Ocean Circulation Response to Inflow from Abukuma River Outlet

Abstract

The focus of this study is to promote relevant modeling survey on Land-Ocean coupling modeling approach applicable for the bay and estuary zone affected by river inflow and associated pollution from the Abukuma river basin in Japan. The modeling approach has been studied by combining hydrological model and ocean circulation model (MSSG model, JAMSTEC) which runs within supercomputer (ES2), and associated data manipulation techniques for boundary conditions of hydrological and oceanographic modeling. There were simulated 3 different cases, at first circulation of ocean itself induced by its own temperature and salinity data differences, at second response of the ocean circulation to inflow from the river outlet, and finally response of the ocean to river inflow with included rotation of the Earth as Coriolis effect.
