I've realised most information is on earth dams. We have been tasked, as students, to perform three dam break analysis. I have read that overtopping is unlikely to cause a concrete arch dam to fail so in HEC-RAS that leaves us with failure due to piping. How would one analyse failure due to erosion of the foundation/abutment, abutment sliding or seepage? Also is it correct to use a 2D mesh for the reservoir as well as the flow of water downstream while the dam is a '2D Area Connection' and the inlet and outlet 'SA/2D Area BC Lines', therefore I wouldn't have to use a mix of 1D and 2D?Anonymoushttps://www.blogger.com/profile/08122445934627668443noreply@blogger.comtag:blogger.com,1999:blog-1675184707067447729.post-52428803584034938202019-04-02T15:11:44.669-07:002019-04-02T15:11:44.669-07:00Not as of the latest version.

I would like to ask if there was any modification in the HEC RAS to allow to model a viscous slurry since the publication of your answer?<br /><br />I was asked the same question of the post, if it is possible to model the breach of a coal slurry impoundment and until now, I have only found this possible using openFOAM.

Perhaps your location prevents you from downloading from a US Gov't website (some countries are not allowed, i.e. Iran). <br /><br />The HEC-RAS manuals have brief write-ups on dam breach modeling, and you can find some information on this blog. Otherwise, I don't know of any tutorials.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1675184707067447729.post-64939788379254134002011-09-28T02:35:03.983-07:002011-09-28T02:35:03.983-07:00Dear Chris
