FOOTHILL SANITARY LANDFILL <br /> Soil Loss Computation Using The Universal Soil Loss Equation <br /> USE <br /> 2 Ton/Acre/Year is considered an allowable soil loss <br /> according to the EPA Guideline Manual For Landfill Design, <br /> Liner Systems And Final Cover, July 1982 . <br /> UNIVERSAL SOIL LOSS EQUATION <br /> The soil loss equation provides a method for computation of <br /> soil loss. It empirically determines a loss per acre based <br /> on factors from tables multiplied together. The tables are <br /> on the following page. <br /> SOIL LOSS <br /> Five conditions or parameters are used to compute the soil <br /> loss load and the factors to use corresponding to those <br /> conditions. The conditions are as follows: <br /> 1. Maximum overland slope distance in meters and the <br /> average surface slope are used to determine the <br /> value for S. Maximum distance = 800M; average <br /> surface slope = 6%. <br /> S = 3 . 6 (extrapolated from table) <br /> 2 . Soil type and percent organic matter are used to <br /> determine the soil texture (K) . Soil type = loamy <br /> sand; organic content = 3%. <br /> K = 0. 12 (table) <br /> 3 . Land use and amount of cover are used to determine <br /> the residue cover (C) . Land use = managed pasture; <br /> amount of cover = 1/4 . <br /> C = 0. 05 (table) <br /> 4 . Percent slope and erosion-control practice are used <br /> to determine the value for P. Percent slope = 6%; <br /> Erosion control practice = straight up hills. <br /> P = 1 (table) <br />
