基于水文气象、水深地形、表层沉积物等实测资料,运用水动力和泥沙输运数学模型,分析了海阳港周边海域泥沙运移趋势,预测了海阳港东港区建设后的岸线演变趋势,探讨了工程建设对周边海域冲淤环境的影响.研究结果表明,研究区泥沙运移趋势总体为自西向东;工程建设导致西港区东侧的淤积作用和南侧侵蚀作用减弱,而东港区码头南端和北侧近岸的侵蚀作用和淤积作用增强;东港区后侧岸线以淤进为主,5年后岸线趋于动态平衡状态.“,”We discussed in this paper the transportation of sediment in the water around the Haiyang Harbor,and predicted the evolution of the sandy coast after the construction of the East Wing of the Haiyang Harbor,using the hydrodynamic and sediment transportation numerical model and based on various data including hydrology,meteorology,water depth,and surface sediments.The impacts of the construction of the East Wing of the Haiyang Harbor on the erosion and deposition system of the surrounding waters were unraveled.The results revealed that sediments in the study area are generally moving in a trend from west to east.The erosion and deposition in the waters between the east and west wings will be weakened after the construction of east wing,but enhanced in the south and north.The sandy coast will suffer from siltation after the construction and reach a dynamic balance within a time span of 5 years.
