摘要
近年来长江口一系列重大整治工程出现在横沙岛周围,工程将一定程度引起河床冲淤变化,通过横沙岛局部保滩工程项目前沿滩势近期演变特征研究,分析预测其未来的演变趋势,以及堤外滩涂地形变化的情况,对保滩工程的实施提供可靠的决策依据,确保一线海塘的安全。
In recent years,a series of major remediation projects in the Yangtze River estuary have appeared around Hengsha Island.The project will cause changes in riverbed erosion and siltation to some extent.Through the study of the recent evolution characteristics of the frontal potential of the Hengtan Island local beach preservation project,the future evolution trend will be analyzed and predicted.And the changes in the topogra-phy of the tidal flats provide a reliable basis for the implementation of the Baotan project to ensure the safety of the first-line seawall.
