Free Webinar on Dam Breach Modeling
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. https://www.icewarm.com.au/australian-water-school/short-courses/course/dambreak-modelling/ A vigorous discussion with a group of highly […]
HEC-RAS Dam Breach course in New Zealand and Round 2 of HEC-RAS 5.0 2D courses across Australia!
Dam breach course in New Zealand and Round 2 of HEC-RAS 5.0 2D courses across Australia! We had a great turnout for our first HEC-RAS 2D course in Melbourne back in April, and I’m excited to be returning to the southern hemisphere in November to teach a 3-day HEC-RAS Dam Breach course to be […]
“Using HEC-RAS for Dam Break Studies”
HEC recently published a new training document called “Using HEC-RAS for Dam Break Studies”. Written by Gary Brunner, P.E., D.WRE, it is an easy to follow guide for performing Dam Break simulations in HEC-RAS. It covers topics like: Which routing technique to use to route flows through your reservoir (Dynamic or Level Pool-although I wish […]
Flow spike after peak of dam breach floodwave.
Just ran into an interesting phenomenon. I was running a dam breach model with fairly typical breach parameters and piping failure mode. After the peak of the breach hydrograph, there appeared a mysterious “spike” as shown in the figure below. This happens to be right at the same time the flow through the developing breach […]
Mixed Flow Regime Options – LPI Method
By using the Mixed Flow Regime option for Unsteady Flow Analysis, RAS can better handle transitions from subcritical to supercritical flow. This option should be utilized only after determining that a mixed flow situation exists, which requires judgment from the modeler. One application where this could be particularly useful is dam breach modeling, or any […]
