| 英文摘要 | Soil erosion by overland flowon hillslopes is one of the most crucial fundamental sediment yield processes. Generally, Saint-Venant equation based overland flow model is widely used to model this special flow, and in turn, the sheet erosion. However, it becomes more and more clear that the overland flow, which generally involves irregular micro landform, could behave different characteristics from river flow in which classical depth-averaged model suits well. The key issue is that the characteristic length of the irregular micro landform is considerable large comparing with the overland flow depth, which leads to nonuniform velocity profile in the depth direction. Thus, this paper employed full Navier-Stokes equation to study the overland flow on partially inundated irregular micro-relief and discuss the self-enhanced sheet erosion processes. © 2017 Taylor & Francis Group, London. |
