A numerical simulation of water flow and water quality for the environmental impact assessment of a very large floating structure or a Mega-Float in coastal sea is described. A model consists of two parts, a hydrodynamic model and a marine ecosystem model. Some approximate solution methods for a Mega-Float type floating pontoon are introduced. Tidal currents, water temperature, salinity and water density are calculated in a hydrodynamic model and some low-level floating matters including nutrients, phytoplankton, zooplankton and organic matters are calculated in an ecosystem model. Simulation results with/without a Mega-Float of 4.75 km length, 1.5 km breadth and 1.2 m draft in Tokyo Bay are given by graphics. Changes of marine environmental factors due to the installation of the Mega-Float with the breakwater are also included.
