Core Viewpoint - The completion of emergency dredging projects in the Yangtze River has significantly improved navigation conditions and increased the navigable width of key waterways, addressing long-standing safety concerns for shipping traffic [1][2]. Group 1: Emergency Dredging Projects - The emergency dredging project in the Guanzhou waterway has increased the navigable width to 210 meters, ensuring a stable water depth of 4.5 meters during low water periods from the Zhongshui Gate to the Baoshan crossing [1]. - The dredging project in the Doulake waterway has removed underwater obstacles, increasing the navigable width from less than 150 meters to approximately 200 meters, thereby greatly enhancing the navigation capacity of the waterway [2]. Group 2: Navigation Safety Improvements - The Guanzhou waterway, which is 10.9 kilometers long and characterized by a curved and shallow structure, previously posed safety risks due to limited navigable width and shallow areas [1]. - The Doulake waterway, located in a complex navigation environment with dense terminal distribution, faced increasing threats from underwater rock piles, which have now been fully cleared to improve safety for passing vessels [2].
