Yusufeli Dam - Design

Design

Situated 70 kilometres (Bad rounding here43 mi) southwest of Artvin, the Yusufeli will be a rock-fill embankment dam with a height of 270 m (886 ft) from its foundation and 223 m (732 ft) from the river's thalweg (lowest point of river bed). It will have a crest length of 410 m (1,345 ft) and crest width of 15 m (49 ft) while being composed of 2,240,000 m3 (79,104,853 cu ft) of fill.

The dam's crest will sit at an altitude of 719 m (2,359 ft) above sea level while the normal operating level of its reservoir will be 710 m (2,329 ft), maximum will be 712 m (2,336 ft) and the minimum 670 m (2,198 ft). The reservoir surface area of 33 km2 (13 sq mi) will have a total storage capacity of 2,130,000,000 m3 (1,726,819 acre·ft) and an active or "useful" storage of 1,080,000,000 m3 (875,570 acre·ft). The dam's spillway will be a service controlled chute type with a maximum discharge capacity of 8,000 m3/s (282,517 cu ft/s).

The dam will have an underground power station that is 110 m (361 ft) long, 21.4 m (70 ft) wide and 45.2 m (148 ft) high. Within the power station will be 3 x 180 MW vertical shaft Francis turbines.
