Impact of massive coastline modification along the East China Sea coasts on decadal tidal changes

通过编制反映东海近40年来3个阶段水深的3个水深数据集，并与潮汐模型结果进行比较，研究了东海海岸线和水深的年代际变化及其对潮汐等海洋参数的影响。结果表明，渤海西部近40年来M2潮振幅变化高达20 cm，海岸开发使该地区新增陆地面积达700 km ~ 2。研究表明，在评估海洋场时，考虑到东海最近的水深变化的重要性。

Decadal changes in coastlines and bathymetries in the East China Sea and their impact on oceanic parameters such tides have been investigated by compiling three depth datasets which reflect the bathymetry at three stages in the recent four decades, and by comparing tide-model results using such data. It was found that M2 tidal amplitudes has changed as large as 20 cm during the last four decades in the western Bohai Sea, where 700 km2 of lands were newly formed as a result of the coastal development. The study indicates the importance of considering the recent bathymetric changes in the East China Sea when evaluating oceanic fields.
