GeoHECRAS

GeoHECRAS is a hydraulic modelling interface from CivilGEO that runs above the HEC-RAS and HEC-HMS engines. Engineers use it to build and review flood and stormwater models by working graphically on a map instead of editing input files.

What GeoHECRAS offers

• Map-based modelling — work on the model directly over Google Maps and aerial imagery.
• Model construction — build 1D and 2D HEC-RAS models from several data sources.
• Hydraulic analysis — water surface profiles, bridge and culvert crossings, floodplain encroachments, stream restoration and storage areas.
• CAD and GIS links — integrates with AutoCAD, Bentley MicroStation and ESRI ArcGIS.
• Sibling tools — CivilGEO also sells GeoHECHMS and GeoSTORM for related hydrology work.

Who it works with

CivilGEO describes its users as civil and water resources engineers, and says more than 2,500 companies worldwide use its products.
