The changes of hydraulic environment caused by construction of Saemankeum dike

새만금방조제 축조에 따른 수리환경 변화

The objective of this study is to evaluate the changes of hydraulic environment after the construction of Saemangeum sea-dikes. Numerical simulation on the tidal condition of dated 17 Apr. 1999 is performed with and without sea-dike construction status for the comparison. Results show the tidal amplitude is reducing approximately 20 cm after the construction of sea-dike during spring tide condition of 6.9 m amplitude. Currents after construction of sea-dikes along the alignment, the northern part shows 50% (inner), 90% (outer) and the southern part shows 10% (inner), 50% (outer) of the current before construction.
