The Huaihe River was an independent river directly flowing into the Yellow Sea before 1128. It became a tributary of the Yellow River in 1128~1851. The lower Yellow River channel shifted to north and entered the Bohai Sea in 1855. Actually, the Huaihe River has been a tributary of the Yangtze River since 1851. At present, after going into the Hongze Lake, the Huaihe River water flows into the sea by four routes. By constructing a channel separated from the Hongze Lake along the northern coast of the lake, and deeply excavating the present Huaihe River Channel to Sea and the Huaishu River-Beiliutang River-New Yihe River channels, water would directly flow into the Yellow Sea and no longer to the Yangtze River. An annual 1000×104 t of suspended sediments (increasing by 860×104 t more than present) would deposit on the coast from Lianyungang to the Sheyang River mouth. The coastal erosion from Lianyungang to the Sheyang River mouth would be ended: the northern section would be stable and the southern section would slowly prograde, forming a new Huaihe River delta. Meanwhile, the sediments would not accumulate on the middle Huaihe River channel and Hongze Lake, and would effectively reduce inundation in the middle Huaihe River reaches.
