Abstract
In Osaka Bay, eutrophication phenomena occur in the bay head while nutrient concentrations are decreasing in the western part of the bay. In this study, we conduct numerical experiments in artificial control of inflow load to manage material circulation in the bay. The simulation results indicated that the future improvement of treated water quality would not contribute to resolution of organic pollution and might change nutrient balance in the eastern part of the bay. It would also be difficult to increase artificially the primary productivity in the western part of the bay due to the limitation of nutrient load potential from land and strong tidal mixing.
