GeoHECHMS
GeoHECHMS speeds up watershed modeling by automating subbasin delineation, Curve Numbers, and Time of Concentration calculations. As an advanced data wrapper to industry-standard HEC-HMS, it simplifies workflows and accelerates common hydrologic preprocessing tasks needed for HEC-HMS modeling. Engineers use its AutoCAD-compatible interface to pull land use and soil data, compute TR 55/TR-20 parameters and simplify pre- and post-development scenarios for seamless detention/retention pond design.
GeoHECRAS
GeoHECRAS is an advanced hydraulic modeling software that simplifies HEC-RAS modeling as it accelerates river and floodplain analysis by reducing repetitive GIS and CAD processing. Tasks like merging DEMs, generating elevation profiles, or building HEC-RAS floodplain surfaces are completed in half the time. The software integrates LiDAR surveying data, NLCD Land Cover data, and FEMA Flood maps directly into AutoCAD, MicroStation, or ArcGIS workflows.
