Once the HEC-RAS (or HEC-2) analysis has been performed, RiverCAD will generate a detailed floodplain map of the computational results?showing the extent of the flooding on the AutoCAD drawing. Very precise edge of water mapping is created?greatly speeding up the process of creating final map submittals for agency review. Automatically generates approximate (FEMA Zone A) and detailed (FEMA Zone AE, AH) flood maps. Water surface elevation contours, commonly called BFE¡¯s (base flood elevation) contours, are automatically constructed and labeled. Flood depth contours can be generated in order to create flood hazard mapping. The user has total control over line style, line color, line weight, hatching, and other drawing configuration parameters in order to meet any specific corporate CAD drafting standards.
