| Research Abstract |
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.
