| Abstract: | The hydrodynamics and water quality in Hakata Bay,Japan are strongly affected by the seasonal variations in both the gravitational circulation and the stratification in the bay.The three dimensional hydrodynamics and water quality model has been developed to simulate the long-term transport and fate of polutants in the system.The model is so unique that it completely integrates the refined model of the hydrodynamics,biochemical reactions and the ecosystem in the coastal areas.It predicts daily fluctuations in the oxygen content at different depths in water throughout the year.The model has been calibrated well against the data set of historical water quality observations in Hakata Bay. |
