Abstract: Water quality simulation in bays is an important foundation for water environmental planning and evaluation, pollution control and treatment. A water quality model involving phytoplankton kinetics, nitrogen and phosphorus cycles, DO and CBOD, was developed based on the three-dimensional hydrodynamic model in a long-narrow bay, in China. The model can simulate not only the physical processes of the water quality variables, but also the chemical and biological processes. To resolve the difficulty in parameters selection and determination, a parameters optimisation method based on data driven theory was developed. Then, the parameters were selected and optimised based on the measured data. The simulated results matched well with the measured data and reproduced the spatial-temporal variation of the water quality variables in Xiangshan bay, which verified the effectiveness of the model parameters optimisation method
