Abstract

This study investigated the influence of a giant tsunami by the earthquake along the Nankai Trough on the benthic environment in terms of heavy-metal pollution in Osaka Bay as a pilot ocean. The high-resolution tsunami-tide and particle tracking simulations demonstrated that the marked resuspension area of zinc "hot spots" was locally formed in the nearshore ocean around landfills. After the tsunami, the zinc was transported by the tidal current and widely redeposited in the bay. The benthic environment and ecosystem can be improved only in areas around the "hot spots" where the zinc concentration decreases.
