| 摘 要： | 根据甬江和口外金塘水道2010年7月实测水文泥沙资料,对水动力、泥沙特性和悬沙输移进行了分析。结果表明,在甬江口及其附近水域潮差较小,潮流强,呈往复流;甬江河道自上游向下游含沙量逐渐增大,金塘水道北部水域含沙量大于南部水域,泥沙主要来自北部的长江口及杭州湾。

| Abstract: | Based on surveyed hydrological sediment data of Yongjiang and Jintang channel in July 2010, the analysis on the hydrodynamic, sediment characteristics and suspended sediment transport is carried out. The results show that tidal range in Yongjiang River estuary and its adjacent water areas is relatively small, while tidal current is strong and reciprocating. Sediment concentration increases gradually from upstream to downstream in Yongjiang river, and the sediment concentration in the northern part is larger than that in the southern part in the Jintang channel. The sediment mainly comes from northern Yangtze estuary and Hangzhou bay. |
