HEC-GeoHMS: Importing HEC-GeoHMS Toolbox

PeterWilson — Fri, 10 Dec 2021 23:34:52 GMT

I need assistance in importing HEC-GeoHMS Toolbox into Python. I haven't been able to find any examples of the correct syntax to import and use the tools within the HEC-GeoHMS Toolbox. The code below is based on export a model from ModelBuilder with one of the HEC-GeoHMS tools within it. It keeps telling me that there are no arguments. Any help will be appreciated.

# determine the centroidal longest flowpath
arcpy.AddMessage("Processing Centroidal Longest Flowpath")
arcpy.CentroidalLongestFlowpath_geohms(Subbasin, Centroid, LongestFlowPath, Output_Centroidal_Longest_Flow_Path) #@UndefinedVariable

The error message that I receive is attached below:

Hi Thomas, Unfortunately not. I kept getting error messages. Not sure if ESRI\USACE have added python support to HEC-GeoRAS. GeoRAS might not be supported in HEC-RAS 5 as they are building their own GIS functionality directly into HEC-RAS to mitigate the need for HEC-GeoRAS.
