HydroCAD Piping Failure and dam breach analysis
HydroCAD Piping Failure and dam breach analysis
(OP)
Good evening. I am doing a dam breach analysis on a small earthen berm farm pond. Very shallow and very old with a long shallow approach to the weir. The regulator is asking that I model a sunny day breach (as would be typical) by piping failure. I have modeled the breach using 150% of the 100 year rainfall event in HydroCAD and the results is a class A hazard dam. Despite this the regulator still wants to see the sunny day model with piping. Given the scope of the project I would rather not model it with HEC software as I am not really familiar with it. I am competent in HydroCAD. I'm hoping that someone can point in the direction of a method for modeling a piping failure. Thanks!

Modeling a "piping failure" would be somewhat different. That really isn't a dam breach. If you can explain exactly what you're trying to model perhaps I can be of more assistance.

I would like to be able to model a progressive failure which begins with a seepage pipe. Essentially seepage and weeping progressing to a trapezoidal failure from the bottom up.
I hope that made it a bit more clear.
Thanks for your help.
