In-situ deformation of tunnel rock in the
headrace hydropower station.

Headrace Tunnel of Chameliya Hydroelectric Project, Nepal, Department of Geology and Mineral Resources Engineering, Norwegian University of Science and Technology, Trondheim, Norway, 2013.
Under the project the water of river Kunhar would be diverted through a weir, located near village Patrind, and a left bank conveyance system of
headrace tunnel to the right bank of river Jhelum, near the city of Muzaffarabad, where a powerhouse had been built.
The 969 MW-Neelum Jhelum Hydropower Project is scheduled to attain a major landmark, when the second Tunnel Boring Machine (TBM) will achieve breakthrough of the Right
Headrace Tunnel.

The project envisages the diversion of Neelum River water through a
Headrace Tunnel (HRT) 28.5 km and after producing power, out-falling into River Jhelum.

Headrace Channel on Vortex and Discharge coefficient.
The project will also see the
headrace from Devils Water reinstated, meaning water will once again flow to the nearby ponds and water features in the area.

The Project is considered with shorter
headrace tunnel, underground power house and long tail race tunnel/channel implying four Francis Turbines of 183 MW each unit.
In peak load between 17.00-22.00, water is channeled through
headrace tunnels and penstock to the power house underground at a height of 276 meters rated net head.
Some diversion-type hydropower stations have a fairly long
headrace tunnel, and the water inertia is very large.
