Spatial and Temporal Variability of Residual Current and Salinity Distribution according to Freshwater Discharge during Monsoon in Nakdong River Estuary

摘要

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.
