石浦港下湾门水道的水沙运移特征

Hydrological and sediment features and transportation in Xiawanmen Channel,the Shipu Harbor

根据2003年9月5～10日的实测水文泥沙测验资料，对石浦港的主航道——下湾门水道各测站的潮流和悬沙特征进行分析研究。结果表明，研究海域潮流流况主要受地形影响，悬沙运移涨潮大于落潮，泥沙进入石浦港内。对下湾门水道的水沙运移特征进行分析，有助于了解石浦港内水沙运移和冲淤状况。

Tidal current and suspended sediment features of Xiawanmen Channel which is the main sea-route of the Shipu Harbor can be used to make quantitative analysis and forecast of the erosion accretions latter on. Based on the surveying data at 3 stations in September, 2003, the features of tidal current, suspended sediment concentration distributions and transport were analyzed. The results showed that the tidal current is affected by the topographic condition and the net suspended sediment flux is entering the Shipu Harbor, consistent with the direction of residual current.
