摘要
连云港埒子口—灌河口海域为淤泥质向粉沙质海岸的过渡带,水沙运动复杂。在考虑淤泥质和粉沙质泥沙特性的基础上,构建泥沙数学模型,可以在一个模型内同时模拟两种不同性质泥沙运动,验证结果令人满意;同时,利用所建立的泥沙数学模型还可以计算悬沙的沉速场,据此分析埒子口—灌河口过渡带的泥沙运动特征和影响因素。
The sea area from Liezikou to Guanhekou in Lianyungang is located in a transitional zone from muddy coast to silty sandy coast, in which the flow and sediment movement are very complex. Considering the characteristics of mud and silty sand, a 2D flow and sediment mathematic model is established. The verification showed that the model can satisfactorily sim- ulate different kinds of sediment movement at the same time; meanwhile, the model can be used to compute the sink speed field of suspended sediment, and to analyze the feature of sediment transport and the influence factors in the sea area.
