square miles. The percent impervious was calculated using available aerial photographic mapping. The weighted average percent impervious was estimated as 65%. The Wears Creek watershed is comprised of 5% industrial, 31% residential and 64% commercial land uses. The curve number calculation requires hydrologic soil type and land use data. The Wears Creek watershed is characterized by 35% ofthe total watershed as hydrologic soil group Band 65% as hydrologic soil group C. the SCS lag time was calculated to be 2.1 hours. The unit hydrograph used in the HEC-IFH model was the SCS dimensionless. 3.6.3 Interior Storage Volume The stage-storage data was calculated using the GIS based on 2-foot contour mapping. The stage-storage data was used in HEC-IFH to analyze the interior water surface and ponding scenarios due to gate closure and pumping. Table 5. shows the interior stage- storage relationship at the mouth ofWears Creek.

For the purpose of this study, seepage was assumed to be negligible. The updated Corps stage trend data on the Missouri River was used in this study to optimize the pumping capacity. 3.6.5 Gravity Outlet The revised HEC-RAS model, representing the existing railroad bridge at the mouth of Wears Creek as a stone arch bridge, was used in conducting the HEC-IFH analysis. The invert elevation at the upstream face of the existing railroad bridge was determined to be 528 feet. 4. ANALYSIS OF ALTERNATIVES 4.1 Alternatives and Assumptions The consequences of flooding in the study area can include property damage to both structures and contents, interruption ofbusiness and emergency operations, road closures and delays, clean-up and maintenance efforts, public safety hazards, and adverse affects on the local and regional economic viability of the Capitol Complex area. The identification and development of flood mitigation alternatives for the Capitol Complex area are based on consideration of acceptable levels of flood risk, hazards and damages. The primary objective of this flood mitigation study has been directed towards reducing the frequency of flooding and flood-related damages for key infrastructUre. Table 6 lists the field surveyed elevations of several key buildings and infrastructure that are subject to flood damages during significant flood events. The alternatives developed and evaluated as part of this study focus on reducing the flood frequency of these key buildings from Wears Creek Flood Mitigation Study, Phase II State of Missouri Division of Design and Construction 19 Draft Report 5/28/2003 both Wears Creek and Missouri River sources. The alternatives evaluation has been based on providing flood protection to the elevations shown in Table 6. Table 6 Target Flood Protection Locations and Elevations Building Elevation Description Truman Building 564.0 feet First floor, McCarty St. entrance -.. State Health Laboratory 560.6 feet First floor 563.5 feet First floor Environmental Control Center 561.7 feet Electrical transformer pad Capitol Plaza Hotel 560.9 feet West entrance fmished floor Jefferson City Distributors 565.1 feet First floor entrance along McCarty St.. The target level of protection to be provided by the structural components of each alternative is the 500-year flood recurrence interval with one foot of freeboard. Pumping facilities required to convey stormwater from interior drainage areas have been sized to provide flood protection from the 1 00-year flood recurrence interval. 4.2 Alternative No. 1: Levee, Flood Gate, and Pumping Facilities at the mouth of Wears Creek The improvements proposed for this alternative include raising the existing railroad embankment by approximately 6 feet to an elevation of 562.1 near the confluence of Wears Creek and the Missouri River, removing and replacing the existing railroad bridge with a triple box culvert and outlet structure, with each culvert bay having a span and rise of 18'x14', and incorporating a 6,300 cfs pump station with 12 propeller style vertical turbine pumps into the box culvert (see Figure 17). Near the outflow end ofthe box culvert, large roller gates would be installed to control Missouri River backwater affects when the river is at flood stage. From an operational standpoint, reconstructing the railroad embankment at a higher elevation and to levee requirements would prevent floodwaters of the Missouri River from reaching the City during river flood stage. The roller gates on the downstream side of the box culvert would be closed to prevent Wears Creek Flood Mitigation Study, Phase IT State ofMissouri Division of Design and Construction 20 Draft Report 5/28/2003 floodwaters of the Missouri River from backing up into Wears Creek and flooding the City. When the gates are closed, water from Wears Creek would be pumped through large pipes in the levee and into the Missouri River. The level of flood protection from the Missouri River provided by this alternative would be the 500-year. The pumping capacity of the pump station would be the 100-year return period for the Wears Creek watershed. The proposed modifications to the levee do not require the alignment to be changed from the existing. The limits of the levee improvements would be from U.S. Highway 54 to the northwest, to Adams Street to the southeast, which is a total linear distance of approximately one mile. The top of the new levee would be constructed to an elevation of 562.1 feet, which provides a minimum freeboard of one foot from the floodwaters of the Missouri River during the 500-year flood stage (561.1 ft MSL). Currently, the top of the levee has an average width of about 80 feet and the proposed levee cross section is also 80 feet. The embankment material used to construct the levee improvements would be a combination of random fill and impervious soils. For cost estimating purposes it was assumed that rock lining would be placed on the river-side bank of the levee from a location just below where the earthen fill starts to the top of the levee. The volume of random fill and