The Huaihe River was a big one in East China entering the Yellow Sea before 1128 A.D. It became a tributary of the Yellow River in 1128~1851 because the Yellow River lower channel greatly shifted to south and occupied the original Huaihe River channel. The Huaihe River has been a tributary of the Yangtze River since 1851, although the Yellow River changed its lower channel in 1855 and has been entered the Bohai Sea. Therefore the Huaihe River Delta is a historical delta formed in 7000 a B.P.~1128 A.D. in the North Jiangsu Plain. It is estimated that the water discharge of the Huaihe River is 497×108 m3, the suspended sediments with median size of 0.05 mm entering the Yellow Sea transported by the Huaihe River were approximately from 950×104 t/a in 7000 a B.P. increasing to 1 900×104t/a in 1128 A.D. based on the published data on the Holocene sedimentation in North Jiangsu the form, sedimentation and evolution of the Huaihe River Delta are studied in this paper.
