Multiple Opening Analysis
Did you know that if you have a bridge opening and one or more culverts at a single river crossing a Multiple Opening Analysis is required?

PowerPoint Screen Record
Screen recordings are a powerful tool to help display and share animations from your RAS model. You can create screen recordings of the RAS Mapper animations that can be used to show changes in velocity, WSE, Depth, or any other mapping variables over time, instead of as a still image. There is software out there […]
The Final Version of HEC-RAS 6.0 is now available!
The FINAL release of HEC-RAS 6.0 is now available! See below message from HEC for more info. And a HUGE Congratulations to Gary Brunner for an amazing career. Thanks for all the hard work you put into making HEC-RAS such an awesome software program for us all to use. Best of luck in your retirement! […]
Lateral Structure on River Bends
Lateral structures can be used in HEC-RAS for transferring flow from a river/reach to another river/reach, 2D area or storage area. This allows the user to physically represent a variety of geometric features. In this example, lateral structures were used to capture flow overtopping high ground on the spine of a sharp river bend in […]
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 New Features – Interview with HEC-RAS Team Leader Gary Brunner (Parts 1 & 2)
HEC-RAS Friends- You do not want to miss these Full Momentum Vodcasts. In Episode 12 (Part 1), Ben and Chris interview HEC-RAS Team Leader Gary Brunner about the new spatial precipitation and 2D bridges in HEC-RAS 6.0. Plus we get into a little history of HEC-RAS as well as some special guitar talk. That’s right…Gary […]

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. […]
