In today’s video, we’re talking about computational hydraulic river modeling. HEC-RAS is ubiquitous in the industry, and many H&H engineers in the U.S. use it regularly for various applications including floodplain mapping, reservoir simulations, breach analysis of dams, and even fluvial geomorphology. Water resources engineers are very fortunate that many of the most-used software packages are available for free. I prepared a rudimentary model of the Kasei Valles on Mars to demonstrate RAS's capibilities. It's not scientifically rigorous in any way, but it provides some nice visualizations that illustrate why engineers use computation hydraulic river models. Please excuse my unkempt mug. We celebrate Movember at work, and I am getting a bit more growth before I go down to just the mustache :) Thanks to Trent Hare and Moses Milazzo from the USGS Astrogeology Science Center for their advice and help with the Mars terrain data.
