%X Overland flow is the main cause for slope erosion,which has unique hydrodynamic characteristics.This paper made a systematic and thorough discussion on the flow pattern,frictional resistance,mean flow velocity measurement and runoff energy of sediment-laden overland flow,sediment concentration as well as the impacts of the above.Reynolds number(Re) and Froude number(Fr) are used to express flow pattern.The branch point of Re exists in the definition of "laminar flow",and raindrop splash is the main reason f...
