drainage calculations for drywell
drainage calculations for drywell
(OP)
Is there a standard way to calculate the drainage potential of a drywell given a vertical percolation rate (derived from the standard falling head test). In the past I have used just the bottom of the gravel band (gravel band usually 3' in diameter)
and also have used both the bottom of the gravel band (full area) and 1/2 of the side area of the drywell together (area times percolation rate for retention rate). Does anyone know if there is a standard method for the hydraulic analysis of drywells and or of a publication that describes the correct way to draw the flow net as applied to the drywell?
Thank you in advance,
