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. The software supports multiple rainfall distributions and routing methods, such as Muskingum, Kinematic Wave, Modified Puls, and Snyder Unit Hydrograph. Both US and metric (SI) units are supported, making GeoHECHMS a powerful solution for accurate watershed modeling and hydrologic analysis.
