Abstract

There are a lot of tidal flats in the Ariake Sea and the Yatsushiro Sea. The area has been reduced by large reclamation since the beginning of twentieth century. Changes in the coastline could have made the eigen-oscillation period of the bays short, which might decrease amplification of tidal amplitude in an inner bay. We tried to clarify the effect using two approaches:(1) harmonic analysis of observational water level data at Misumi and (2) numerical experiments using a three-dimensional Princeton Ocean Model (POM). As a results of this study, it was clarified data decrease of outer sea tidal amplitude was the most influential factor in long-term changes of the M2 tidal amplitude and the M2 tidal amplitude in 2000s was the smallest value over the past 80 years.
