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.
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.
