【摘要】 <正> 在我国近岸浅水域泥沙运动研究是最近才加速兴起的一门实用的、直接服务于生产的学科。从海洋水文角度来探讨海水中悬移质与海底推移质泥沙分布以及它们随浪潮流运动的规律,对于海岸变迁,海底冲淤,开挖航道的方向.以及建港之后航道的维护无疑是一个非常重要的问题,当然也是十分复杂的问题。 为了建港工作需要,我们从1983年秋开始,对这个海区进行广泛的流场调查;采集不同天气条件下各层海水水样,进行悬移质含量分析;潜水观察浮泥的厚度和近底层海水混浊情况,根据大量的观测资料和计算,我们认为五号桩海区(即新黄河口北部,从38°更多还原

【Abstract】 It’s vety important to study the transportation of suspended matter for the coats engineering. We have to understand the quantity and direction of the movement of suspended matter for studying the change of coast and deposit of sediment on the sea bed.For this porpose we have measured the currents and the quantity of suspended matter near the section B in different seasons since 1983. According to data and calculation, we’ve got the following conclusions:1)The quantity of suspended matter transported by tidal current through the section B is about 19.6 million tons each year, but the transportation quantity is the same in both direction of flood tide and ebb tide.2)The quantity of suspended matter removed by residual current is about 8.57 million tons each year, the direction of transpotation points to north-west.3)The transportation quantity of suspended matter due to the wind-driven current in storm weather is about 0.95 million tons each year,the direction of transportation points to south.更多还原
