Abstract
A numerical model to simulate the water quality around a Mega-Float in Tokyo Bay is presented The model consists of two parts, a hydrodynamic model and a marine ecosystem model. Tidal currents, water temperature, salinity and water density are calculated in a bay with/without a Mega-Float in the hydrodynamic model. A marine ecosystem model including the floating matters such as nutrients, phytoplankton, zooplankton and organic matters is extended to include not only the effects of marine mussels attaching on the bottom of the Mega-Float but also the benthic effects with the mussels fallen down to the sea bottom. The marine mussel is modeled as a macro benthos similar to an ecosystem model for a tidal flat estuary. Numerical results with/without a Mega-Float of 5 km length, 2 km breadth and 1 m draft in Tokyo Bay are given in graphics. Two evaluation functions are newly proposed to evaluate the changes of the water quality of the bay due to the installation of the Mega-Float.
