Map Exporting

To export the 2D flood results:

1. Use Generate Flood Raster tool in GeoSWMM 2D  

Export map using “Generate Flood Raster” tool

The Generate Flood Raster tool can be used to create and visualize higher resolution raster file of 2D flood model results. This tool will activate after the simulation of 2D model. With the aid of this tool, the research area's maximum water depth and water surface elevation (wse) can be visualized for the duration of the simulation.  The output of the 2D findings requires the management of a separate geodatabase. The user has the option to simultaneously select any or both of the depth and WSE rasters.

The interface of this tool looks like the following:

Steps:

• Set the default geodatabase or browse a predefined geodatabase file.  

• DEM layer is directly assigned from GeoSWMM project 

• Assign the output raster cell size or import the raster of required cell size, otherwise keep it as defaults 

• Check the required output raster 

• Update the raster name or keep it as defaults 

• Click “Generate”.
