2 . Water Surface Profile Model. The computer program HEC-RAS will be <br /> used to develop water surface profiles and flood boundary and floodway <br /> delineations . Valley cross section information will be developed utilizing <br /> digitized topographic data and field surveyed stream sections and bridge <br /> data. Water Surface profiles will be developed for the 10-, 25-, 50-, <br /> 100- and 500-year flood events . Flood boundaries will be developed for the <br /> 100- and 500-year events, and floodways will be developed for the 100-year <br /> event. Water surface profiles will be developed for both present and <br /> future conditions . <br /> 3. Flood Reduction Alternatives. Develop conceptual flood reduction <br /> alternatives which can be used to make decisions concerning management of <br /> stormwater runoff. <br /> 4 . Report preparation and training. A technical report will be provided <br /> at the end of the study explaining the methodology used to develop the <br /> models. Corps of Engineers personnel will assist the local sponsors in the <br /> use of any models developed during the study. <br /> FUTURE WORK ITEMS: Depending on future funding abilities of both the Corps <br /> of Engineers and the local sponsors, the study effort may be expanded to <br /> include planning for more comprehensive watershed management. Future work <br /> items may include: <br /> 1 . Alternatives for flood damage reduction planning <br /> a. Flood warning systems <br /> b. Comprehensive watershed planning database <br /> C. Digitized Flood Plain mapping <br /> d. FIS digitized mapping <br /> e. GIS mapping for State water plan <br /> 2 . Economic Analysis studies <br /> Flood hazard evaluation studies <br /> 3. Environmental planning <br /> Wetland delineation and assessment <br /> 4 . Hydrologic/Hydraulic studies <br /> a. Hydrologic Modeling for non-point source pollution <br /> b. Future retention basin studies <br /> 5 <br />
