| 摘 要： | 采用ADCP实测水流资料与悬沙含量实测资料相结合的方法,对长江口悬沙运动进行分析。结果表明,泥沙再悬浮由潮流驱动,造成悬沙含量变化滞后于流速的变化,悬沙含量的峰值滞后于流速峰值。悬沙运动模式与水流基本一致,也存在三种不同形式的悬沙环流输移模式,并分析了潮流量与输沙率之间的关系。

| Abstract: | According to ADCP data and suspended sediment concentration,suspended sediment movement in the Yangtze River Estuary is studied.The result shows that sediment re-suspended is arisen by tide,the change of suspended sediment concentration lags the change of flow velocity,and the peak value of suspended sediment concentration lags the peak value of flow velocity.Suspended sediment has three transport modes,and the relationship between tidal discharge and sediment discharge is also studied. |
