Abstract

Huge tsunami will be caused by the Nankai-Trough Earthquake, and will suspend marine sediment in Osaka Bay. Various materials contain in the marine sediment, and will be released to the water column by the tsunami. The spatial distributions of concentration of heavy metals, Cd, Pb, Cr, Hg and Zn, total nitrogen and phosphorus and suspended solid in the water column after the tsunami were estimated. The environmental standards of water quality may be exceeded in the inner part of Osaka Bay in the case of the worst conditions. And the suspend matters will drift during the tsunami.
