| Abstract: | Combined with the hydraulic model experimental results about the third-phase river closure on the open diversion channel at the Three Gorges project for last several years, the hydraulic problems including water diversion conditions and water head of river closure, choice of methods of river closure, function of roughening sill in the closure gap, river closure in advance, and how to reduce the difficulties in river closure, etc. are analyzed and discussed. The hydraulic conditions for the third-phase river closure scheme purposed to be implemented are presented and recommendations have been made for its feasibility. |
