Abstract: Three-dimensional baroclinic hydrodynamic model BACHOM-3 is developed using ADI (Alternating Direction Implicit) finite difference scheme. The model is applied to a uni-nodal standing wave in a rectangular basin. The model results for the surface elevation and velocities coincide with the analytical results. To verify the field applicability of the model, the model is applied to the Suyoung Bay in Pusan, Korea. The numerically predicted velocity fields during spring tide are compared with field measurements, the comparisons show good agreements. Computed velocity fields show that the phase difference of velocities between the surface layer and the bottom layer occurs and the phase of velocities laggs more and more with height from the bottom. Then, the model is applied sucessfully for the computation of wind-driven flow fields. Convergence time of the model required to obtain the numerical stable solutions of the tides and tidal currents is very short as about 1 tidal period, and the stability of the numerical solutions is very high.
