If man-made islands are constructed in an inner bay, the tidal currents are changed and the rate of sea-water exchange is decreased, which often cause water pollution. In this study, model experiment and numerical analyses are carried out in order to investigate the effects of tidal currents and the rate of seawater exchange; furthermore, two methods for the improvement of seawater properties are proposed and examined by model experiments. Circulating flows around the man-made islands are observed in both the model experiments and numerical simulation.
