An Analysis of Hydraulic Characteristics in Sea Dike Closure Gap Using a Three Dimensional Numerical Model

3차원 수치모형을 이용한 방조제 끝막이 구간의 수리특성분석(수공)

This study reviews qualitatively the flow characteristics around th tidal gap during seadike closures using a three-dimensional model for shallow water equations. The Princeton Ocean Model(POM) was adapted and applied to the Sihwa Seadike which was closed in 1994. The simulated flow patterns around the gap showed that tidal velocities increase with the cross-sectional area during ebb tide. The accelerated flow extended to wider zones passing the gap, and shock waves were generated. Vertical tidal velocity profiles were affected as the bottom scours developed beyond normal conditions.
