subsurface detention
subsurface detention
(OP)
I would like to model subsurface detention basin (crushed stone layer) under a parking lot that is sloped. There are a number of inlets through pervious pavement into the layer, so I thinnk they should be multiple Ponds. I added low (6" high) dams below each inlet, so that the infiltration will contact the maximum subsurface area. How can I model the flow over those subsurface dams in the crushed stone layer? It seems that sharp crested weir is not approporiate due to the stone/void ratio. Sharp crested weirs require open air, right? How would you recommend modeling the flow over the buried weirs?

The oscillations definitely need to be resolved. There are a number of possible causes. Check ALL your warning messages. If you still have questions you can post your file or sent it to HydroCAD support.
