    Interestingly, the RAS release notes say “Version 6.0 of the River Analysis System (HEC-RAS) is now available. This Version supersedes Version 5.0.7, and all previous versions.” I suspect that is a little premature as we are on Beta Version 2.

    Correct. Use the beta version for testing and training, but better to wait for the official release of 6.0 before using it for a project.

    Hi Chris, I’m on the 5.0 version of HEC-RAS and I’m having trouble with my XS labels. I’m trying to create a geometry for the bathymetry but the XS labels are not in a consequential manner and thus are connecting XS that are not next to one another; creating channels where there shouldn’t be any. Any idea on why the river stations numbering are acting this way? I know the label should be the distance between the XS to the downstream of the river, but it seems my XS labels are not following this rule. Appreciate any direction you can nudge me to for a solution.

    The labels are whatever you assign them and are not tied to the actual spacing between cross sections. Unless you created them geospatially with GeoRAS or RAS Mapper. Also, if the cross sections are georeferenced, but the coordinates are wrong, they could be placed in non-sequential order. Check the coordinates of the cross section cutlines and make sure they are correct.

    Chris – I am running the Beta Version 2 to do a fairly simple analysis. I am fairly new to HecRas – so am not sure if this is a bug – or something with my model itself. Could you offer any insight on the following error message:

    Any help you can provide would be appreciated.

    The messages about the mesh property tables implies you have some 2D areas. But there’s also a message saying “Steady Flow Simulation HEC-RAS 6.0 Beta”. That implies you are running a steady flow simulation.
    You have to run 2D areas using unsteady flow.

    It seems the the stage and flow hydrograph function does not work under Beta 6. I also have problem with DSS times series plot when I specify, for example, a flow hydrograph for the upstream XS for unsteady flow. After I run the model in beta 2, but open it in v5.07, both of the above functions work.

    Thanks for letting us know! Would be good to send that to HEC as a bug report.

    HEC just released V6 Beta 3 and both of the issues have been fixed from my test run.
