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。

Abstract：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原
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.
