辽东湾北部浅海区现代冲淤动态分析

通过对辽东湾北部浅海区现代动力分析，本文对该区岸线变化、潮滩冲淤以及水下动态进行了初步分析。用细粒级沉积物堆积的沉积延迟效应理论论来解释该区西部岸线向海推移和潮滩淤积。水下部分－１—－３ｍ处为波浪破碎区和潮流强烈作用区，受到侵蚀和冲刷，并且悬浮的泥沙几岸和深水区运移，形成两个稳定堆积区。

MODERN EROSION AND ACCUMULATION TRENDS OF THE NORTH SHALLOW REGION OF LIAODONG BAY

Through the analysis of the modern dynamics of the north shallow region of Liaodong Bay, this paper presents preliminary studies on the change of coastline, the erosion and accumulation of the sediments in the int&rtidal zone and the area under water. The accumlation of fine grade sediment on the intertidal zone is explained with the setting lag effect theory. In the area with depth ranging from-1m to-3m, where the sediments are eroded by breaking waves and tidal currents, the suspended substances are transported shoreward and to the deep ses area, and two stable accumulation regions are formed.
