Abstract: There exist several scouring channels (Jin Shan, Qunagongting, Zhaou etc.) westward fromJin Shan in northern Hangzhou Bay. Their depth is about 20-50m, with a total lengtli morethan 50km. The scouring channels are developed at the top of Quaternary loose sedimentlayer, and they are formed gradually by the action of strong tidal current. The variation oftheir northern slope is small in recent 30 years.Their main channel and southern slope aremuch erosion, with seasonal variations.The sediments of northern Hangzhou Bay come mainly from the Changjiang estuary.The volume of annual sediments up stream Jin Shan amounts +10 -20 million tons. Thechange of erosion-deposition is small. The erosion is in equilibrium with the deposition. Butthe scouring channel evolution has still the possibilities to extend both in length and in width.
