n.弯曲；曲折；弯曲处
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。
