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 () 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. Additional H&H topics are listed here on the course series registration page:
