SIMULATION OF WATER EXCHANGE IN BOHAI BAY
Water exchange is an important hydrodynamic character of sea bays, and it is the basis for the study of the environmental capacity of sea bays. An integrated hydrodynamic-dispersion numerical model is set up to study the water exchange in Bohai Bay, China with the concept of average residence time. The model is verified against field measured data, with the model-predicted water elevations and velocities generally agreeing well with the field measurements. The numerical model results show that the average residence time for the whole Bohai Bay is about 580 days (considering only M2 tide), and it is affected very slightly by the initial release time of the tracer. The average residence times for different sub-areas in the sea bay are evaluated and it is found that the average residence times of the sub-areas in the west part of Bohai Bay are longer than the average time of the whole Bohai Bay. In addition, numerical results show that the predicted average residence time of every sub-area is affected slightly by the release time of the tracer except one sub-area adjacent to the east boundary of Bohai Bay.
