| 摘 要： | 使用二维波浪潮流泥沙数学模型研究手段，通过工程实施前后的波浪场、二维潮流场、泥沙场、地形冲淤变化场的数值模拟和分析，对复杂的瓯江河口南口封堵工程的各种方案进行了研究，从对周围水沙环境影响角度论证了南口封堵工程方案的可行性。研究结果表明，将现潜堤加高的南口完全封堵方案是基本可行的，南口半堵方案是完全可行的。建议瓯江南口从半堵起步，逐步完成南口的完全封堵。

| Abstract: | By means of a 2D mathematical model of wave,tidal current and sediment,various schemes for stopping flow in South Branch of the complex Oujiang Estuary are studied through numerical simulations and analyses of wave filed,2D tidal current field,sediment filed and seabed deposition and erosion.The feasibility of schemes for stopping flow in South Branch of the Oujiang Estuary is demonstrated from the influencing point of view on environment.The study results show that it is basically feasible to completely st... |