impervious materials has been estimated to be about 48,788 cubic yards and 20,909 cubic yards respectively. The required amount ofrock lining was assumed to be 18,320 cubic yards. Figure 13 illustrates how the levee may be reconstructed and provides the basis for the assumptions used in determining the levee quantities to prepare the opinion of probable cost. The fmallevee design may be significantly different from figure 13 and is dependent upon an in-depth analysis of the existing embankment conditions. Prior to preparing the final levee design, an in-situ soil analysis and an investigation of subsurface soil conditions, using closely spaced borings, and exploratory drilling, must be performed to determine the appropriate levee design. Wears Creek Flood Mitigation Study, Phase II State ofMissouri Division of Design and C onstruction 21 Draft Report 5/28/2003 IMPE OUS FILL 500-YR WSE S7 RIP RAP NORMAL WSE y Figure 13: Levee Construction \ \ EXISTING RAILROAD \ EMBANKMENT Levee Cross Secti.on ROCK The top of the levee contains a substantial amount of railroad track infrastructure which increases the cost and complexity of this alternative. On the south end of the proposed work there are eight parallel railroad tracks. Towards the north end of the levee the number of tracks is reduced to three . It is assumed that the railroad tracks along the levee are main lines, meaning that they are the railroad's primary track that extends great distances and carries both freight and passenger trains. It is also assumed that the property rights for the levee area belong to one or more of the major railroads; therefore, railroad project approval and coordination with the railroad(s) will be key to making this alternative feasible. Reconstruction of the levee could be done in phases to keep the railroad lines open. Temporary shoe-flys and bridges could be built to allow the trains to travel around the Wears Creek Flood Mitigation Study, Phase IT State of Missouri Division of Design and Construction 22 Draft Report 5/28/2003 construction work. Construction easements would likely have to be obtained from the railroad(s) and from adjacent property owners to perform the work. When preparing the assumed vertical profile of the levee for this alternative, railroad track approach and departure slopes of0.3% were used to minimize the grade change of the tracks. The approximate total length of track to be removed and replaced is 31,000 feet. Construction of the proposed triple box culvert, and raising the track elevation, will require the existing railroad bridge to be replaced with a new structure. While the new bridge is being built, a temporary bridge would allow railroad traffic to pass over Wears Creek. Retaining walls would likely be necessary in some locations along the west side of the railroad's right of way so that the levee elevation can be raised without adversely affecting site grading for adjacent property owners. Where practical, embankment would be placed on adjacent properties to raise them up with respect to the new levee. The type of gates that will be used at the outlet structure of the triple box culvert to control Missouri River backwater during a flood stage event is a breastwall roller gate. Roller gates move up and down vertically, and are available in sizes to fit this application, which is an 18' span by 14' rise. The number of roller gates required for this triple box culvert is three, one for each bay. The breastwall type of roller gate is designed to operate where the water is considerably deeper than the height of the gate and where complete closure is required. Typically, roller gates are designed for face pressure only. Since the operation of this pump station will require the roller gates to be closed before the Missouri River reaches floodstage, the roller gates must be specially designed to account for back pressure from Wears Creek. Double rails must be installed and the sealing system must be augmented to minimize leakage from the backpressure. Operation of the roller gate is accomplished using a gear lift. Due to the size of the gate and the fact that it must be designed to operate under backpressure, the gate would be too heavy to operate manually, therefore, it must be electrically actuated. There will be four lift stems for each of the three gates, and a minimum of two electric actuators will be required for each gate. The installation location of the gates will be on the river side of the levee (See Figure 14). Wears Creek Flood Mitigation Study, Phase II State ofMissouri Division of Design and Construction 23 Draft Report 5/28/2003 Figure 14: Breastwall Roller Gate --e> ~LOW Because of the limited site area available for the pump station, the design must be compact, and the construction logistics will be challenging. Since there is not sufficient space to create a storage pond to pump from when the roller gates are closed, flows from Wears Creek must be pumped immediately to the Missouri River. The proposed pump station facility has 12 vertical-turbine-propeller pumps; 4 pumps will be placed in series in each culvert bay. The proposed pumps have an inlet diameter of 84 inches and a flow capacity of approximately 525 cfs each for a total pump station flow rate of approximately 6,300 cfs, which will provide the 1 00-year design storm protection for the targeted buildings. This design concept based on driving the pumps with diesel motors rather than electric. The use of diesel motors to drive the pumps will greatly reduce the electrical power requirements of the station and are more reliable during flood events when electrical power may not be available. A site concept plan showing the location of the pump station and the levee improvements is shown in Figure 15 . A sketch of the Wears Creek Flood Mitigation Study, Phase II State of Missouri Division of Design and Construction 24 Draft Report 5/28/2003 pump performance curve follows in Figure 16. A schematic diagram of the proposed pump station is shown in Figure 17.

