Abstract
The purpose of this study is to find the variation of sedimentation patterns after Saemangeum reclamation. Residual flow after Saemangeum reclamation was calculated prognostically from the observed water temperature and salinity data in May 1992 by the Marine Development Institute of Gunsan National University and wind data which were obtained from spring 1969 through winter 1977 by the Kunsan Meteorological Observatory. Three dimensional movements of injected particles due to currents, turbulence and sinking velocity are tracked by the Euler-Lagrange method. When suspended sediments with the size of soil grain of 30 ㎛ are injected in the Sinsi drainage sluice, their dispersion range of sediment is around Gogunsan islands. When suspended sediments with the size of soil grain of 200 ㎛ are injected in the Garyeok drainage sluice, their dispersion range of sediment was around the Garyeok drainage sluice and Byeonsan coastal area.
