H&H Essentials 2: Steady vs. Unsteady HEC-RAS Example

Excerpt #2 taken from our online Hydrology and Hydraulics Essentials course series. In this lecture, we start with the model developed from scratch in our previous video (   • H&H Essentials 1: 1D vs. 2D with a rooftop...  ) and highlight the conceptual differences between steady and unsteady modelling approaches, including the extreme differences in simulation and run times: In this case, an unsteady model that would take over a year of run time runs in less than one second as a steady flow model.
