FEMA approved models are used to compute water surface elevations for required flood events. Computed water surface elevations and topographic data are used to delineate flood hazard boundaries. Roughness coefficients are carefully selected to represent the conditions along the stream beds and banks. Base Flood Elevations (BFEs) on the FIRMs and in floodway data tables agree with the flood profiles in the FIS.\r\n Hydraulic analysis provides water surface elevations at different locations along the stream and for different flooding events. Hydraulic submittal includes key physical data used in the process, model parameters and model output. Data developed in surveying and hydrologic analysis are incorporated in hydraulic analysis. Results of hydraulic analysis are used to map Special Flood Hazard Area (SFHA) boundaries. Selection of model parameters (e.g. roughness coefficients, expansion and contraction coefficients, etc) is supported by additional information (e.g. landuse, aerial photo, etc). Model boundary conditions are carefully selected and justified.
