vegetation data along with slope measurements comparing the Bond Release Block and associated <br /> reference areas. <br /> RUSLE was used to calculate predicted annual sediment erosion in tons/acre/year based on the <br /> equation: <br /> A(soil loss in tons/acre/year) = R*K*L*S*C*P <br /> Where: A = predicted erosion in tons/acre/year <br /> R = erosivity index of local rainfall <br /> K = soil erodibility actor <br /> LS = length/slope factor <br /> C = vegetative cover factor <br /> P = management practice factor <br /> Representative slopes for the Phase II Bond Release Block and associated reference areas were <br /> selected to calculate predicted soil loss in in tons/acre/year. For this analysis, no adjustment was <br /> made for sediment delivery ratio Rather it has been conservatively assumed that all soil eroded off the <br /> natural surface or the reclaimed mine areas would eventually report to receiving streams even though <br /> it is likely that some sediment will become trapped on site before reaching a stream. The following <br /> discussion provides the basis for selection of each factor. <br /> 9 <br />
