I am currently trying to delineate an urban watershed using Arc Hydro tools. I have successfully completed all the Terrain Processing steps up to Catchment Grid Delineation. When I try to run Catchment Polygon Processing I keep getting this error message:
Error HRESULT E_FAIL has been returned from a call to a COM component
I'm not sure what this means. I tried clearing the Temp Folder, Resetting Target Location, and defining the Processing Extent but I still keep receiving this message. Does anyone know how to resolve this??
