In this study, the flow reversal and salinity distribution associated with tidal effects were investigated at a macro-tidal estuary located in tidal range of the Yellow Sea in South Korea. A 2-D hydrodynamic model (RMA-2) and a 2D advectiondispersion model (RAM4) were employed to simulate flow behavior and salinity distribution, respectively. The results showed that reverse flow occurred five times over 3-day period and the maximum reverse flow extended over 32.9 km upstream. Salinity distribution was obtained by estimating the salinity input with analytical solution of advection-dispersion equation. The total length of the saline wedge calculated from numerical simulation was in agreement with that obtained from an empirical formula.
