| Abstract: | Water is discharged from two diversion tunnels in left bank when river is closed for construction of Nuozhadu Hydropower Project.The river-closure discharge is 2 890 m3/s and the maximum flow velocity at the closure gap is 9.02 m/s.The maximum water drop at the closure gap is 8.71 m when the river is closed.In complicated conditions of topography and geology at closure dike,the river with high discharge,great drop and high velocity is successfully closed. |
