Prediction of changes in tidal system and deltas at Nakdong estuary due to construction of Busan new port H. ~ i m ' & G.-Y. park2 1 Department of Civil & Environmental Engineering, Kookmin University, Korea 2 Hyundai Construction Company, Korea Abstract The deltas at Nakdong Estuary may experience environmental impact because of the construction of Busan Yew Port. There are several physical properties which can influence the bathymetric change at the area. The effect of the New Port on the future bathymetric changes of the deltas was examined in three main directions: the tidal current, wave and wave-induced current, and river flood. This paper describes the tidal current environment and the consequent bathymetric change before and after the construction of the Busan New Port and the Nakdong Tidal Barrage. The model results show that the new port will reduce the tidal current speed around the construction site, but not significantly influence the flows around the river mouth area. 1 Introdu
