I'm trying to make my point versus a consultant to make sure, as a municipal engineer, that a proposed retention/sedimentation pond design will work.
For this particular design (it is), sediment control will be achieved with (read this) one (1) single orifice (diameter = 31/2'') placed at the bottom of the pond.
Consultant is telling us that the released flow will be over a long period of time...
I'm with them on this though. Even think it will be over forever or until the water evaporates of infiltrates.
What should be the minimum orifice diameter that should be specified for a sediment pond?
I know it might depend on the inflow/sediment load/debris but... from experience vs clogging issues?
