Adequate and cost effective erosion control is an important component in most plans for reclamation of surface mined land. Despite the fact that much is known about erosion of agricultural lands, insufficient conclusive knowledge is available about erosion of reclaimed surface mined land. This study was conducted to characterize the erodibility of reclaimed surface mine land relative to unmined cropped land and to evaluate the accuracy of the universal soil loss equation in estimating erosion from reclaimed soils. A rainfall simulator was used to measure runoff and erosion rates from plots at three Indiana surface mines. The relation of erosion of the reclaimed soils was not completely constant with that from the cropped soils. Significant differences in erodibility were observed between reclaimed and nonreclaimed topsoils as well as reclaimed topsoils and reclaimed subsoils.
