Modeling discharge questions
Modeling discharge questions
(OP)
I am modeling stormwater runoff in a quarry and want to use the ten feet of shot rock below the floor as storage for runoff. Assuming the shot floor has a limited void space (10%) for storage,what would be the best way to model the discharge to a detention basin on the quarry floor? Also, should I model the overburden above the quarry floor as one area with a Tc to the quarry floor and the quarry floor with a Tc=0, separately?
My concern is the effect that stormwater runoff from the quarry has on downstream structures. Therefore I need to begin the routing at this basin on the quarry floor.
Any ideas would be appreciated.

RE: Modeling discharge questions
Rainfall that falls directly on the surface of a pond is often modeled as a separate subcatchment with Tc=0 and CN=98. But if the pond surface is a small fraction of the total area, you could include it as a sub-area in an adjacent subcatchment.
