摘要
The bed load discharge of riverbed material with discontinuous wide size distribution is investigated in a flume experiment. The effect of flow intensity and bed material composition on bed load discharge is analyzed. Based on previous study on non-uniform sediment transportation, the relative flow intensity in consideration of the non-uniform bed material is put forward. The relation between the relative flow intensity and the function for calculating bed load discharge is investigated by means of regression analysis. Finally, a formula of the bed load discharge is established which takes into account of the effect of non-uniform discontinuous wide size distribution bed material on sediment transportation.
