Staunton 1 Reclamation Demonstration Project. Slope Angle and Erosion Rate: Final Report

摘要

At the Staunton 1 reclamation site in Illinois, data were needed for insight into the slope angles and cover material required to minimize runoff and erosion at possible future reclamation sites in the Midwest. Three replicated plots of 4 m exp 2 each were installed on each of three study slopes that ranged from 3:1 to 7:1 and that had cover material applied or that consisted of bare refuse. Runoff was collected in drums at the foot of each of the 27 plots. The runoff quantity was measured regularly and samples were analyzed for a number of parameters in the laboratory. The results of two years' testing indicate that a cover depth of more than 15 cm does not appear to be necessary; however, some cover material must be placed over the bare refuse in order to reduce runoff and improve the overall water quality.
