Abstract
Tokyo bay is a typical enclosed bay which has a large population on the periphery, and accumulated sludge at the seabed consumes DO, which results in hypoxia in bottom layer during summer. Because of upwelling induced by wind, hypoxia comes up to sea water surface, which may kill fish and aquatic plants. Therefore, it is needed to understand the mechanism of the occurrence and transportation of hypoxia. Previous studies have shown that there is a problem in the reproducibility with forming stepped terrain by using the cartesian coordinate system. To solve such a problem, we applied Partial Cell into sinusoidal-shape topography in the three-dimensional numerical computation. Also, Partial Cell was applied into Tokyo Bay, which shows good agreement with field observation results in terms of vertical density profile.
