Abstract: In Ohmura Bay, lots of environmental issues have been emerged. It is considered that the decrease of dissolved oxygen near the sea bottom will be caused due to the thermal stratification. In this study, a three- dimensional simulation model was developed focusing the water temperature and dissolved oxygen, and it was applied the periods of forming and deforming thermal stratification. From calculated results obtained under the period of forming stratification, vertical distribution of dissolved oxygen was influenced on the thermal stratification. On the other hands, in period of deforming the stratification, concentration of dissolved oxygen around sea bottom is becoming high as the stratification is weaker.
