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 […]
(Initial post 19 Feb., 2015. Updated 20 Feb., 2015). I continue to be more and more impressed with how user-friendly and robust the new 2D feature is in HEC-RAS. However, there are some issues to be aware of, particularly in how results are mapped. I want to take the next two blog posts to highlight […]

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 […]
Let’s say you have a digital terrain model of the area you want to model with 2D HEC-RAS. ONLY 2D RAS. In other words, you want to lay out a grid, but do not want to have do to any 1D computations-all 2D. The problem is the area you want to model includes one or […]
Check out this great RAS2D presentation that Kevin Denn gave at the NHEC Conference last week.
***Note-this post was for the old 5.0 beta version. Please get the latest version here: http://hecrasmodel.blogspot.com/2014/10/updated-hec-ras-version-50-beta-now.html Hey RAS Modelers-The long awaited HEC-RAS Version 5.0 with 2D Modeling is finally out in beta form! Please read the message below from Gary Brunner that provides instructions for downloading and installing HEC-RAS 5.0 beta. Please note that there is a […]
UPDATE. HEC has asked that I no longer distribute HEC-RAS 4.2 with 2D Alpha. Their purpose for releasing this alpha version is to get constructive feedback so that they can improve its functionality and efficiency; and to minimize bugs before the offical beta release-not to be critically compared to other established 2D software packages…yet. So far, […]
