In enclosed bay, water quality may change abruptly because high density outer seawater intrudes into the bay. To investigate the effect of seawater exchange on chlorophyll-a (chl.a) concentration in the bay, time series distribution of water quality were measured in Ohfunato bay in northern part in Japan. During the observation, abrupt change of chl.a concentration was observed although weather did not change clearly. Next, in order to investigate relationship between seawater exchange and chl.a variation, an ecological model was developed in the bay. Results of simulation showed that estimated chl.a concentration agreed with the observed value partially. From these results, it is concluded that seawater exchange is not always only improving but also impair the water quality in inner bay.
