摘要:
根据东大港水道所设站位连续2个潮周期的水文、泥沙测量资料,对水体含沙的悬浮与沉降潮流动力过程进行了论述,水体各层含沙量与潮流大小之间存在着动力响应关系。对水道含沙量垂线分布关系进行了分析和构建,给出了对数关系式,明确了西洋水道主槽水体含沙量垂线分布特征。

Dynamical process and vertical distribution of suspended sediments in Dongdagang tide channel
Abstract:
On the basis of analyzing the two tidal periods′successive survey results on the tidal current and suspended sediments at No.4 station in the tidal channel called Dongdagang, the characters of tidal current and the rule of suspended sediment change are further studied. The surveyed suspended sediment concentration data were fitted to the relative depth. The vertical distribution characters of suspended sediments were discovered.
Key words:  Dongdagang channel  tidal current  suspended sediment concentration  vertical distribution  fitting
