I have modeled an underground detention system utilizing a 40' x 250' area and all is fine modeling/outlet/diversion control but the reviewer is asking to demonstrate that at least 50% of the parking spaces be inundated if underground system fails. This particular system is solid storage piping (non-arch chamber and no infiltration into surrounding stone/soil).
Kind of understand the logic for asking but how to model in HydroCAD???
My thoughts:
create a pond representing the area and volume for the parking lot surface. pretty flat based on other requirements.
then route the respective post drainage basins to the surface pond peak elevation to plot.
Anyone else hear of such a request and have modeled it?
Thanks,
