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.
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.
