Map Exporting
To export the 2D flood results, follow these steps:
Using “Generate Flood Raster” tool in GeoSWMM 2D
The Generate Flood Raster tool can be used to create and visualize higher resolution raster files of 2D flood model results. This tool activates after the simulation of the 2D model. With the aid of this tool, the maximum water depth and water surface elevation (WSE) of the study area can be visualized for the duration of the simulation. The output of the 2D findings requires the management of a separate geodatabase. You have the option to simultaneously select either or both of the flood depth and WSE rasters.

The interface of this tool looks like the following:

Set the default geodatabase or browse a predefined geodatabase file.
The DEM layer is directly assigned from the GeoSWMM project
Assign the output raster cell size or import a raster of the required cell size. Otherwise, keep the default cell size.
Check the required output raster (e.g., Max Flood Depth Layer)
Update the raster name or keep it as default.
Click “Generate” to create the raster files.
