| Summary, etc. | A finite difference numerical model is developed to predict the hydrodynamic circulation in bays. Applying the multi-level approach, the water body is divided into three levels, in which the interfacial layers are fixed in space. The links between layers are the vertical mass exchange and momentum transfer in terms of interfacial shear stress. The thickness of upper and middle layers are decided according to the field measured data taken from Tokyo Bay on May 23, 1983 to represent an approximate thickness of a thermocline. The formulation of hydrodynamic model is based on the vertical integration of continuity and momentum equation for each layer. To study the dispersion of substances in bays, a multi-level approach is also used to formulate a three-level dispersion model. Mass transport and diffusive flux between layers are included in the model. The formulation of dispersion model is based on the vertical integration of convection-diffusion equation between the layer boundaries. An important connection between two models is that the computed layer velocities and water elevation from the hydrodynamic model serve as input data to the dispersion model. Consequently, the validity of the three-level hydrodynamic model is examined by comparing the computed flow condition with the field data measured at 9 sampling points in Tokyo Bay. The computed results seem in reasonable agreement with the measured data. Moreover, the important factors which affect the flow condition as well as the dispersion process - such as wind condition, interfacial shear stress coefficient, residual cunent, initial and boundary conditions - are discussed. The river discharge does not have much effect on the entire flow pattern except in the vicinity of the river mouth. Under the wind effect, flow direction is usually deflected in the upper layer and has a tendency to align with the wind direction. In the middle and lower layer, a return flow is driven to a direction opposite to the upper layer flow for compensation. |
