A lot of investigations and the research on the generation mechanism of oxygen-deficient water are being executed by the government and laboratories. However, a complex system by the interaction of a physical process, the metrological element, and the living thing is formed in the littoral region. It is a current state that the generation mechanism of oxygen-deficient water is not clearly shown. In the present study, it paid attention to changes with the lapse of time such as oxygen-deficient water, the weathers, and hydrographic phenomenon generated in Ariake Sea. And, variability characteristics of oxygen-deficient water and the relativity of the metrological element were examined by using the discrete wavelet transform. As a result, it is expected for the generation cycle of oxygen-deficient water and the influence period of the metrological element to become clear, and to become the index of the site investigation and the evaluation approach., http://www.jsce.or.jp/}, pages = {78--84}, title = {離散ウェーブレット変換を用いた有明海湾奥部の貧酸素水塊の変動特性と気象要素}, volume = {2010}, year = {2010}, yomi = {タキカワ, キヨシ and ソノダ, ヨシヒロ and マスダ, タツヤ and イガラシ, マナブ} }
