Webb24 maj 2024 · Ephemeral gullies (EGs) are small channels eroded and filled alternatively by concentrated overland flow and normal tillage at the same location ( Wu et al., 2024a ). On the Loess Plateau of China, EGs are estimated to contribute 35∼70% to the slope erosion mass ( He et al., 2004 ). Webb2 There are several types of soil erosion by water: sheet erosion, rill erosion, ephemeral gully erosion, classical gully erosion, and streambank erosion. The first type is sheet erosion. A physical process of sheet erosion occurs in the particle dislodgement due to the impacts of raindrops.
