HEC‑GeoRAS is an ArcGIS extension/toolbar that prepares geospatial data (terrain, cross‑sections, flow paths, floodplain polygons) for use with the U.S. Army Corps of Engineers’ HEC‑RAS hydraulic model. It converts GIS features into the geometric data HEC‑RAS needs and imports results back into GIS for mapping and analysis. hec georas for arcgis 108 upd
The HEC-GeoRAS toolbar automates the extraction of geometric attributes that would otherwise be manually intensive to create:
