Situation: Advances in HEC-RAS now allow for improved simulation of overbanks using 2D Flow Areas. Coupled 1D/2D models where 1D cross-sections represent the bank-to-bank cross-section data and 2D flow areas represent overbank areas has greatly improved the accuracy and robustness of HEC-RAS models. This is particularly the case in flat, urban areas with significant overbank […]
Webinar: Dam Breach Modelling Colleagues- I’m honored to join Krey Price and Bill Syme in presenting a brief webinar on dam breach modeling hosted by ICEWaRM and the Australian Water School. Half hour presentation followed by discussion and a Q&A session. Please join if you can. http://www.icewarm.com.au/australian-water-school/short-courses/course/dambreak-modelling/ A vigorous discussion with a group of highly […]
Here’s an opportunity to have a direct impact on the development of spatial precipitation and infiltration methods in HEC-RAS. Please read the message from Gary Brunner, Lead Developer of HEC-RAS, and if you would like to provide feedback to his questions, please do so in the comments section at the bottom of this post. If […]
Please join me this October for a fantastic opportunity to learn 2D HEC-RAS and Sediment Dynamics. Both courses are open to all and will be hosted by River Restoration Northwest and Portland State University. Take one or both courses! This was very popular last year and sold out so don’t wait too long to register. […]
With European teams having dominated the final rounds of this year’s World Cup, and with the World Cup having dominated European headlines for the last few months, we thought it would be a good time to highlight some of the recent HEC-RAS developments across Europe! HEC-RAS authors and developers Gary Brunner and Cameron Ackerman have […]
Are you a new HEC-RAS user? Or maybe you’ve used HEC-RAS before, but it’s been a while. Maybe you have no idea where to start. Steady or Unsteady? 1D or 2D? Subcritical or Supercritical? OK, for all you Newbies out there, I’m going to walk you through some steps to take to get you up […]
HEC has released a new version of HEC-RAS called version 5.0.5 today. This version is a bug fix only version (i.e. No new features). Unfortunately in version 5.0.4 there was a bug in which User defined Manning’s n value override regions for 2D Flow Areas (called “2D Area Manning’s n Regions”), define in the Geometry […]
If you’re in the neighborhood, or just want a nice trip to Australia, consider taking this excellent course in 1D/2D Modelling using HEC-RAS the week of 4 June, 2018, hosted by ICEWaRM and the Australian Water School. This will be a great opportunity to get some training on the new features just introduced in the […]
If anyone downloaded and installed HEC-RAS 5.0.4 before Friday May 4th at 4:00 PM pacific daylight time, please re-download and install the software.
