| Abstract: | discharge Shuibuya A model experimental study is conducted on the hydraulic characteristics of the high head and large spillways with a curved inlead canal and five differential slotted flip bucket terminal structures for hydropower project. Flow pattern and flow velocity profile in the inlead canal and and measured, and as well as the jet flow behavlour is analyzed. Energy dissipation of the slotted flip bucket terminal structures is briefly discussed. spillways are observed spillways with stepped |
