Storm Drain Inlet Blow-by
Storm Drain Inlet Blow-by
(OP)
Does anyone know of a good source (book or software) that can calculate the volume of water which "blows by" the storm drain inlet? I am interested in varying upstream gutter geometry and inlet opening geometry to optimize (minimize) that volume of water.

summarizes a method I have never seen rejected by any reviewing engineer. Pages 22-35 details all equations you need to create a spreadsheet to do this. Composite gutter cross sections are included, which I think is what you are looking at.
There is also a free software download available, but it had no tech manual with it when I looked at it (years ago, that may have changed); so I did not know where the numbers where coming from, so I didn't feel comfortable using it blindly.
