HEC-RAS for river analysis
 Use HEC-RAS (3.1) for determining water surface elevations throughout a river network, and analyzing bridges and culverts.
Hydraulics
- Use the unsteady flow routing features for dam break analysis and levee breaching.
- Calculate water surface profiles based on steady, gradually varied flow for channel networks, dendritic systems, or a single river reach.
- Evaluate floodway encroachments for floodplain management and insurance studies.
- Handle rapidly varied flow conditions automatically, such as hydraulic jumps and bridge contractions.
- Include in-line weirs and gated spillways in the river system.
- Compute bridge scour based on the routines outlined in HEC-18 from the Federal Highway Administration.
- Follow the methods for low-flow computations laid out by the Federal Highway Administration using the WSPRO bridge routines.
- Analyze culverts under supercritical and mixed flow regimes, and even adverse slopes.
Output
- View the results three-dimensionally with X-Y-Z perspective plots.
- Use the built-in tables to create standard reports, including cross-section tables, bridge tables, culvert tables,
- Include the graphical river system schematic, cross-sections, profiles, and more in your final report.
