Hi all, Long-time GIS user, but first-time water resources/H&H workflow question. I’m working on a project where consultants are developing separate HEC-RAS models for different drainage basins in our city, each producing flood surface results for various design storm events. Once all the modeling is completed, there’s a…
I am working through the Wetland Identification toolset in ArcHydro and am getting this error on a few tools (screenshot below). I am using .tif's only and have tried a few different versions of the input. My project area is pretty small. I would appreciate any insight into how to resolve this. Thanks!
