汕头港广澳港区防波堤工程波浪输沙及对濠江河口影响研究

依据外海1 a期波浪观测资料,采用沿岸输沙公式及波浪数学模型方法对海湾内波浪沿岸输沙及岸线变形情况进行研究。计算结果表明,防波堤工程实施后,改变了濠江河口附近原有波浪动力条件和净输沙方向,西侧岬湾两头将发生淤积,岬湾中部发生侵蚀,约5 a后,岸线将会与河口西侧的两个小岛相连,形成连岛沙堤。

Longshore sediment transport due to Guang'ao breakwater project of Shantou port and its effect on Haojiang estuary

Based on one-year wave observations off the coast, this paper studies the longshore transport rate of sediment and coastline deformation of the gulf by a joint method of formula and wave mathematical model.Calculation results show that the wave dynamic condition and sediment transport direction are changed nearby Haojiang estuary after implement of the project, and as a result, siltation occurs at two ends of the bay to the west of the estuary and erosion in the middle of that; About 5 years later, a sand barrier will form between the coastline and the two islands on the west side.
