Webinfluence the rate of infiltration for the facility, consider soil layers at greater depths when assessing the site’s saturated hydraulic conductivity characteristics. Massmann (2003) indicates that where the water table is deep, soil or rock strata up to 100 feet below an infiltration facility can influence the rate of infiltration. WebTypically, this parameter is equated with the saturated hydraulic conductivity of the soil. The SCS (1986) classified soils on the basis of this infiltration capacity, and Skaggs and Khaleel (1982) have published estimates of infiltration rates for those soils, as shown in the following table.
