River Engineering Work on Nanjing Reach of Lower Yangtze River
Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 124, Issue 2
Abstract
Through construction experience and research, including model tests, on the Nanjing reach of the lower Yantze River, it was found that different methods must be used to stabilize the discharge ratio of two branches around an island, depending on the length ratio of the two branches. When the two branches have a similar length, stabilizing the upstream bends is effective. When the length of one branch is longer than the other, stabilizing the head of the island will be most effective. A subsurface stone blanket of appropriate thickness has been the most popular type of revetment because of its resistance to flow scouring. A design method to determine the thickness of a subsurface stone blanket, how to launch stone to desired positions, and other innovations for improvement of the stone blanket revetment are discussed.
