A study was conducted to determine erodibilities of different reclamation treatments and an unmined soil at three Indiana strip mine sites. A rainfall simulator was used to artificially erode plots constructed within seven treatment categories and the unmined soil. Soil erodibility was assessed in terms of the universal soil loss equation (usle) k factor. Values for k calculated from field data were compared with values predicted from independently measured soil properties. Differences in soil erodibility between treatments were site specific. Unmined soil had the highest calculated erodibility at one site, but at two other sites soils having reclaimed a horizons were highest. Shaley overburden treatments had the lowest calculated erodibility. Predicted soil erodibility was usually lower than that calculated from field data. Site specific slope gradient factors were developed for reclaimed a horizon treatments.
