HEC-RAS 5.0 now provides a tool for quickly re-projecting model geometry within RAS. It is accessible from the main RAS interface under the Options menu…Convert Horizontal Coordinate Systems. From this window, the user must select the Current Project Spatial Reference System and the Destination Project Spatial Reference System by loading the appropriate projection file (*.prj) […]
HEC has just released an updated beta version of HEC-RAS 5.0. This is the third and final beta release before the final release due out in January 2015. This new release takes care of most of the bugs that have been reported and includes some nice new features like spatially varying Manning’s n values for […]
(Update: New release is now available here) Just heard from HEC that a new, updated beta version of HEC-RAS 5.0 will be coming out soon (later this month or early next). The full release of HEC-RAS Version 5.0 is still scheduled for the end of the calendar year. New features in the next beta release […]
Your computational mesh is what will allow you to do 2D modeling in HEC-RAS. Think of a mesh as a net that you drape over your terrain. The continuous properties of the “infinite” terrain are then discretized onto the mesh so that computations can be made over a finite domain. Here in the geometry editor, […]
There are a lot of new features in Version 5.0. We’ve discussed quite a bit the new two-dimensional capabilities. But a real pleasant surprise for me was how great the new RAS Mapper is. I’m going to try to highlight some of these new Mapper features over the next few months, but in this post […]

For all you sediment transport enthusiasts, Marty Teal is giving this webinar in October. I highly recommend it. He has a wealth of experience in sediment transport modeling and is an excellent instructor. Go sign up if you want to learn more about sediment transport modeling in HEC-RAS!-Chris G.@RASModel ASCE Continuing Education and ASCE’s Environmental […]
Check out this great RAS2D presentation that Kevin Denn gave at the NHEC Conference last week.
Many water surface profile software programs prior to HEC-RAS had a quirky rule against having perfect vertical sides. In other words, you could not have two or more elevations at the same stationing. A perfect example of this is a rectangular flume. The workaround for the older software was to define the tops of the […]
Here’s a nice feature in HEC-RAS input tables that will save you a little bit of time. Let’s say you want to highlight an entire column of data. Maybe you want to delete all of the values in that column or paste in a block of data. Or perhaps you want to highlight all of […]
