This study simulated tide modification phenomena by changing coastal topography around the East China Seas including Korean. Based on the previous studies suggesting tidal flat reclamation effects (Song et al., 2013) and regional difference of the observed long-term sea level trend (Lim and Chang 2018), we sequentially changed the coastal topography of Gyeonggi-bay of Korea and Jiangsu coast of China in the simulation experiments using MOHID (MOdelo HIDrodinâmico) ocean circulation model. The simulated amplitude of M2 constituent significantly increased with the tidal flat disappearance in the Yellow Sea, while it decreased in the South Sea of Korea. This result indicates that the change of coastal topographic in specific area can cause sea level change in the surrounding area as a far-field effect through tidal energy redistribution process.
