HEC-RAS 6.0 beta 2 is now available!

The beta 2 release of HEC-RAS 6.0 is now available. This fixes the bug with 2D bridges in SI models. See below message from HEC for more info:   We have released another beta version, which is now available from our website. Several bugs have been fixed from the previous version. I have enclosed a […]

HEC-RAS 6.0 beta is now available!

RAS Users!  Go get your copy of HEC-RAS 6.0 beta.  It’s now available!!! I’ve had the opportunity to test drive the new 2D bridge feature and it is AWESOME!  Very easy to use and finally gives us the ability to model bridges in 2D!!!  HEC will also make available some data sets to demonstrate how […]

Steady Unsteady? 1D, 2D, 3D? Modeler Application Guidance

Hey RAS Users.  HEC just put out this very informative document that helps and guides the modeler with the decision between building a steady versus unsteady model, as well as when to go with a 1D, 2D, or 3D model. Modeler Application Guidance for Steady vs Unsteady, and 1D vs 2D vs 3D Hydraulic Modeling. […]

HEC-RAS Subgrid Bathymetry Theory and Application

Mark Forest is one of the most knowledgeable H&H modelers I know.  He’s also a very experienced RAS modeler.  Here he discusses the benefits of the relatively unique subgrid bathymetric approach to terrain surface discretization that HEC-RAS uses, specifically on the topic of computational mesh cell size.  Read this.  Then read it again.  This is […]

Very fine 2D Modeling

I’m a big fan of testing HEC-RAS to the limits.  What can it do?  What can’t it do?  These are questions we should all ask at the beginning of a project.  Can HEC-RAS actually prove to be a useful tool in answering hydraulic-related questions for our specific problem?  Shortly after coming to work at Kleinschmidt […]
