摘要：
Based on the field data, this paper analyses the relationship between the effect of sediment transporting floods, the flow, the sediment concentration and their combination in flood period, and develops an estimation formula for sediment release ratio of floods by regression approach. Twenty floods have been picked out as high efficient sediment transport flood after being comprehensively analyzed water volume for sediment transport and sediment - releasing ratio. In view of the mean case of high efficient sediment transport floods, it is recommended to utilize the Xiaolangdi Reservoir that is capable to regulate floods with mean flow of about 3, 200 m(3)/s and mean sediment concentration of about 65 kg/m(3) to decrease channel sedimentation on the lower Yellow River and save the scarce water resources.
