French Drain Flow Rates
French Drain Flow Rates
(OP)
I'm looking for typical flow rates through a french drain with perforated pipe in it. Say 1' x 1' cross section. Does anyone have data or knows where I can get such data?
Also, does anyone know of any alternates to gather flow sub surface?

I am doing a comparison for drainage systems under sports fields and I want to do is a comparative analysis of different systems based on maximum drainage rates.
The flow rates I'm looking for would be for a rock filled trench wrapped in a non-woven geotextile with the dimensions from my original post. Slope would be around 1% with no water table. I need an estimate only on what the maximum flow rate that the french drain would be capable of handling.
