Dam Breach HEC RAS vs HEC HMS
Dam Breach HEC RAS vs HEC HMS
(OP)
I have been asked to get up to speed on dam breach analysis for permitting. Most of the work is low hazard, relatively short (under 10' high) dams. I don't have any real background in HMS or RAS. My general understanding is that HMS provides the hydrology and hydrographs, while RAS provides the analysis of structures and elevations. The question is whether the dam breach analysis that can be done in HMS is on a par with what can be done in RAS? I have a choice between HMS training and RAS training and this is the likely tie-breaker. Thanks, all.

I have used -RAS for Floodplain Modeling/BFE determination, however have not performed Dam Break Analysis before...
Based on reading thorough HEC-RAS Manual and State Guidelines, the requirements appear pretty straight forward.
Any pitfalls to look out for? (small dam Class II - Primary Spillway - 50 yr event, Total Spillway design flood 100-year event, earthen impoundment)
Thanks in advance.
