In order to investigate variation of tidal currents and tide levels due to Estuary Weir dischrage in the Mokpo Bay, the numerical model is constructed two-dimensional simple layer model, and they are analysed by the implicite finite difference method. This paper investigates the reproducivility and convergence of solution in application of the method to Mokpo castal waters, and at three stations analysed variation of tidal currents and tidal level due to Estury Weir discharge. The results of the paper is clarified ⅰ) When the amount of flowing water is maximum the variation of velocity have a rise of 2cm/sec at the front of Estury on spring tide. ⅱ) When the amount of flowing water is maximum(132cms), the variation of tidal depth have a rise of 2cm at the three station. ⅲ) Residual currents is impact of the front of Estury in spring tide.
