The volume transport and turnover time of the Deukryang Bay, located at the southern area of Korea, were calculated based on the current meter(RCM-7,ACM 16M) data observed at the three gateways of the Bay in May and October of 1996. Dominant tidal current component was calculated through harmonic analysis from raw data to estimate influence tidal current and also residual current was measured by integrating observed data and then averaging on time.
Maximum speed of current was about 100㎝/sec during the spring tide at the waterway between Kumdangdo and Kogumdo. The total water volume transports through three entrances of the bay in May and October were 3.9×10^-2 Sv, 3.4×10^-2 Sv(1Sv=10^6㎥s^-1) and turnover time were 0.97day, 1.12day, respectively. Semidiurnal tides were predominant (70∼85%). The water volume transports by residual currents were 2∼4% of total water volume transports.
The average fraction of fresh water calculated by tidal prism method using salinity difference between inflow current and outflow current through three entrances in Deukryang Bay was about 0.06% of total volume and the flushing time of fresh water was estimated as 0.97day.
