Channel is the main sediment conduit and deposition area.From updip to downdip area, the sinuosity of channel increases and the flow energy decreases. 深水河道是物源的主要通道和沉积的重要场所，从上游至下游河道弯曲度增加，能量逐渐减弱。
The sinuosity or sinuosity ratio of a stream is expressed as the ratio of the length along the center line of the stream to the length along the valley. 一条河流的弯曲率或弯曲比，是以沿该河中心线与沿其河谷长度之比来表示的。
