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.
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.
