EUPHRATES DIVERTED VIA TWIN-BORE TUNNELS

This article describes the Sanliurfa Tunnels System, the largest civil engineering work ever undertaken in Turkey. The waters of the Euphrates, confined by the Ataturk Dam, will be diverted at the rate of 328 cubic meters/second through twin-bore tunnels each 26.4 km long with a lined diameter of 7.6 meters. The water will generate up to 2400 MW of power before being fed to the fertile but hitherto arid plains of Upper Mesopotamia. In addition to the tunnels, the underground works, started in 1977, consist of full-size cross-passages at 500-meter intervals, approximately 4 km of access tunnels and 22 ventilation shafts. Tunneling is scheduled for completion in mid-1993.
