In this study, the discharge characteristics through drainage gates of Saemangeum tidal dyke were investigated by laboratory experiments, 3D numerical modelling, and field observations. Laboratory experiments conducted using a 1:50 scale model dyke, gate, seabed topography observations used to validate experimental results. From results these we derived diagrams that relate gate water levels in...
