The Holocene Huanghe River Delta,with an area of 25,000km2,is one of the largest deltas in the world.The paper focusses on its coastal plain,including 3 younger deltas,i.e.,the delta near Tianjin,the modern delta and the aban-doned delta.In the first two deltas,land subsidence,both natural and man-induced,is serious and recent sealevel rise is mainly relative and a result of land subsidence.The major direct impacts of relative sealevel rise on the Huanghe River Delta are submergence and salinity increase.As a great part of the three younger deltas is less than 2m above sealevel,with a rising sealevel,the da-nger of submergence is great,especially during the storm surge.With a rising sea level,low-lying coastal plain will increasingly suffer from salt water int-rusion and drainage will be more difficult.Decisive action is urgently needed to avert or mitigate adverse effects.
