This paper reviews the previous studies on the relationship between sediment delivery ratio and drainage area which reflects essentially the relationship between sediment yield and drainage area.
提出至今所有流域泥沙输移比与流域面积关系其实质都是流域输沙模数与流域面积的关系。
The dramatic change of sediment delivery ratio is caused by the formation of artificial sediment sinks, i. e. , sediment-trapping check-dams and reservoirs.
