Application of A Depth-Averaged Two-Dimensional Mathematical Model to Tidal Computations in the Estuary near Gunsan Port

수심평균 2차원 수학적 모형(TIFS)을 이용한 금강하구 및 연해의 조석계산

A depth-averaged two dimensional model TIFS was developed from simplified basic flow equations. The model was applied to tidal computations for the Biin Bay area near the Gunsan port. Vertical tides and tidal velocities for the tested was simulated for neap and spring tides. The simulation results were in good agreement with the obserbed data. This paper also attempts to evaluate model sensitivity from different initial conditions, roughness coefficient, time increments, and water depths. Among the selected input parameters, water depth and roughness coefficient were found to significantly affect vertical and horizontal tides.
