HEC-RAS Tutorials
Master the River Analysis System (HEC-RAS) with our comprehensive tutorial series. From basic 1D modeling to advanced 2D hydraulics and dam breach analysis.
What is HEC-RAS?
The River Analysis System (HEC-RAS) is a free, industry-standard software package developed by the U.S. Army Corps of Engineers (USACE). It is the most widely used hydraulic modeling software for river and floodplain analysis in the world.
- 1D steady and unsteady flow water surface profiles
- 2D flow modeling for complex floodplains
- Sediment transport and mobile bed modeling
- Water quality and temperature analysis
