HEC-GeoRAS is a GIS extension that provides the user with a set of procedures, tools, and utilities for the preparation of GIS data for import into HEC-RAS and generation of GIS data from RAS output. While the
GeoRAS extension is designed for users with limited geographic information systems (GIS) experience, knowledge of GIS is advantageous. Users, however, must have experience modeling with HEC-RAS and have a
thorough understanding of river hydraulics to properly create and interpret GIS data sets.
Notice
The HEC-GeoRAS downloads available from this webpage were tested, verified, and are supported by HEC. HEC-GeoRAS Version 10.2 is the last version that was tested and verified to be functional in ArcGIS 10.2.1
and is available from this webpage. HEC will no longer test and verify newer versions of HEC-GeoRAS that is compatible with versions of ArcGIS that are newer than Version 10.2.1. Newer versions of HEC-GeoRAS
have been made available from the ESRI FTP site; however, these newer versions have not been tested nor will they be supported by HEC. HEC is developing the necessary GIS capabilities directly within HEC-RAS.
HEC-RAS Version 5.0 contains the results mapping capabilities in HEC-GeoRAS Version 10.2, and HEC-RAS Version 5.0.4 will contain geometric preprocessing capabilities. HEC-RAS Version 5.0.4 should be available
in the Spring of 2018.
