Welcome to RiverGIS!

RiverGIS is a QGIS plugin for creating HEC-RAS flow model geometry from spatial data. The functionality is similar to that of HEC-GeoRAS. For data store and spatial operations it needs a PostGIS database.

RiverGIS is free/libre software and is released under the GNU General Public License. Browse the source code on github.
