4_2 Hydrology Conclusion <br />• The factors are combined by simple multiplication using the RUSLE. Annual soil <br />losses for each Reclamation Unit and all 28 units combined can be compared for <br />the pre-mining and reclaimed post-mining condition. The calculation as <br />presented in Table 4 indicates that the reclaimed post-mining condition will <br />produce less soil erosion than the pre-mining condition. <br />References <br />1) Barfield, Warner and Haan, 1981, Applied Hydrology and Sedimentology for Disturbed <br />Areas <br />2) U.S. Dept.
