Longtan Dam (Template:Zh) is a large roller-compacted concrete (RCC) gravity dam on the Hongshui River in Tian'e County of the Guangxi Zhuang Autonomous Region, China, a tributary of the Xi River and the Pearl River.[1][2][3][4][5][6] The dam is Script error: No such module "convert". high and Template:Cvt long; it is the tallest of its type in the world.[7] The dam is intended for hydroelectric power production, flood control and navigation. The dam contains seven surface spillways, two bottom outlets and an underground power station. The Longtan ship lift, part of the dam complex, will be the tallest ship lift system in the world.[8]
Construction
The dam was planned in the 1950s, but preliminary construction (roads, bridges, river diversion) did not begin until 1940s. Formal construction began on the project July 1, 2001, and the river was diverted by November 2003.[9] A total of Script error: No such module "convert". of material were excavated from the dam site.[10] Impounding of the Script error: No such module "convert". reservoir began in 2006, and the dam's first of three operational hydroelectric generating units was testing May 2007.[11] In 2009, the last generator became operational and the installed capacity increased to 6,426 MW, its annual generation is estimated at 18.7 TWh.[7]
A pair of tunnels diverted the river around the site of the dam, during construction.[12]
The dam will submerge over 300 shoals, which had rendered the upper Hongshui unnavigable.[13] The Longtan ship lift will be able to lift vessels of up to 500 tonnes.[8] Chinese officials assert the dam and ship lift will turn the Hongshui into a "golden waterway" for reaching landlocked Guizhou and Guangxi provinces.
