Shuangjiangkou Dam
Design
The Shuangjiangkou Dam, when completed, will be a 312 m-high (1,024 ft) (314 m (1,030 ft) from the foundation) and 648.66 m-long (2,128 ft) rock-fill dam with a relatively impervious core. The dam's crest width will be 16 m (52 ft), its elevation 2,510 m (8,235 ft) above sea level. It will have a structural volume of approximately 44,000,000 m (1.553845336×10 cu ft). The dam will sit at the head of a 39,330 km (15,185 sq mi) drainage basin and have a reservoir capacity of 3,135,000,000 m (2,541,586 acre⋅ft) of which 2,151,000,000 m (1,743,844 acre⋅ft) is regulating or active (useful) storage. Normal reservoir elevation will be 2,500 m (8,202 ft) and minimum 2,420 m (7,940 ft). Flood elevations range between 2,501 and 2,504 m (8,205 and 8,215 ft). The dam's power station will contain four 500 MW Francis turbine-generators for an installed capacity of 2000 MW. Firm capacity of the power station is expected to be 503 MW along with the station operating for 4064 hours each year. The power station's design flow is 1,090 m/s (38,493 cu ft/s) and the mean hydraulic head 226.4 m (743 ft).
