***Note.  If you originally downloaded 5.0.4 before May 4 at 4:00 pm PDT then please redownload and install from the links below.  There were some minor errors found in the original release.

Download HEC-RAS Version 5.0.4 here:

From HEC:
We have released the final version of HEC-RAS 5.0.4 today.  It is now available for download from our webpage at the link below.  I have enclosed the 5.0.4 release notes for your review.  I have also included a separate document that describes how to use the new features contained in this version. Additionally  I have also included a document on how to spec out a computer for doing 2D modeling with HEC-RAS.

            We hope you enjoy the new version of the software.  As always, please keep us informed on any bugs you find, or your ideas for new features.  Here is the link to the HEC-RAS 5.0.4 web page:


            The following is a list of the major new features you can read about in the Release Notes and the Supplemental User’s Manual:

  1. New RAS Mapper Pre-Processor Tools
  2. Variable Time Step Capabilities (improved accuracy and faster run times)
  3. Increased Computational Speed for 2D Computations (2 to 5 times faster run times)
  4. Enhancements to SA/2D Hydraulic Connections
  5. New 2D Polygon Mesh Refinement Tool
  6. Internal Boundary Condition Lines for 2D Areas
  7. New Velocity Term for 2D Flow Area Boundary Conditions
  8. 64–bit Version of RAS Mapper and 64-bit 2D Pre-Processor (RAS now can handle much larger 2D models)
  9. Improved Terrain Generation Utility
  10. Improved Manning’s n Layer Development
  11. Sediment – New Options in the User Defined Grain Class Editor
  12. Sediment – New Transport Function Calibration Options

WARNING: Some of the bug fixes “may” cause the computed results from 5.0.3 to 5.0.4 to change.  Please read the Release Notes carefully for information about these changes.


There are two new verification and validation documents for HEC-RAS now available on our web page in the HEC-RAS area.  Here is a short description of each:


  1. RD-52  HEC-RAS Verification and Validation Tests (Enclosed in this email)

            This is the first ever full blown Verification and Validation document for HEC-RAS.  In this report we compare HEC-RAS to: analytical and text book data sets; lab studies, and real world flood events with good observed data.  This report covers 1D steady flow; 1D unsteady flow, and 2D unsteady flow computations.  The report verifies that HEC-RAS correctly solves the equations used in each of these computational frameworks, and it verifies that HEC-RAS can be used for a very wide range of riverine modeling conditions.  It can aslo be download here:



  1. RD-51 Benchmarking of the HEC-RAS Two-Dimensional Hydraulic Modeling Capabilities

This research document summarizes how the Hydrologic Engineering Center's (HEC) River Analysis System (HEC-RAS) software performed in the two-dimensional (2D) modeling benchmark tests developed by the United Kingdom's (UK) Joint Defra (Department for Environmental Food and Rural Affairs) Environment Agency.  This is an updated version of this report that we previously developed.  We re-ran all of the test, plus one new test, with version 5.0.4 of HEC-RAS.  The results are even better than before, and the HEC-RAS computational speed is much faster than previously document.  This report can be downloaded from our web page at the following link:

  2. After downloading, I think that we have to desinstall the "old" one and then reinstall the "new one" ? Right ?

    2. Dear all, Do any one face with difficulties to open HECRAS Ras-mapper wizard in the new version of 5.0.4?

      Thanks

    3. Dear Habtom, It happens the very same thing with my laptop running on Windows 8. RasMapper simply just does not react. Problems with the "Microsoft .NET Framework 4.7.1 Full" may be? Don't know.

  3. Dear HECRAS users I download the new vesrion HECRAS 5.0.4, but while try to open the RasMapper wizard its not open, anyone who knows how to fix this thing please share me your idea.

    Thanks

    1. Not me. I've used it on 2 different Windows 10 computers without problems.

    2. I have the same problem on win7 64-bit computer. But on the win8.1 64-bit computer RasMapper works fine.

      I start HEC-RAS, but RasMapper window doesn't open. The previous version works fine. Maybe new RasMapper requires some libraries which win7 doesn't have?

    3. Hello Chris. I'm Alberto from Chile (UCSC Class). I have the same problem, because I can not open RAS MAPPER on Windows 7 computers. I have tried it with three PCs and I have the same problem.

    4. Sounds like 5.0.4 has some bugs. If you can get a Windows 10 machine, try it there. Otherwise, you may be stuck with the older RAS version until they fix it.

    5. I have the same problem on windows7 32 bit machine. Does anyone have any ideas? Tks

  4. Dear, I think Ras mapper of version 5.0.4 HECRAS, has some difficulties to open the wizard at windows 7 computer, if there is any solution for that please let me know.
    Thanks in advance.

    2. RAS Mapper in 5.0.4 is now exclusively 64 bit. So if you have a 32 bit computer you’ll unfortunately have to use 5.0.3

  5. I'm using this new version for flood mapping, but I'm having a hard time of importing the breaklines shapefile to the 2D flow area since the Breaklines Coordinate Table under the Breakline of GIS Tools is not yet activated unless i will draw a breakline for it to activate.

    Hope you can address this question.

    Thanks in advance.

  6. I built a 2D model in RAS 5.0.3 and run well. For test purpose, I open the model in Beta RAS 5.0.4, and the model run fine. However, as I open the model in RAS 5.0.4, the geo, flow and plan files look fine. when I start running the model, it gave an error "Mesh '2Darea' was not created successfully". I went back to geometry editor of 2D area, when i start moving points, it gave "Unknown error: Arithmetic operation resulted in an overflow"; I move a 2d cell point for test, it gave "3 face errors detected on the perimeter of the mesh" which i couldn't identify where the errors are like it was shown as red dot in 5.03 and beta 5.04. As i pan around, the number of errors keep changing but not shown in the editor window. Has anybody seen this error before? Thanks for any help!

  7. Is there an option to perform sediment transport in HEC-RAS 2D yet? I thought that was going to be an option on the new version.

    1. No. Not yet. It’s probably a few years out still.

  8. I am reading HEC-WAT user manual now. In bench mark 5 it is presented about computational interval. In the manual we can not see much effect from computational interval there. But in my case WSE and velocity change when I change the computational interval n considerable amount while I was using HEC 5.0.3. How to select a reasonable computational interval?

  9. hec ras automatically close do you have any solution for this?

    1. Have your à 64 bits system or only 32 bits system ? The new RASMapper release work on 64 bits system.

  10. I would like to know if there is a standard overall accuracy for the flood maps generated using HECRAS or the USGS set a standard for the overall accuracy of the flood maps generated using HECRAS. What must be the minimum values of the overall accuracy for flood maps? I will be glad if someone can send me an RRL regarding this one because I've been searching it and i have still nothing to find.

  11. After a successful run of HEC-RAS 5.04, the Depth, Velocity and WSE layers do not appear on the RAS Mapper screen even though they are written in the results tab of the RAS Mapper window. Can anyone help on this?
