OCEAN ENVIRONMENT CHANGES DUE TO AN OFFSHORE AIRPORT IN ARIAKE BAY

An assessment of the ocean environment is presented for the planning of an airport in Ariake Bay in Japan which is known to have large tides and a vast tidal marsh. A newly developed ADI method is applied for calculating the tides and currents in the bay with the effects of the tidal marsh. Moving boundaries on the tidal marsh are treated by the quasi-statical approximation at every time step in the calculations. Assessment functions for the changes of tides and currents are defined by the ocean area which is affected by the construction of an airport in the bay. Three locations of an island airport and an approximated floating airport are compared in the assessment functions. Diffusion of COD from four rivers is also simulated and the distribution patterns of COD density after 30 tides are compared.
