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 […]
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. […]
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 […]
HEC-RAS Pub & Grub 2020 recap. A review of the 2020 HEC-RAS Pub & Grub Event that took place at the Craft Brew Alliance's pH Experiment pub in Portland Oregon Feb 20, 2020.
HEC-RAS…Portland…Food…Beer. They seem to just go perfectly together. That is why we’re hosting… HEC-RAS Pub & Grub 2 You will want to save this date! On Feb 20, 2020 HEC’s very own Gary Brunner, Cameron Ackerman, and Mark Jensen will be joining me in Portland Oregon to speak at the next offering of the HEC-RAS […]
RAS Users: Please give this “Known Issues” report a read if you’re using Version 5.0.6. If you’ve been doing a lot of 2D modeling, it’s likely you have been affected by some of these. This link includes a document of “Known Issues” found in version 5.0.6 of HEC-RAS to date. The document outlines all of […]
One of the most anticipated new features soon to come in the next major version of HEC-RAS (Version 5.1) is the option of running unsteady 1D reaches with a finite volume solution scheme. This will be a fantastic addition to HEC-RAS. Gary Brunner recently gave me a brief overview of the new finite volume feature […]
In case you haven’t seen it, there has been a very popular LinkedIn discussion on the Hydraulic/Hydrologic Modeler’s Forum debating the advantages, disadvantages, and merits of HEC-RAS 5.0, TUFLOW, and DHI’s MIKE21. There was a lot of great information (and some misinformation) and insight provided in that thread. It is well worth the read. Some […]
In advance of the final release of Version 5.0 (hoping for this summer), HEC has released its 2D Modeling User’s Manual, written by Gary Brunner, the HEC-RAS Team Leader. This manual contains updates to all of the information that was put out in the previous guidance document, “Combined 1D and 2D Modeling using HEC-RAS” as […]
