Jiangya Dam
The Jiangya Dam is a concrete gravity dam on the Loushui River, located northeast of Zhangjiajie in Hunan Province, China. The primary purpose of the multi-purpose dam is flood control but it also generates hydroelectricty, supplies water for irrigation and municipal use and improves navigation. ==Background== The dam's power plant has a 300 MW capacity and generates on average 756 GWh annually. It provides for the irrigation of and water storage for about 50,000 people. The dam also reserves for flood storage and supports a 20-ton ship lift. Construction on the dam began in 1995, the first generator was operational in 1998 and the project complete in 1999. The dam was constructed with roller-compacted concrete (RCC) and is noteworthy because it was the first dam to use the slope/inclined laying process as opposed to horizontal. This technique was used from the dam's midsection upward and reduced both the cost and time of construction. The dam was constructed at a cost of about US$400 million, of which $97 million was provided by the World Bank.〔
