CivilGEO GeoHECRAS , developed by CivilGEO, is a civil engineering software that enhances the U.S. Army Corps of Engineers’ HEC-RAS program with an interactive 2D/3D graphical user interface. Released on July 7, 2020, it integrates with AutoCAD, Bentley MicroStation, and ESRI ArcGIS, streamlining workflows for hydraulic modeling, floodplain mapping, and infrastructure design. Key features include:
- Enhanced Modeling: Supports 1D and 2D steady and unsteady flow computations, bridge and culvert design, flood inundation mapping, and river restoration. It pulls data from various sources like CAD files, GIS data, and digital elevation models (DEMs) for rapid HEC-RAS model creation.
- Visualization: Offers 2D/3D visualization with georeferenced maps (e.g., Google Maps, Bing Maps), allowing users to layer FEMA flood maps or export to Google Earth.
- Data Integration: Seamlessly imports and processes AutoCAD, MicroStation, and ArcGIS data, including survey points, LiDAR, and TINs, for accurate cross-section extraction and terrain modeling.
- Automation: Features automated engineering report generation in Microsoft Word/Excel and tools like the Scenario Manager for comparing design alternatives.
- Licensing: Utilizes FlexNet licensing technology from Flexera for improved usability.
- Applications: Used for floodplain analysis, dam breach modeling, and stormwater management, with case studies like flood mapping for the Colorado River during Hurricane Harvey.
