Abstract

In urban coastal areas in Japan, large-scale reclamation projects have recently increased, which have caused drastic changes in topographical features of the coastline. In Osaka Bay, the sea area of 5,200 ha have been reclaimed in the past 40 years and many development projects are under construction. As a natural consequence, the sea water has been polluted due to poor exchange of water with outer oceans and the load of nutritious substances discharged from rivers; hence, algal blooms occur independent of season and anoxia appears near the sea especially in summer. A 3-D baroclinic flow model is proposed to predict the tidally-interacting estuarine circulation and residual baroclinic currents in Osaka Bay and to evaluate the effects of hypothetical large-scale reclamation on the estuarine system.
