영문 초록

This paper describes the characteristics of tidal currents in the Mokpo Coastal Waters by using the two-dimensional nonlinear hydrodynamic equation. The basic equations are derived by Navier-Stokes momentum equation and continuity equation and its characteristics critically are reviewed, and they are analysed by the implicit finite defference method. The numerical model is constructed two-dimensional(depth-averaged) simple layer model. This paper investigates the stability of solution and convergence of solution in application of the method to Mokpo Coastal Waters, and the reproducibility of the simulation is also discussed in comparison with the results of field survey. The following items are clarified through the numerical investigation; ⅰ) The reproducibility of tidal range and currents are quite acceptable, comparing with the results of model tests and field data, and ⅱ) Tidal cycle for convergent solution is six tidal cycle. also, ⅲ) If not provided a special condition on the tidal flow, the frictional coefficient for the flow on the bottom of the bay can be represented by Chezy’s equation which considers the effect of the tide depth.
