The lower stretch of the river downstream of Nanjing could be divided into two parts at the place where Jiangyin bridge locates. This paper demonstrates appropriate design vessel-types for navigation, designed navigational standards and desired geometry and dimensions of channels along the river in connection with physical conditions and engineering restrictions, demands of ports and local economic development and the sailing requirements of larger ships. It proposes the principle on value-taking for desired geometry and dimensions of deepwater channels and further gives mended values in the main secti
