The Shuangjiangkou Dam (Chinese: 双江口大坝/双江口水电站), also referred to as Shuang Jiang Kou (Chinese: 双江口), is an embankment dam currently being constructed in a gorge on the Dadu River in Sichuan Province, China. When completed, the 312 m-tall (1,024 ft) dam will be the tallest dam in the world.[2] Preliminary construction began in 2008 and the entire project was expected to be complete in 2018.[3] By April 2011, over 200,000,000 m3 (261,590,124 cu yd) of material had been excavated from the construction site.[4] In March 2013, China's Ministry of Environmental Protection approved construction on the dam's superstructure and associated facilities. The government acknowledged that the dam would have negative impacts on the environment but that developers were working to mitigate them. The dam is being built by the Guodian Group at a cost of US$4.02 billion.[5] The entire construction period is expected to last 10 years.[6] All turbines are expected to be commissioned by 2023.[7]
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 m3 (1.553845336×109 cu ft). The dam will sit at the head of a 39,330 km2 (15,185 sq mi) drainage basin and have a reservoir capacity of 3,135,000,000 m3 (2,541,586 acre⋅ft) of which 2,151,000,000 m3 (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 m3/s (38,493 cu ft/s) and the mean hydraulic head 226.4 m (743 ft).[2]
