I have installed ArcHydro for ArcGIS 10.8. The "Flood from Cross-Section" tool is trying to call the script "...floodfromcs.py," but the py file that exists in the install directory is actually named "floodfromcsh.py," so it will not run. Does anyone know why the filename ends with an "h" in my particular install? I'm scratching my head here. Thanks!
