New geospatial editing tools are currently in development for the next version of HEC-RAS-Version 5.1. While no date has been set for the release of Version 5.1, it is expected sometime within the next year or two. But no guarantees! This will be an exciting new addition to HEC-RAS in that users will no longer […]
The new and improved RAS Mapper interface in HEC-RAS 5.0 makes managing and exporting model results like an inundation extents shapefile or a depth grid for use outside of HEC-RAS/RAS Mapper easy. The process (which is described in detail in Chapter 5 of the HEC-RAS 5.0 2D Modeling User’s Manual) requires the user to add […]
Continuing on with the discussion on leaking in 2D meshes, I want to highlight a new feature that will be included in the full release of Version 5.0 (hopefully due out early this summer). The new feature, 2D Area Breaklines, will make aligning cell faces on to high ground features a snap! Essentially, you draw […]
There have been many questions lately about whether HEC-RAS 5.0 can perform a simulation with ONLY a 2D mesh (i.e. no cross sections). The answer is yes. In fact, in many ways it’s a lot easier. In this example, the standard Muncie project offered by the Hydrologic Engineering Center has been converted first to SI […]
