Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 2002-02-01 Abstract The periodic shifting of the bifurcation point of the North Channel and South Channel of the Yangtze river is very important in the estuary. The North Channel is bifurcated from the South Branch by cutting a channel through the submerged sandbanks. Once a bifurcation channel is formed, the differences in flow conditions of the two waterways make it change rapidly and very unstable: the bifurcation point shifts gradually downstream and the bifurcation channel rotates conterclockwise, thus increasing the flow resistance to flow and accelerating the process of channel sedimentation. The range of migration of bifurcation point may reach 20 km or more. When the channel is silted up to such an extent that it is impossible to accommodate the river flow, a new bifurcation channel will be formed at a certain distance upstream. Such changes in the flow field and the channel pattern bring much trouble to navigation. The two channels, as well as the North Passage and South Passage, are all very wide, ranging from several km to more than ten km, and shoals can be found here and there in the passages and channels. The periodic shifting of the bifurcation point influences all these waterways.
