HEC-RAS Software

Description

HEC-RAS is used to evaluate the impacts of floodplain encroachment (flood analysis); for example, delineating the approximate limits of the 100-year floodplain. Effects of structures such as bridges, culverts and weirs in the flood plain can be assessed.

Software Capacity

  • The HEC-RAS modeling system simulates flow through a full network of open channels, both natural and man-made.
  • The HEC-RAS modeling system develops water surface profiles (depth of flow, water surface elevation, velocity.)
  • The HEC-RAS modeling system simulates sediment transport and deposition in a stream channel.
  • Develop water surface profiles, evaluate depth of flow in stream channels, delineate floodplain and analyze flooding potential.
  • Model and analyze a network of stream channels, a dendritic system or a single river reach.
  • Model subcritical, super critical and mixed flow regimes.
  • Model sediment transport and deposition in a stream channel.
  • Model the hydraulics of bridges, culverts and stream junctions on stream flow and floodplains.
