Examination of natural watersheds will show that the drainage networks and slopes are relatively fixed. Those forces giving rise to channel development (rate of runoff and hillside slope) will be in dynamic equilibrium with forces resisting erosion (primarily soil shear strength). When in an equilibrium condition, channel erosion is minimized with sediment yield originating primarily from splash and sheet erosion. A study of three strip mine sites in Boone, Randolph and Macon Counties, Missouri, indicated that reclaimed mine land, even when graded to acceptable specification, is left with an extremely high potential for erosion and sediment yield. Compliance with reclamation law apparently caused grading practices which created convex rounded slopes with long uninterrupted surfaces available for overland flow.
