摘　　要：The suspended sediment transport capacity is important for estimating the suspended load concentration and the ecological environment of the river.So far,few studies have been conducted to investigate the suspended sediment transport capacity in the vegetated sediment-laden flow.In this study,a new formula is derived to predict the sediment transport capacity in a vegetated flow by considering the absolute value of the energy loss between the sediment-laden flow and the clear water flow.Finally,the formula is expressed in a practical form by using the logarithmic matching method.
