泥沙输移比
delivery ratio
- 泥沙输移比的变化，主要是由于流域内人为沉积汇的形成所致。
The dramatic change of sediment delivery ratio is caused by the formation of artificial sediment sinks, i. e. , sediment-trapping check-dams and reservoirs. - 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。
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. - 流域泥沙输移比与流域面积不存在固定的线性关系，其根本原因在于流域面积是度量衡单位，而不是影响因素。
The sediment delivery ratio is not correlative with the river basin area, because which is not a influence factor but a units of measurement.
