What is GeoHECRAS?
GeoHECRAS significantly speeds up HEC-RAS model creation and review, producing better and more accurate results. Compute water surface profiles for steady and unsteady flow models, bridge and culvert roadway crossings, FEMA floodplain encroachments, stream restorations, inline reservoir structures, off-channel storage areas, and much more.
- Easy to Learn and Use
- Work Directly on the Map
- CAD & GIS Integration
Work Faster with Automated Workflows
AutoCAD, MicroStation & ESRI ArcGIS compatible graphical interface to HEC‑RAS
GeoHECRAS is an AutoCAD, MicroStation and ESRI ArcGIS compatible interactive 2D/3D graphical user interface data wrapper to the US Army Corps of Engineers HEC-RAS software.
Import a variety of different data quickly and easily into HEC‑RAS
Import existing Army Corps HEC-RAS models and quickly georeference them to real-world maps using included georeferencing tools.
Work simultaneously on multiple HEC‑RAS models
Work with multiple HEC-RAS projects simultaneously using the Multiple Document Interface (MDI), including copying and pasting of cross sections and other data between HEC-RAS projects.
CAD & GIS Integration
Integrate HEC-RAS directly with AutoCAD drawing files, Bentley MicroStation drawing files and ESRI ArcGIS map data.
2D & 3D Viewing and Editing
Shift seamlessly between 2D and 3D viewing perspectives to more clearly identify modeling issues and make changes.
Work Directly on the Map
Blend Google or Bing online maps and high-resolution aerial imagery files
directly into the HEC-RAS model.
Digital Terrain Cross Section Cutting
Extract HEC-RAS cross sections from 3D digital elevation terrain data.
Floodplain and Floodway Mapping
Generate floodplain and floodway mapping from HEC-RAS results and 3D
digital elevation terrain data.
2D Mesh Generation and Refinement
Create either rectangular or adaptive meshes, depending upon the project
