河床演变河床演变riverchannelprocess在河道水流与河床边界相互作用下，河床在垂直和水平方向上的变形。河床演变这个术语有两种理解：一是指河道从河源至河口、河谷各个部分的形成和发展；另一是指近代冲积河道的变化和发展。冲淤作用导致流程方向上河床高程的变化称纵向变形，与水流垂直的水平方向的变形，则称横向变形。这两种变形，在一般情况下，都是交织在一起的。按河床演变发展进程，分为在相当长时期内河床单一地朝某一方向发展的单向变形，如有些河流多年来河床一直不断淤积抬高；河床周期性往复发展的复归性变形，如浅滩在枯水期冲刷，在洪水期淤积，如此周期重复演变。此外，还有一些局部变形。河道输沙不平衡是河床演变的根本原因。当上游来沙量大于本河段的水流挟沙力时，水流没有能力把上游来沙全部带走，产生淤积，河床升高。当上游来沙量小于本河段的水流的挟沙力时，便产生冲刷，河床下降。在一定条件下，河床发生淤积时，淤积速度逐渐减少，直至淤积停止，河床发生冲刷时，冲刷速度逐渐减低，直至冲刷停止。这种现象称为河床和水流的自动调整作用。
