GeoHECRAS

357 reviews

GeoHECRAS is an advanced hydraulic modeling software that simplifies HEC-RAS modeling as it accelerates river and floodplain analysis by reducing repetitive GIS and CAD processing. Tasks like merging DEMs, generating elevation profiles, or building HEC-RAS floodplain surfaces are completed in half the time. The software integrates LiDAR surveying data, NLCD Land Cover data, and FEMA Flood maps directly into AutoCAD, MicroStation, or ArcGIS workflows. GeoHECRAS is used for river modeling, 1D and 2D hydraulic modeling, dam breach analysis, and HEC-RAS bridge modeling, along with complex floodplain encroachment studies—all with built-in reporting and reduced external GIS dependency.

GeoHECHMS

127 reviews

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. 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.

GeoSTORM

49 reviews

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. Additional features include cloud-based mapping, 2D/3D model visualization, and in-depth automated report generation. GeoSTORM is engineered for both urban and rural stormwater drainage systems, supports scenario comparisons, and accelerates design review and iteration, making stormwater workflows faster and easier to maintain.
