Fujino Masataka, Kagemoto Hiroshi, Hamada Takaharu
Journal of the Society of Naval Architects of Japan   (180) 393-402   Dec 1996
While it is said that a floating structure has less significant effects on marine environment than a reclaimed island, it is important to predict precisely the effects of a floating structure on the surrounding environment, in particular, the surr...

西部造船会会報   (97) 95-104   Mar 1999   [Refereed]
In order to estimate the influence of very large floating structure on marine environment, it is necessary to know behavior of water surrounding the floating structure. In particular, it is important to evaluate water exchange under the floating s...

There has been much discussion about the cause of the decrease in M_2 tidal amplitude that has resulted from the reclamation of Isahaya Bay in Ariake Bay. As it has not been clarified yet, we tried to solve this problem using two approaches: (1) b...

A record breaking hypoxia occurred in the Ariake Sea in summer of 2006. The formation of the hypoxic water mass (DO<3mg L^<-1>) began in early July and continued to spread until the mid August, when the Typhoon 0610 passed over the bay. In early A...

沿岸海洋研究   47(2)    Feb 2010
有明海湾奥の循環流の実体を明らかにするために,海底設置型ADCPによる流速連続観測を行なった。得られたデータから残差流成分を抽出し,上層残差流の変動の原因を推定するため,潮汐,河川流量,風を独立変数とする重回帰分析を行なった。その検証を数値モデルにより行ない,さらに,湾奥全域の残差流場がどのように変動しているかを考察した。その結果,冬季における太良町沖の上居残差流は,長軸方向については潮汐の変動の影響を,短軸方向成分については風の変動の影響を,強く受けることが示された。また,小長井町沖の残...
