Calculate Total Volume V10 <br />V10 = 0.14 in. x 1 ft. x 91.6 acres <br />12 in. <br />V10 = 1.07 ac.-f t. <br />(46,683 ft.3) <br />2. Sediment Volume (Ys) <br />Universal Soil Loss Equation (LISLE) <br />A = RKLSCP R = 30 C = 0.10 <br />K = 0.39 P = 0.50 <br />• LS = 0.47 <br />A = (30) (0.39) (0.47) (0.10) (0.50) <br />A = 0.275 tons/acre-year <br />Calculate Vs based on 3 yrs, sediment storage <br />Assume: Bulk Density = 80 lbs/f t.3 <br />Vs = 91.6 ac. x 0.275 tons/ac-yr x 3 yr. x 2000 lbs/~n <br />Vs = 1889 ft3 (= 0.043 ac-ft) 80 lb/ft <br />.
