August undefined, 2024

WebShallow landslides can often happen in areas that have slopes with high permeable soils on top of low permeable soils. The low permeable soil traps the water in the shallower soil generating high water pressures. As the … WebSoil detachment is known as an important process in soil erosion and its quantification is necessary to establish a basic understanding of erosion. This study was carried out to find the best flow erosivity indicator(s) for predicting detachment rate at low slopes. For this purpose, 12 experiments including 6 flow discharges (75, 100, 125, 150, 175 and 200 …

Surface and shallow subsurface water flows on the tundra are known as water tracks (Mcnamara et al., 1999; Trochim et al., 2016), which are present at our site in the form of … WebVegetation growth is inhibited where high wind stress and low moisture availability prevail, such as at windward and south-facing slopes (Hugenholtz and Wolfe 2005b). The process of dune stabilization tends not to be a linear function of time, with stabilization slowing and following a negative exponential function in later stages (Hugenholtz and Wolfe 2005b). in a better place quote
