ABSTRACT
The research of sediment movement on bed surface is one of the most important coastal problems around the world. In this paper, the vertical distribution formula of sediment concentration is improved by summarizing theoretical formulas of predecessors. A developed formula of total sediment carrying capacity is obtained by dimensional analysis. The formulae of sediment carrying capacity of suspended load and the bed surface deformation equation are derived by using micro element analysis method. The equation for calculating and simulating the erosion and deposition of the bed surface under the condition of stable bed surface is simplified. The flow around a cylinder is calculated and the distribution of erosion and siltation field is plotted.
