Tarbela Dam on the River Indus was commissioned in the mid-1970s primarily as a water resource reservoir for irrigation and was at that time the largest rock and earth-fill dam in the world.

During Tarbela’s subsequent operation, its role in providing hydropower generation has become more significant. As a result, successive hydropower stations have been added to the water release tunnels over the last few decades.

The presenters will discuss:

  • The arrangement for the 5th Extension Hydropower Project
  • Ongoing sediment management and how raised intakes are being adopted to extend the life of the reservoir
  • Construction and commissioning of the T3 and T4 raised intakes plus the plans for the T5 raised intake
  • Construction challenges and lessons learned from the 4th Extension Project and how these are being applied to the 5th Extension Project
  • Physical and CFD models of the Dal Dara channel have been used conjunctively to confirm the operability of the tailrace culvert and canal system whilst ensuring the safety of the existing spillway plunge pools
  • Recent photos from site showing the construction stage of the 5th Extension Project and comparing these to the 4th Extension Project

This meeting will be held live at the ICE (1 Great George Street, London) and also online. Refreshments will be served from 5.30pm, however, the ICE have not yet reopened the bar and therefore will be no bar facilities after the meeting.
