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°
The study of sediment movement in the coastal shallow waters of our country is a practical discipline that has just been accelerated recently and is directly serving the production discipline. From the point of view of marine hydrology, the distribution of suspended matter in seawater and sediment transport along the sea floor and their movement along the tidal current are discussed. It is undoubtedly the direction of coast change, submarine scouring and silting, the direction of excavation channel and the waterway maintenance after the harbor was built A very important issue is, of course, a very complex one. In order to establish the port, we started from the autumn of 1983 to conduct a wide range of flow field surveys in this area. We collected samples of seawater under different weather conditions for analysis of suspended matter content. We observed the thickness of the floating mud and the seawater near the bottom According to a large number of observation data and calculations, we believe that the fifth pile area (ie the northern part of the New Yellow River estuary, from 38 °
