Assume the bottom has a surface area of 303 square feet and that runoff exfiltrates at 10 inches per hour (50% of the in-situ saturated hydraulic conductivity rate determined by field-testing). Based on the hydrograph, runoff leaves the infiltration structure at 0.07 cfs. The model calculates a storage capacity of 595 cubic feet. ................
