摘要
通过建立江苏沿海大范围及小范围的平面二维水沙数学模型,将此水沙模型应用于腰沙、冷家沙围垦工程研究,通过流速流向、年冲淤变化指标,分析工程对周边海域水沙环境影响以及工程区域的年回淤强度。结果表明:围垦工程产生的影响范围有限,围垦工程南北两侧水域,流速减小,地形成淤积的态势;工程东段水流流速增大,产生一定的冲刷,对建立深水码头有利。
In this paper,two-dimensional flow and sediment mathematical models were set up to study the changes of the Yaosha-Lengjiasha reclamation project in Jiangsu Province. According to the changes of current and annual erosion and deposition,the impact on the surrounding sea and the annual change in erosion and deposition after the project was analyzed. The results show that the influence of the reclamation is limited in certain areas. The tidal velocity in the north and south area of the project decreases,while the velocity in the west area increases, and it is favorable to build a deep water wharf.
