现代黄河三角洲是一块新的陆地,由于陆地的形成时间短,未经长期的地质作用,形成的陆地和岸滩结构松散,岸滩泥沙的动态性强,整个岸滩处于极不稳定状态,地球陆地表面最活跃的地区之一。本文以黄河三角洲地区的东营港岸滩为研究对象,着重研究港口的建设对岸滩附近的海水动力的影响,进而探讨海洋动力的变化对岸滩地貌变化的影响,综合分析在工程建设影响下,波浪,潮流,风暴潮等水动力的变化,海洋水动力变化对岸滩地貌的影响。
The modern Yellow River Delta is a new land. Due to the short formation time of the land and the long-term geological effects, the formation of land and shore beaches is loose, and the dynamics of beach sediment is strong. The entire beach is in a very unstable state. One of the most active areas on Earth’s land surface. In this paper, the Dongying Harbor Bank in the Yellow River Delta is taken as the research object, and the impact of the port construction on the hydrodynamic force near the beach is studied. Then the impact of the marine dynamic changes on the landform changes is analyzed. Under the influence of the project construction, , Tidal current, storm surge and other hydrodynamic changes, the impact of ocean hydrodynamic changes on the beach landscape.
