“Flow or Temp time series date is not sufficient to run requested time window.” This one has been around for a while, but it just showed up again on the Facebook HEC-RAS User’s Group, so I thought I’d show the fix(es) here. This applies to the new beta version of 5.0, as well as previous […]
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 […]

Hi HEC-RAS users. HEC is extremely busy dealing with bugs and questions at the moment. They’re currently working mostly to fulfill their obligations for technical support to the Corps of Engineers only. If you are trying out the new version 5.0 beta, and you discover a bug, or if you simply have a comment or […]
Hey 5.0 Beta users. Please get a new copy of HEC-RAS 5.0 Beta. It has some of the early problems already fixed. See below for instructions and have fun.

Latest October 2014 beta version is available here: http://hecrasmodel.blogspot.com/2014/10/updated-hec-ras-version-50-beta-now.html Dear HEC-RAS 5.0 Beta (with 2D) tester, You […]
A few testers have discovered a dll conflict when trying to open the new 5.0 beta version of HEC-RAS. The following message appears: This happens if you’ve installed the HDF5 Viewer as described in the new “Combined 1D and 2D Modeling with HEC-RAS” document on page 115. HDF5 is a new file format used by […]
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, […]
