The dump, with the compact rock platform and high steep loose slope that is formed during coal mining, most serious area of soil erosion in a surface mine. Ground fissures are typical geological hazard mining areas. However, effect ground on remains unclear. Rainfall experiments were conducted to determine varying characteristics wetting front, runoff sediment production, denudation rate, as we...

A flume study was conducted using a soil, yard waste compost, and an erosion control compost to investigate the response to concentrated flow and determine if the shear stress model could be used to describe the response. Yard waste compost (YWC) and the bare Cecil soil (CS) control responded to concentrated laboratory runoff similarly in rill formation, and the shear stress model was useful in...

[1] In a recent paper by Polyakov and Nearing (2003) it was shown experimentally that the sediment transport capacity in a rill is not unique for a given soil type, slope, and flow rate. Indeed, they found that the transport capacity was dependent on whether sediment transport in the rill was occurring under net erosion or net deposition conditions. They concluded that this nonuniqueness in tra...
