Tidal current power is now recognized as one of the clean power resources in Korea, where there are many strong current regions on the west and south coasts. Recently, large scale tidal devices have been deployed with a maximum rotor diameter of 18 m. These devices impose significant loading on supporting structures. In many cases, a pile fixed foundation is used to secure the structure. However, due to the high density of seawater, the drag and lift forces are much larger than in air, causing extensive stress and deflection to the pile tower structure. In this study, a numerical analysis of the hydro-forces from a rotating tidal current turbine to a tower was conducted to determine the deformation distribution along the pile tower.

After building the dyke in Nakdong River Estuary, mixing of freshwater inflow to ocean and seawater to upstream is controlled by operating the sluice gates. Mixing and convergence of seawater and freshwater by opening the sluice gates, have a major impact on the circulation of seawater in the Nakdong River Estuary. Field measurement was carried out to study the characteristics of the estuary flow and environment of each channel of the Nakdong River Estuary. Vertical salinity distribution and residual current is different from each channel by the river discharge and topographic changes.
