Study on the Formula of Equilibrium of Near-bed-concentration of Suspended Sediment

Based on previous research/study, with definite physical concepts and the point of view that there is the same amount of sediment exchange between bed load within suspended load and riverbed sediment, a formula of concentration of sediment near the bottom of a river was derived in this paper. Then, the formula of near-bed-concentration of suspended sediment was derived by the author through basic differential equations of vertical distribution of suspended load. It could be validated by measured datum that the formula can properly fit the equilibrium of near-bed-concentration of suspended sediment in fluvial river.
