Abstract

 Ocean currents and densities in Miyako Bay under various meteorological conditions were reproduced using an ocean current model, CCM, to examine characteristics of the current and density structures. Calculations using topographic data obtained before and after the tsunami were also conducted to evaluate the influence of topographic changes on the current and density structures. Results show that the inflow rates from two rivers strongly influenced the sea surface density distributions. Moreover, results show that topographic changes caused by the tsunami locally influenced the sea surface density and the direction of the currents.
