To investigate salinity intrusion along Seomjin river estuary, field measurements and numerical simulation have been carried out. In general, salinity in estuaries depends upon interaction processes of river discharge, tidal range and bathymetry, yielding seasoanl and tidal changes. Salinity was measured at 6 points including Songjeong, Seomjin Br., Dontak, Seornjingang Br., Gwangyang Br. and Taein Br. for spring(9 April 2004), mid(2 October 2(04), neap(28 May 2005) tides, with vessels anchored during 25 hours. Salinity was observed for high water in ranges of 0.7-12.0 PSU at the Seomjin Br. point, 21.9-32.9 PSU at the Gwangyang Br. point and 20.8-29.7 PSU of difference between 2 points. Salinity differecnes for high and low waters were obtained in ranges of 0.3-8.0 and 5.2-9.2 PSU, respectiviely, at the Seomjin Br. and Gwangyang Br. points. Mathematical experiments were undertaken using EFDC(Environmental Fluid Dynamic Computation code). The model was calibrated comparing hydrodynamic and salinity measurements with predictions. The model undershot the maximum level of 12.1 PSU at the Seomjin Br. point, which is possibly due to the inexactness of bathymetry and open boundary conditions. On the other hand, the river maintenance flow of 5.5 m3/s at Songjeong cannot reflect salinity in-situ downstream Hadong and aquatic ecosystem.
