Deepwater Navigational Channel Improvement Project of Yangtze River Estuary




The proposal combining harnessing with dredging is applied, water passage bifurcation, double jetties and spur dike are constructed, besides, dredging measures are taken to excavate and maintain the deepwater navigational channel. 141.484km dikes and dams were constructed for this project, the navigational channel's water depth which was 7m before being improved have been increased to be 8.5m, 10m and 12.5m by three phases. The bottom width of the navigational channel is 350~400m, so this project can meet all-weather two-way navigational demand of the third and fourth generation of container ship as well as 50,000T ship.
