抄録
In Ohmura Bay, several kinds of environmental problems, such as eutrophication, depletion of dissolved oxygen at sea bottom, and so on, are occurred recently. It is necessary to make clear the mechanism on water quality changes from the interdisciplinary viewpoints for recovering the water environment of this bay. In this study, a water quality simulation model is developed focusing on the consumption of dissolved oxygen by organic materials in sediments (Sediment Oxygen Demand :SOD). To ensure applicability of this model to Ohmura Bay, tidal current simulation is firstly carried out. Next, water quality changes, especially dissolved oxygen, are simulated. This developed model predicts the spatial distribution of tidal current and dissolved oxygen to some degree. On the other hand, it is necessary to model the water quality changes due to the chemical and biological reactions under thermal stratification for adequate simulation, in future.
