The Wuqiangxi Dam (Chinese :五强溪水库; pinyin :Wǔqiángxī Shuǐkù) is a gravity dam on the Yuan River in Yuanling County, Hunan Province, China. The purpose of the dam is flood control, hydroelectric power generation and navigation. [1] The dam supports a 1,200 MW power station (255 MW firm power) along with a three-stage ship lock. Initial construction on the dam began in September 1986 and construction on the dam's structures began in December 1989. All five generators were operational in December 1996. [2] [3]

Chinese language family of languages

Chinese is a group of related, but in many cases not mutually intelligible, language varieties, forming the Sinitic branch of the Sino-Tibetan language family. Chinese is spoken by the Han majority and many minority ethnic groups in China. About 1.2 billion people speak some form of Chinese as their first language.

Hanyu Pinyin, often abbreviated to pinyin, is the official romanization system for Standard Chinese in mainland China and to some extent in Taiwan. It is often used to teach Standard Mandarin Chinese, which is normally written using Chinese characters. The system includes four diacritics denoting tones. Pinyin without tone marks is used to spell Chinese names and words in languages written with the Latin alphabet, and also in certain computer input methods to enter Chinese characters.

Gravity dam

A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by primarily using the weight of the material alone to resist the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable, independent of any other dam section.
