How does slope affect soil erosion

WebSoil Erosion by Water. D.K. McCool, J.D. Williams, in Encyclopedia of Ecology, 2008. Soil erosion by water is the wearing away of the earth’s surface by the force of water and gravity, and consists of soil particle dislodgement, entrainment, transport, and deposition. This sequence of events occurs over a wide range of temporal and spatial ... WebThe main factors influencing soil erosion include the net rain excess, the water depth, the velocity, the shear stress of overland flows, and the erosion-resisting capacity of soil. The laws of these factors varying with the slope gradient were investigated by using the kinematic wave theory. Furthermore, the critical slope gradient of erosion was driven. The …
