As most HEC-RAS users quickly find out, there are some convenient tools for managing your view in an HEC-RAS graphic. Zoom In, Zoom Previous, Zoom Out, Full Plot, and Pan. These generally work how you think they should and are available on all of the HEC-RAS graphics including the geometry schematic, profile plots, cross section […]
Ahead of the wide-scale implementation of the 2-dimensional (2-D) modeling module in HEC-RAS, I wanted to share a quick tip that will be useful for editing your 1-dimensional (1-D) HEC-RAS model to prepare to couple your 1-D channel with a 2-D overbank area. It’s common to have a cross section with a well-defined channel and […]
Have you ever looked at your profile plot from an unsteady flow model and found “walls of water” on top of your bridge? Or just unexplained unrealistically large amounts of energy loss over a bridge? Take this for example: Notice the three large “steps” in energy grade line (and water surface elevation). It’s hard to […]
