Global sea level rise driven by global warming has challenged flood control of coastal regions all over the world.The average rate of rise in China's coastal areas was higher than that of global average, while sea level rise has been one of dominant threats to China's coasts.This studyprovided a comprehensive analysis on variations of tidal wave, water level caused by storm surge and water level at levee projects in China's coastal areas impacted by sea level rise.The results show that the sea level increased obviously in the tidal zone with larger amplitude and crossing region of tidal and wave.The high water level from storm surge was often higher than sea level rise with the non-linear action of storm surge and water depth.The future sea level rise in China was also projected.The high water level of Yangtze River estuary would be increased by 0.88m if global sea level would rise by 0.90m over the next 100 years.Taking Yangtze River estuary as an example, a system management strategy for flood control with overall consideration of ecosystem safety was proposed under global sea level rise.
