A feasibility research project on large scale floating structures for the ocean space ulitization is undergoing now in Japan. Floating structures are superior to the reclaimed island in some points such as less impact on ocean environment. But, because the scale is huge compared with existing ones, environmental assessment of such a structure in a bay is necessary before construction. In this paper, we present a method to simulate tidal flows of a bay with a very large floating structure using muli-level model. Pressure under the pontoon is obtained by solving the Poisson equation. Effects of vertical displacement of the pontoon due to tidal force are considered in the tidal simulation. Tidal currents, residual currents and wind driven currents in a bay with/without a structure are presented graphically and discussed.
