Loess flow
Witryna8 kwi 2024 · High-intensity rainfall, over-irrigation of agricultural fields, and freeze–thaw cycles induce gradual groundwater infiltration within the upper loess layer, and this water flow generally overflows from slopes (Zhou et al. 2014). The same mechanism leads to pothole erosion and increases the chances of hillslope failure of the walls of gullies ... Witryna31 maj 1999 · Hyperconcentrated flows are an important factor responsible for the high-intensity erosion and sediment yield in the middle Yellow River basin. Many previous studies have indicated that the sediment delivery ratio on the Loess Plateau approaches 1. This can be explained by the action of hyperconcentrated flows.
