黄海西部沿岸流（简称黄海沿岸流）是黄海环流体系的一个重要组成部分，是末次冰消期海平面快速上升后逐步形成的，受季风、黑潮入侵、温盐斜压作用及河流径流的影响，它存在着季节变化，其作用下的泥沙输运等也存在一些科学问题。本课题通过构建三维沉积动力数值模型，以实测海洋水文、水动力数据验证，从沿岸流发育的动力机制出发，设置敏感性数值试验，揭示不同季节黄海沿岸流发育的主要控制动力因素；研究沿岸流的季节变化规律和泥沙输运特征；结合浅地层剖面解译出的高水位期以来沉积地层空间分布特征，进一步探讨黄海沿岸流对北黄海泥、环山东半岛斜坡沉积体和南黄海中部泥的沉积动力机制。

The Yellow sea western coastal current (in short as the Yellow Sea coastal current) is an important part of the circulation system of the Yellow Sea. It gradually formed at the sea level rapid rise after the last deglaciation. It exists seasonal variation by the monsoon, the Kuroshio intrusion, influence of the thermohaline baroclinic and river runoff and the coastal current has also effect on the sediment transport. In this topic, on the basis of a fully validated three-dimensional dynamic numerical model, we set the sensitive numerical experiments to study the seasonal variation of the coastal current and reveal the main dynamic factors controlling the Yellow Sea coastal development in different seasons. Further, the seasonal variation of sediment transport by the coast current will be studied, then we will explore the sedimentary dynamic mechanism of the Yellow Sea Coastal current on the North Yellow Sea muddy area, clinoform off the Shandong Peninsulaand the South Yellow Sea Muddy area combinate the spatial distribution of sedimentary strata after high-water level.
