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
  • User Defined Rules for Controlling Gate Operations
  • Automated Calibration of Manning's n Values for Unsteady Flow
