It is found that due to the existence of fine particles in flow, the transportconcentration of solid will increase with the same slope of gully.
研究表明，水石流中细颗粒的存在，其输沙浓度比相同纵坡下没有细颗粒时有很大提高。

Almost all the sediment yield models of heavy rainfall built in recent years have adopted the assumption of sediment transportconcentration of gullies and rivers being equal to 1.
近几年来建立的各类暴雨产沙模型，基本都采用沟道、河川泥沙的输移比等于1的假定。

The concentration front transport distance of and the maximum value of concentration increased with increased time in the process of water supply.
