I have ArcGIS Desktop 10.5, ArcHydroTools_x64 and HEC-GeoHMS 10.2 installed. I am able to run Preprocessing, Project Setup, and Basin Processing on the GeoHMS toolbar. When I run Characteristics or Parameters on GeoHMS, I get errors saying: "Tool not found. Please add GeoHMS Tools on the toolbox and try again!". For example when I run River Length on Characteristics, I get the following error: "RiverLenght tool not found. Please add GeoHMS Tools on the toolbox and try again!" I was able to load Arc Hydro tools into ArcToolbox, however I don't know how I can load GeoHMS tools into ArcToolbox. Please assist me. Thanks
I would first start by installing the HEC-GeoHMS 10.5 version. The U.S. Army Corps of Engineers is no longer upgrading the software, but ESRI is currently doing updates and placing them on an ESRI web site: http://downloads.esri.com/archydro/HECGeoHMS/Setup10_5/
This site contains many applications that support/work with the ArcHydro model, including HEC-GeoHMS and HEC-GeoRAS, and of course ArcHydro: http://downloads.esri.com/archydro/
Hello!
I encountered the same issue, but found a solution.
In my case I was using different versions of ArcMap (10.6.1), ArcHydroTools (10.3) and HEC GeoHMS (10.2).
That didn't matter for the previous modelling steps (Preprocessing, Project Setup, and Basin Processing,...) but for the "Characteristics" it seems to be a problem. So by using ArcMap (10.2) and reinstalling ArcHydroTools (10.2) and HecGeoHMS (10.2), I could finally use all of the tools.
Good afternoon Konstanze, how were you able to install a different version of HEC GeoHMS than your ArcMap version. I have ArcMap 10.6.1 and an unable to downgrade versions. Is there anyway of using a previous version HEC GeoHMS with ArcMap 10.6.1?
