Geheyan
The Geheyan Dam () is an arch-gravity dam on the Qingjiang River, a tributary of the Yangtze River, in Hubei, China. The dam is located in Changyang Tujia Autonomous County (which is part of the prefecture-level city of Yichang), just a few kilometers to the west (upstream) from the county seat, Longzhouping Town (). The dam was designed in 1987, and is equipped with a ship lift capable of lifting vessels of displacement. The dam played an important role in helping to ameliorate the impact of the 1998 Yangtze Floods. Power is generated by four units rated at each, totalling the installed capacity at . 1998 Qing River Highest Water Level.JPG, 1998 Yangtze River floods Qing River Geheyan Dam Highest Water Level,203.94 m, Geheyan Dam crest elevation is 206 m.

Qingjiang River
The Qing River () is a right (southern) tributary of the Yangtze River (Chang Jiang) in Hubei province of south-central China., Geography Course The Qing River Headwaters originate at Tenglong Cave (Teng Long Dong) near Lichuan City, in Hubei's southwestern corner. The river is long. Its drainage area is 17,000 km², occupying large portions of the Enshi Tujia and Miao Autonomous Prefecture and Yichang Prefecture-level city. The Qing River (Qing Jiang) confluence with the Yangtze River (Chang Jiang) is at the ancient city of Yidu in the Yichang Prefecture of Hubei. Dams The Qing River has three large dams on it: the Geheyan Dam, Gaobazhou Dam, and Shuibuya Dam. The Geheyan Dam has a ship lift that can lift vessels of up to 300 tons displacement, to allow water transport upriver from the dam. During the 1998 Yangtze River floods the dam effectively held back the Qing River (Qing Jiang) flow. There is also the Dongping Dam The Dongping Dam is an arch dam on ...

Changyang Tujia Autonomous County
Changyang Tujia Autonomous County () or in Tujia language known as ''Changryangf Bifzivkar Zivzirxianf'' is an autonomous county in western Hubei province, People's Republic of China. It is under the administration of the prefecture-level city of Yichang. The county is located in the basin of the Qing River, a right tributary of the Yangtze. The river is flanked by mountains on both sides, the tallest of which - the Tianzhu Mountain - is tall. The river is dammed by the Geheyan Dam (located within the county) and the Gaoba Dam (located in the neighboring Yidu, Hubei, Yidu County-level City, but flooding some of the Qingjiang River valley within Changyang County as well). The resulting reservoirs provide the main water transportation route throughout much of the county. Established in 1984 with a surface area of and a population in 1984 of 399,000 inhabitants, of which 295,000 were Tujia.

Dams In China
Dams and reservoirs in China are numerous and have had a profound effect on the country's development and people. According to the World Commission on Dams in 2000, there were 22,104 dams over the height of operating in China. Of the world's total large dams, China accounts for the most – of them; of which are used for irrigation. Accordingly, the oldest in China still in use belongs to the Dujiangyan Irrigation System which dates back to 256 BC. In 2005, there were over 80,000 reservoirs in the country and over 4,800 dams completed or under construction that stands at or exceed in height. As of 2007, China is also the world's leader in the construction of large dams; followed by Turkey, and Japan in third. The tallest dam in China is the Jinping-I Dam at , an arch dam, which is also the tallest dam in the world. The largest reservoir is created by the Three Gorges Dam, which stores 39.3 billion m3 (31,900,000 acre feet) of water and has a surface area of . Three Gorges is ...

Yichang
Yichang (), alternatively romanized as Ichang, is a prefecture-level city located in western Hubei province, China. It is the third largest city in the province after the capital, Wuhan and the prefecture-level city Xiangyang, by urban population. The Three Gorges Dam is located within its administrative area, in Yiling District. History In ancient times Yichang was known as Yiling. Historical records indicate that in the year 278 BC, during the Warring States period, the Qin general Bai Qi set fire to Yiling. In 222 AD Yichang was also the site of the Battle of Yiling, during the Three Kingdoms Period. Under the Qing Guangxu Emperor, Yichang was opened to foreign commerce as a trading port after the Qing and Great Britain agreed to the Chefoo Convention, which was signed by Sir Thomas Wade and Li Hongzhang in Chefoo on 21 August 1876. The imperial government set up a navigation company there and began building facilities. Since 1949, more than 50 wharves (with a total ...

Arch-gravity Dam
An arch-gravity dam or arched dam is a dam with the characteristics of both an arch dam and a gravity dam. It is a dam that curves upstream in a narrowing curve that directs most of the water pressure against the canyon rock walls, providing the force to compress the dam. It combines the strengths of two common dam forms and is considered a compromise between the two. They are made of conventional concrete, roller-compacted concrete (RCC), or masonry. Arch-gravity dams are not reinforced except at the spillway. A typical example of the conventional concrete dam is the Hoover Dam. Changuinola Dam is an example of the RCC arch-gravity dam. A gravity dam requires a large volume of internal fill. An arch-gravity dam can be thinner than the pure gravity dam and requires less internal fill. Overview Arch-gravity dams are dams that resist the thrust of water by their weight using the force of gravity and the arch action. An arch-gravity dam incorporates the arch's curved desi ...

Renminbi
The renminbi (; symbol: ¥; ISO code: CNY; abbreviation: RMB) is the official currency of the People's Republic of China and one of the world's most traded currencies, ranking as the fifth most traded currency in the world as of April 2022. The yuan ( or ) is the basic unit of the renminbi, but the word is also used to refer to the Chinese currency generally, especially in international contexts. One yuan is divided into 10 jiao (), and the jiao is further subdivided into 10 fen (). The renminbi is issued by the People's Bank of China, the monetary authority of China. Valuation Until 2005, the value of the renminbi was pegged to the US dollar. As China pursued its transition from central planning to a market economy and increased its participation in foreign trade, the renminbi was devalued to increase the competitiveness of Chinese industry. It has previously been claimed that the renminbi's official exchange rate was undervalued by as much as 37.5% against its ...

Megawatt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circu ...
