摘要
计算表明,潮泵效应在长江河口最大浑浊带悬沙输移中起着重要的作用。含沙量垂线分布的潮周期变化反映悬沙与床沙之间存在双向交换。据此讨论了最大浑浊带与拦门沙的关系。
Computation shows that the 'tidal pumping' effect has a significant role in the suspended sediment transport within the turbidity maximum of the Changjiang Estuary. The tidal change of vertical distribution of suspended sediment content in the South and North Channels confirms that there occurs bidirectional exchange between the suspended load in the turbidity maximum and the bedload on the river mouth bar. The relationship between the turbidity maximum and the river mouth bar is discussed.
