Soil detachment by shallow flow at low slopes
WebThat said, surface drains are essential and a useful tool to manage wet soils when used in the right location for the right reasons. Typical applications for using surface drains include: draining large quantities of surface water off land quickly; intercepting water flowing down from upper slopes to lower lying land WebThe effect of flow depth on soil detachment rate was also dependent on slope gradient. Stepwise variable selection analyses indicated that detachment rate could be predicted …

WebMay 13, 2024 · Based on the coupling of surface runoff and interstitial flow, we propose a modified failure mode for shallow soil slopes. In this mode, the safety factor of the shallow soil slope is derived, while the shear force acting on the slope from surface runoff is considered, as well as the resistance from the upper and lower edges of the sliding body. WebSoil erosion by rainfall and runoff is a natural and geologic phenomenon, and one of the most important components of the global geochemical cycle. Despite numerous studies on crop lands, there is still a need to quantify soil sheet erosion (an erosion form that uniformly removes fertile upper soil horizons) under grasslands and to assess the factors of the …
