The present investigation aims to explore the hydrodynamic and salinity distribution of the lake, following the construction of the causeway by using MIKE 3 Flow Model FM.¹ The results indicate that the construction of the causeway changed the flow pattern and salinity compared to the condition prior to its construction. The salt–water balance between the two sides of the lake was not observed with the existing opening. Adding a new breach on the causeway (two breaches) revealed that, on average, the exchange flow from south to north and north to south has increased to 185 and 176 percent, respectively. The amount of the exchange of salt from south to north and north to south has also incremented to 181 and 174 percent, respectively, compared to the existing condition (one breach). The causeway with double opening paths is offered as a solution to improve the lake conditions. Moreover, results revealed that the vertical eddy viscosity is a key parameter in forming the density-stratified flow, salinity distribution, and flow circulation.

本研究的目的是在利用MIKE 3 Flow Model FM修建堤道之后，探索湖泊的水动力和盐分分布。^1个结果表明，堤道的施工与修建前的状况相比，改变了流态和盐度。现有开口处未观察到湖两岸的咸水平衡。在堤道上增加一条新的缺口（两次缺口）显示，平均而言，从南到北和从北到南的交换流量分别增加到了185％和176％。与现有条件（一次突破）相比，从南到北和从北到南的盐交换量也分别增加到181％和174％。提供具有双开放路径的堤道作为改善湖泊状况的解决方案。此外，结果表明，垂直涡流粘度是形成密度分层流，盐度分布，
