Based on the development of a generalized model, some simplified methods for calculation of sedimentation in small reservoirs are deduced according to the reservoir storage curves, including the average sedimentation elevation method, the correction factor method, the cone formula and prismoidal formula for regularly generalized sedimentary bodies, and the partial surface area method. These methods are simple in calculation, and greatly improve the working efficiency.
