输沙率输沙率sediment transport concentrationShushal位输沙率(sediment transport eoneentra-tion)单位时间内由河道水流输移通过某断面的泥沙量。河流的总输沙率包括推移质和悬移质两部分。推移质输沙率与水深和流速的关系密切，故输沙率沿河宽的变化较大，所以许多推移质输沙率算式是指单位宽度内在单位时段中的输沙量。而悬移质输沙率沿河宽的变化相对较小，常以悬移质挟沙力表示.再与流量联系起来，即可求得单位时间内的悬移质输沙量。输沙率随水流泥沙条件而变化。在河床有单纯的冲刷或淤积情况时，河道各断面的输沙率是不同的。在河段处于冲淤平衡时，输沙率的计算见水流挟沙力。 (周耀庭)
