CivilGEO GeoHECRAS

GeoHECRAS is a specialized engineering software developed by CivilGEO that extends the capabilities of the U.S. Army Corps of Engineers’ HEC‑RAS hydraulic modeling engine. It’s designed to make river modeling, floodplain mapping, and bridge/culvert analysis much faster and more intuitive by combining CAD, GIS, and hydraulic tools into one environment.

Core Capabilities

River & Floodplain Modeling
- Automates creation of cross sections, stream centerlines, and bank lines.
- Supports steady and unsteady flow simulations.
- Generates FEMA floodplain maps and regulatory deliverables.
Bridge & Culvert Analysis
- Simplifies modeling of roadway crossings, bridges, and culverts.
- Automatically detects roadway overtopping and flow distribution.
Dam & Levee Breach Studies
- Models dam failure scenarios and levee overtopping.
- Produces inundation maps for emergency planning.
CAD/GIS Integration
- Imports data from AutoCAD, MicroStation, ArcGIS, and Google Earth.
- Directly uses terrain models (LiDAR, DEM, TIN).
- Exports results back into CAD drawings or GIS shapefiles.
Automation & Productivity
- Batch processing of multiple scenarios.
- Automatic error checking and model validation.
- Drag‑and‑drop interface for hydraulic structures.
