沙质海岸在斜向波浪作用下将产生沿岸水流及沿岸输沙。因此,若在沿海岸修筑沿岸建筑物必然会破坏该地区的输沙动态平衡,发生明显的局部岸滩变形。本文应用Pelnard-Considere单线理论模式,通过物理模型试验等方法确定了有关计算参数,对毛里塔尼亚的努瓦克肖特港突堤上游的淤积岸线及淤积年限进行了计算,其结果可供港口建设等部门参考。
Sandy coast in the oblique wave will produce coastal water and coastal sediment transport. Therefore, if building coastal structures along the coast will inevitably destroy the dynamic balance of sediment transport in the area, obvious local beach deformation will occur. In this paper, the Pelnard-Considere single-line theoretical model was used to determine the relevant parameters through physical model tests and so on. The siltation coastline and siltation life in the upper reaches of Nouakchott Port in Mauritania were calculated. The results are available for port construction, etc. Departmental reference.
