Parking Lot Inlet Ponding
Parking Lot Inlet Ponding
(OP)
I'm looking to analyze the depth of ponding (for a 3-yr & 100-yr storm event) at each grate inlet for a parking lot storm sewer system -I'd appreciate any input on the best way to do this without using a for fee software program -thanks.

Q cfs = 3.0(PH^3/2)
P = permiter of the grate (ignoring bars)
H = head over grate
this can only be used for h=0.4 or less
If it is not a combination inlet them multiply by 75% to account for clogging
this assumes that the total discharge can enter the system for the design storm ...
others an hgl will have to be run and a routing program (100-year storm)
