Detention Ponds and Time of Concentration Calculations
Detention Ponds and Time of Concentration Calculations
(OP)
How are detention ponds treated in calculating a "proposed" drainage area's time of concentration? Does the calculation include the length of flow in a pond or are ponds ignored and the calculation ends at the upstream end of a pond?
RE: Detention Ponds and Time of Concentration Calculations
This means that the Tc calculation will normally end at the inflow to the pond, and the pond routing calculation will take over at that point.
