Abstract

Recently, there are many researches on sea level rise due to global warming. It is considered that problems on aquatic environment and disaster prevention will be caused by the sea level rise. Variations of high water level (H.W.L.) and low water level (L.W.L.) rather than that of mean sea level (M.S.L.) are important to discuss countermeasures against these problems. However, few researches on the long term variations of H.W.L. and L.W.L. have been carried out, and the characteristics of them are not made clear. In this study, in order to evaluate the variations of H.W.L., L.W.L. and M.S.L. the tide in Ariake Bay is discussed by analyzing tide data, numerical test and theoretical analysis. As a result, it is clarified that H.W.L., L.W.L. and M.S.L. have risen after 1960's, and the rate of rise increased in order of L.W.L., M.S.L., and H.W.L.. In addition, it is implied that M.S.L. rose corresponding to the decrease of tidal current due to the reclamation in Isahaya Bay.
