![]() The Flood Map dialog box will be displayed.From the Results ribbon menu, select the Flood Map command.If not, first perform a HEC-RAS flow analysis for the defined model.įollow the steps below to create the water surface elevation raster grid: Take note that this same process can be used to generate raster grids for other flood results, such as maximum velocity flood maps.įor the flood map and corresponding water surface elevation raster grid to be generated, the HEC-RAS model analysis results must be available. ![]() This section describes the process used to generate a water surface elevation raster while generating the flood map. Creating a Water Surface Elevation Raster Grid The following section details how this is done. It is a simple process to direct the software to generate a corresponding raster grid file while generating a flood map.
