Viewing GeoSWMM 2D Outputs

There are two ways to visualize the 2D flood map:

1)     Automatic Generation: After the 2D model simulation is complete, save the GeoSWMM project. The maximum flood water depth map will be generated immediately.

2)     ArcGIS layer properties: You can view and customize the 2D flood result from the 2D cell layer properties in ArcMap.
