Yongam lake is a standard freshening reservoir introducing desalt fresh water from adjacent Yongsan estuary lake, which is located in the southwestern coast of Korea peninsula. This paper carried out the two dimensional simulation of flow field by adopting finite difference method on general curvilinear coordinate system to analyze the inflow and mixing pattern in the Yongam lake. In addition, the changes of salinity and the spring layer of fresh-salt water were computed by a numerical method using salinity equivalent equations with field observations. As the results of the numerical simulations of flow fields, the computed time-varying horizontal velocity vectors were two dimensionally visualized, which can successfully be used to investigate for the flows of final enclosed freshening reservoir. In the desalinization process, the salinity was predicted 1,200•`1, 400 mg/l and 1,000•`1, 700 mg/l for the observed and the computed values separately. The spring layer of fresh-salt water related to hydraulic stability was found 14•`20 meters below the water surface near the middle of sea dike, while computer simulations were computed 16•`21.5 meters and 17.5•`19.5 meters below the water surface for with and without desalt fresh water inflow, respectively. From this simulations, it is cleared that the salinity of Yongam lake was influenced the intrusion of salt water from dike, the vertical diffusion and mixing through a spring layer, wind, tidal phenomena and was greatly related to the inflow discharge of desalt fresh water.
