Abstract : In this paper, a modified tachoida is applied to the estimation of sediment transport in a river. Eddy viscosity coefficient at the bottom which satisfied hydrodynamics stability of the flow is related to the sediment concentration. On this basis it was possible to determine the sediment stream in the river based on the bottom sediment composition.
