Kamafusa Reservoir that is located in Kawasaki-Cho of Miyagi Prefecture of Japan provides 36% of drinking water for Sendai City that is a million city of Tohoku district of Japan. However, it has a problem that the water in the reservoir occasionally has musty odor due to 2-Metil-isoborneol (2-MIB) produced by cyanobacteria such as Phormidium spp. If we can predict it through the analysis of these vertical profiles, we will prevent the appearance of the musty odor through improvement of operation for the forced circulation system and so on. Total mass of chlorophyll-a (net chlorophyll-a) in the whole of the reservoir, as an indicator of net biomass of phytoplankton, was calculated and compared with the water qualities during a phytoplankton bloom period. Segmentation spectrum analysis was also conducted to investigate the predominant periods of net chlorophyll-a before, during and after the bloom.

位于日本宫城县川崎町的釜房水库为东北地区百万人口城市仙台市提供了36%的饮用水。 然而，由于蓝细菌如席藻属（Phormidium spp.）产生的2-甲基-异冰片（2-MIB），水库中的水偶尔具有霉味的问题。 通过对这些垂直剖面的分析预测，可以通过改善强制循环系统的运行等来防止霉味的出现。计算了作为浮游植物净生物量指标的叶绿素a总量（净叶绿素a），并与浮游植物水华期间的水质进行了比较。 利用分段谱分析方法研究了水华前、水华中、水华后净叶绿素a的优势期。