Buildings that are currently subject to flooding from Wears Creek will still be at risk when Wears Creek reaches flood stage. In order to reduce future flooding from Wears Creek, other improvements along the creek, such as improving the hydraulics of the bridges at Main Street, and Walnut Street, and enlarging the channel downstream of the Main Street bridge would have to be made. There are ancillary/incidental flood control benefits provided from this alternative. Flood relief from the Missouri River provided by the raised levee and pump station would be extended to many more properties than the three structures protected by the floodwalls proposed in Alternative No.2. Under Alternative No. 1, most of the buildings, infrastructure, and personal property in the downtown portion of the Wears Creek watershed could be protected from Missouri River flooding. Clearly, the economic benefit from this alternative includes much more than flood protection for the buildings noted in this report. The opinion of probable cost for this alternative is $76 million. The basis of the costs is information obtained from suppliers of pumps, gates and other components ofthe proposed work. Additional sources for the estimated cost includes RS Means and project bid tabulations from recently completed projects. The components that make up the opinion of probable cost are concrete and earthwork, pumps and controls, gates and appurtenances, site restoration, engineering and incidentals necessary for construction of this design alternative.

This alternative has been developed based on providing flood protection at these buildings to the elevations shown in Table 6. Three building-specific floodwalls would be constructed and remain in place at all times. During flood events, the entrance gates would be put in place by emergency crews to seal off the driveway and pedestrian entrances. Submersible sewage pumps, installed in below-ground wet wells, would be located inside of the flood wall barriers to pump storm water outside of the protected area. This alternative does not include floodwalls at the Envirorunental Control Center or Jefferson City Distributors since the elevations listed in Table 6 for each of these structures are above the 500-year flood levels. Reinforced concrete floodwalls would be constructed around the Truman Building, Capitol Plaza Hotel, and the State Health Laboratory (see Figure 18: Floodwall Site Drawing). The height of the floodwalls varies from approximately 2 feet up to 12 feet. The length of each of the flood walls is shown in Table 7. The two typical flood wall types proposed for use in this alternative are shown in Figure 19. Type L walls are suitable for heights of 60 inches; greater wall heights require type T construction.

In addition to flood control, this alternative provides the ancillary security benefit of controlling vehicular access to key governmental buildings in the Capitol Complex area of Jefferson City.

The components which make up the work for this alternative include concrete floodwalls, earthwork, pump stations and appurtenances, gates to provide access through the floodwalls to the protected buildings, site restoration, engineering and other miscellaneous items required for the construction of the design alternative. A detailed Opinion of Probable Cost is provided in Appendix D. 5. CONCLUSIONS This Phase II study has further defined the risks to various buildings and infrastructure due to flooding from Wears Creek and the Missouri River. Acceptable levels of risk and specific target areas for flood mitigation have been identified through field survey data collection, hydraulic analysis, and coincident flood analysis. Two alternatives have been developed with the purpose of providing flood protection to the buildings and infrastructure at the elevations presented earlier in Table 6. A side-by- side comparison of the two alternatives is presented in Table 8.

KCD in 1984. The pedestrian bridge between Main St and Missouri Blvd was not included because it. had no hydraulic impact . It totally spans the creek and there are no piers. Note: The Southwest Blvd Bridge and Ford a>arking lot were modeled as the geometry of the location dictated. Howe v er, graphically it appears that water re-enters the channel between the roadway and the parking lot, which is not physically possible . Therefore , on the plot of the water surface elevation, the water surface from the downstream face of the parking lot was connected with the water surface at the upstream face of the SW Blvd Bridge . The Frog Hollow portion of this model {from cross sectioon 13050 to 26020) is based on existing data developed by Black and Veatch for the Cole County Flood Insurance Study . The basin was examined to ensure that the stream geometry had not been greatly modified. Roughness coefficents and ineffective flow areas were adjusted to reflect current conditions. There are two bridges upstream of West Stadium Drive, one under west Edgewood Drive and one under Frog Hollow Road. Both were field verified to ensure that current geomet.ry was included i n t.he model. A flood.way run was attempted but results made little engineering sence:. There was very little consistency in topwidths and encroached velocities. >85\ of the cross sections were encroached to the channel stations therefore it was assumed that the floodway would be aet at the channel stations with no change in the water surface elevation between the f load way and natural condi tiona.
