Mixed Flow Option in HEC-RAS Unsteady Flow Modeling

Unsteady flow modeling is often fretted with instability issues. This is especially true when modeling mixed flow in an unsteady flow model due to the complexity of modeling a mixed flow regime (subcritical, supercritical, and hydraulic jumps). This complexity is associated with the nature of the unsteady flow equations (St. Venant equations). The St. Venant … Read more
