The study results demonstrate that the construction of the causeway altered the lake's flow pattern and salinity distribution, with the possibility of a causeway with double opening paths as a solution to improve lake conditions. Vertical eddy viscosity was identified as a key parameter in forming density-stratified flow.
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. (C) 2021 Elsevier B.V.
