The result shows that the stream power, mean velocity and grain shear stress are effective in predicting sediment transport rate and the unit stream power, Froude number and Velikanov parameter are better indexes for predicting sediment concentration.

• 结果表明 ,水流功率、平均流速、沙粒切应力能较好地预测输沙率而单位水流功率、佛汝德数、Velikanov参数则较好地预测输沙浓度。
