I. BackgroundI. BackgroundWestern and Southern coasts of Korea are well known for high tides and strong tidal current.
Western coast : Tidal Power (Siwha, Garolim, Incheon)Southern coast : Tidal Current Power (Uldolmok)
Estimated wave energy resources along Korean coast is about 650MWSince 2000, KORDI has been focusing on developing technology for practical application

Tidal Barrage of 12.7km had been completed in 1994To get fresh water and reclamation Lake water was polluted by sewage and wastewaterTidal Power Plant was proposed as a counter measure in 1997 (KORDI)Basic Plan of Sihwa Tidal Power Plant was carried out in 2000 (KORDI)
Freshwater Lake was given up in 2001Feasibility Study in 2002 (KORDI / KOWACO)

Why the strong current occurs ?
Tidal range over the entire channel : avg. 3mTidal phase difference : 100min. between both endsWhich makes 2m difference in water levels and strong current
