Product Overview

HEC-RAS

Description: HEC-RAS is hydraulic modeling software used to perform one-dimensional hydraulic calculations for natural and constructed channels. It is commonly used for floodplain mapping, flood damage reduction studies, and flood risk management.

GeoHECRAS

Description: GeoHECRAS is a geographic information system (GIS) integrated with HEC-RAS hydraulic modeling software. It allows users to display, manage, analyze and visualize spatial data related to river systems and run hydraulic simulations.
