Abstract: Water pollution is a social problem in an enclosed bay with a large city, such as Osaka Bay. However, there are a lot of uncertain points in the pollution mechanism. To clarify the mechanism of water environmental degradation by reclamation, numerical analysis have conducted using a 3-D flow and water-quality model. The results indicated that coastal landform change could influence the currents and water quality not only around the reclaimed land but also in the entire bay and the adjacent seas by weakening the anticyclonic circulation flow in the bay head.
