Adjusted scheme for two-way navigable waterway for Baota downsteam the Yangtze River

On the basis of the channel conditions and the analysis of the riverbed evolution of Bagua island in the downsteam of the Yangtze River, we calculate specifications of the special two-way navigable waterway of Baota, and carry out the waterway optimization design and adjust scheme design for the navigation marks. The adjustment satisfies the demands of two-way for different types of ships, and the development demand of the enterprises along the Yangtze River. In addition, it provides a foundation for the long-term development of this channel.
