Processes of Water Erosion

摘要: Summary. This paper considers some Australian research on the various processes of erosion and deposition involved in net loss soil water erosion. Detachment by rainfall is non-size-selective, presence highly size-selective process deposition, a sediment rich fine initially produced these processes. The nature changing character surface discussed. It suggested that development deposited layer coarser than original may be reason for commonly-observed general decline concentration toward constant value under steady rainfall. A distinction made between entrainment re-entrainment during event, though both are due to same shear stresses overland flow land surface. New ways mathematically representing developed, results compared with other previously-reported methods. Approximate equilibrium theory outlined simultaneous operation entrainment, approximate extended allow interpretation data measured ridge-furrow system, applied experiments Meyer Harmon (1985).
