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.
GeoSTORM
GeoSTORM is a Civil 3D-integrated stormwater modeling software that streamlines catchment area delineation, runoff calculations, and flow routing. It supports multiple hydrology methods, such as EPA SWMM, SCS TR-55/TR-20, Rational, Modified Rational, and DeKalb Rational, enabling flexible hydrologic analysis. Capabilities include interactive detention/retention pond design and roadway catch basin optimization using major U.S. and Canadian foundry catalogs, which helps engineers move from concept to deliverable efficiently.
