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.
HydroCAD
HydroCAD combines the best of TR-20, TR-55, and SBUH, plus built-in hydraulics, graphics, automatic database, and on-screen routing diagram in a single program. (see comparison table) The result is the fastest, easiest, and most capable stormwater modeling system available. We call it HydroCAD because it brings the benefits of Computer Aided Design to hydrology, while not requiring any other CAD software. However, HydroCAD-10 now offers direct extraction of subarea data directly from AutoCAD®, without any other software.
