HEC-RAS has several advanced features that can be used when modeling complex unsteady flow situations. These features include mixed flow regime capabilities (subcritical, supercritical, hydraulic jumps, and draw downs); the ability to perform a dam break analysis; levee overtopping and breaching; hinge pool calculations for navigation dams; how to model pressurized pipe flow in HEC-RAS; and using generic rules to control gate operations at hydraulic structures.
The advanced features discussed in this section are list below.
- Mixed Flow Regime
- Dam Break Analysis
- Levee Breaching and Overtopping
- Pump Stations
- Navigation Dams
- Modeling Pressurized Pipe Flow
