ABSTRACT
ABSTRACT: In order to clarify an impact of reclamation in Isahaya Bay on tidal current in Ariake Sea, Japan, we tried a comparison between tidal current before and after constructing the Isahaya sea-dike. Field observations of tidal current by three mooring electromagnetic current meters were carried out in 1993 and 2003 at same observation points. As a result of this research, it was clear that M2 constituent of tidal current decreased locally in the very important area for tidal exchange between the northern and southern parts of the Ariake Sea.
