Recently, reduction of fish catch and poor harvest of cultured laver in the Ariake Sea have been serious social problems. Thus, many studies have been carried out in the Ariake Sea. On the cross-section connecting Ariake with Nagasu, nonuniform distribution of velocity exists. It is considered that this velocity distribution can bring about longitudinal dispersion and strengthen tidal exchange in the Ariake Sea. However, the mechanism for the phenomenon has not been clarified, yet. In this study, in order to clarify mechanisms of the velocity distribution, numerical simulations of tidal current were carried out. We examined in detail five test cases. As a result of this numerical study, it was clarified that the generation mechanism at ebb tide is different from one at flood tide, and the nonuniform distribution of velocity can cause tidal exchange of sea water.
