Abstract
Tidal artificial lake capable of inflow and outflow of seawater is planned for waterfront and eco-friendly space at Songdo, Incheon, Korea. This study for hydrodynamic behaviors of tidal artificial lake was carried out and predicted about water level and velocity within the lake corresponding to width of channel or waterway using by 1 dimensional numerical model(CEA) and 2 dimensional numerical model(FLOW2DH). As a result, the proper width, 100.0m of the channel between the lake and the open sea was calculated reasonable conclusions such as tidal phase lag and maximum velocity from CEA. Also, water level and velocity of each point within the lake was predicted and compared to the measured data from FLOW2DH. FLOW2DH was added to the gate control case for maintenance and administration purpose of the lake and obtained the results that the velocity was decreased by approximately 20% at flood and 50% at ebb than the case without gate control.
