3. History of Tarbela Dam
 Tarbela Dam is one of
the world’s largest earth
and rock filled Dam.
 Greatest water
resources
The Dam is built on one
of the World’s largest
rivers – the Indus known as
the “Abbasin” or the father
of rivers

4. History of Tarbela Dam
 General consultant of
WAPDA is HAZARA
ENGINEERING COMPANY
 The World Bank
accepted Tarbela Dam
Project in 1965
Built between 1968 and
1976

5. Project Constrain
• Cost
The total cost of project including power
units (1-14) amount to US $ 2.63 billion.
• Time
– 8.3 year’s

6. The Project Main Feature
Project Consists of a 9,000 (2,743
meters) long.
 spillway capacity 6.5millan cuescs
 The dam is 469 feet (143 m) high.
 The Dam is 8,997 feet (2,743 m)
wide at its crest.
 The total spillway capacity is
1,500,000
Reservoir Aria 80km

7. Tunnels
• Total number of Tunnels 4
• Length half mile
• Tunnel 1, 2, 3 for power generation and
tunnel 4 for irrigation

8. Spillway
• Two Spillway (Service spillway auxiliary
spillway)
• Spillway is flood routing structure
• Spillways capacity is 1500,000 cusecs

9. Spillway
• Service spillway has 44% of total capacity
• Discharge capacity of service spillway is
650,000 cusecs.
• Discharge capacity of auxiliary spillway is
850,000 cusecs.

10. Power Generation
Four power units of 175 MW installed on each
of the tunnels 1, 2, and 3.
The project has thus been enhanced from
2100 MW, as originally planned to 3478 MW.
