This study used both RMA2 and SED2D-WES to model sedimentation after sea-dyke construction in Lake Saemangeum. The finite element mesh was created with bathymetry data obtained by the Korea Rural Community and Agricultural Corporation. The results of a TANK model of the Saemangeum Watershed were used to assign a boundary condition of inlet flow. Values from monthly measurements taken at the gauging station at Gimje and DongjinRiver3 were used to establish the upstream boundary condition for suspended sediment concentrations; those were under the jurisdiction of the Ministry of Environment of Republic of Korea. Since neither hydraulics nor sedimentation data were measured in Lake Saemangeum, accurate forecasting of sedimentation could not be calculated. As a result of the simulation, however, hydraulic conditions and spatial patterning of sedimentation areas were confirmed.
