This study analyzed Changes in water level, velocity and water exchange rate of Cheongna Central Lake using MIKE 21 Flexible Mesh (FM) model. The Artificial Lake that changes according to the operation conditions such as the use of flow generator, drainage location and discharge supply condition. The results revealed that the rate of a lake’s water cycle rose when the flow generator operated, causing the water to run at higher velocity in the stagnation regions. Especially, operating the drainage halls located in both ends of the lake showed better water cycle efficiency than using a drainage hall in the center of the lake. This study suggests management plans to solve dead water regions and enhance the water cycle in the artificial lake. The test result from numerical model in this study will hopefully serve as fundamental data used on designing similar facilities going forward.
