【Abstract】 In fact, the calculation of sediment transport intensity is to set up a relationship between sediment transprot rate and flow intensity parameter. But the measures of flow intensity what is used in the existing sediment transport formulas are quite different. Various measures of flow intensity have been synthesized and concluded, and a generalized form of measure of flow intensity has been put up. Based on this genralized flow intensity, a unified sediment transport equation is proposed. This unified equation can summarize most of the current sediment transport equations.更多还原
