Abstract: Physical model is an effective approach in studying sediment problems such as the degradation and aggradation in a reservoir. For reservoir sediment problems, the deposited material is usually fine and the coherence force plays an important role in the evolution process. Therefore, it is usual in physical model designing to consider some special properties of fine sediment transport and the corresponding riverbed evolutions, especially for the sediment erosion processes. A dry weight scale was introduced into present model designing for the erosion problem research of fine sediment particle, in which the coherence force is the main resistance to erosive processes. The necessary steps for such a physical model research and, some fundamental principles for the designing of a reservoir erosion model are discussed. A case of Liujiaxia Reservoir, which is located at the upper reach of the Yellow River, is employed to verify present approach of model designing. A wonderful recurrence in the verification tests and satisfactory agreement with the data site-observed illustrated that the method introduced here is a reasonable one.
