| Abstract: | Taking the canyon section of Guangxi Datengxia hydro-junction in Qianjiang River as an example,by altering the elevation,the arrangement of variable elevation jetty and submerged type diversion pier was adopted in this paper.Then the flood route was adjusted to solve the navigation obstruction problem in middle and dry seasons,and the navigation flow condition of channel and the flood discharge condition of river in the flood period were also improved. |
| Keywords: | variable elevation jetty submerged type diversion pier navigation flow condition Datengxia hydro？鄄junction |
