Underground Hydropower Plants

open access: yes, 2022
Most of the hydropower plants developed in a mountainous topography consist different underground structures such as headrace tunnels, pressure tunnels and shafts, powerhouse caverns, tailrace, and access tunnels. Design of underground structures in a cost effective and optimum way is a challenge and demands step wise investigations on the engineering ...

Environmental costs of hydropower plants [PDF]

open access: yesWIT Transactions on Ecology and the Environment, Vol 98, 2006
The balance between human activity and the environment has been destroyed for some time because of rapid development in all parts of the world. The coexistence of development and the environment is achieved by technical and economic approaches. The technical approach takes into account such factors as air pollution measures, conserving energy, and ...
