n this study we try to identify the residual current characteristics of Seomjin River discharges to consider their physical properties using seasonal field observation during spring tide and three-dimensional numerical modeling with EFDC(Environmental Fluid Dynamics Code). A EFDC and observed data was used to predict the seasonal residual current behavior of Seomjin River discharges. The tidal elevation boundary conditions of the four main tidal harmonic(M2, S2, K1, O1) constituents on the open boundary and river discharges at the river boundary are considered in this study. The open boundary conditions are evaluated from the observation data of tide and tidal current near the open boundary. The seasonal residual current show well the three-dimensional tidal current and thermal effluents effect to the seasonal variation of river discharges.
