Danjiangkou Dam
The Danjiangkou Dam () is a concrete gravity dam on the Han river near Danjiangkou in Hubei Province, China. The original dam was constructed between 1958 and 1973. The dam creates a large Danjiangkou Reservoir. In the 21st century, the Danjiangkou Dam became part of the South-North Water Transfer Project. In 2005–2009, its height was raised in order to increase the reservoir's capacity. Heightening Originally, the dam was tall and long. Since its heightening, the dam is now tall and long. The original crest elevation was and is now . The increase in height will add to the reservoir's capacity bring it to . Currently, the reservoir has a capacity of . The dam's power plant also contains 6 x 150 MW turbine generators for an installed capacity of 900 MW. This will increase with the heightened reservoir.

Han River (Hanshui)
The Han River, also known by its Chinese names Hanshui and Hanjiang, is a major river in Central China. A left tributary of the Yangtze, the longest river in Asia, it has a length of and is the longest tributary of the Yangtze system. The river gave its name to the ancient Chinese Han dynasty, which marked one of ancient China's first golden ages and through it, to the Han Chinese, the dominant ethnic group in modern China and the most populous ethnic group in the world. It is also the namesake of the city of Hanzhong on its upper course. Geography The headwaters of the Han flow from Mount Bozhong in southwestern Shaanxi. The stream then travels east across the southern part of that province. Its highland valley—known as the Qinba Laolin—divides and is protected by the Qinling or Qin Mountains to its north and the Dabashan or Daba Mountains to its south. The main cities are Hanzhong in the west and Ankang in the east. It then enters Hubei. It crosses most of Hubei fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The reservoir can be divided in two branches, formed by the Han River and Dan River, each having a similar storage capacity. History It was constructed in 1958, and at the time it was the 3rd largest reservoirs in Asia and the largest in China. 160,000 residents were relocated to make way for the reservoir.

Megawatt
The watt (symbol: W) is the unit of Power (physics), 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 quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), 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 vo ...

Gravity Dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil. Stability of the dam primarily arises from the range of normal force angles viably generated by the foundation. Also, the stiff nature of a gravity dam structure endures differential foundation settlement poorly, as it can crack the dam structure. The main advantage to gravity dams over embankments is the scour-resistance of concrete, which protects against damage from minor over-topping flows. Unexpected large over-topping flows are still a problem, as they can scour dam foundations. A disadvantage of gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hubei Province
Hubei is a province in Central China. It has the seventh-largest economy among Chinese provinces, the second-largest within Central China, and the third-largest among inland provinces. Its provincial capital at Wuhan serves as a major political, cultural, and economic hub for the region. Hubei is associated with the historical state of E that existed during the Western Zhou dynasty (771 BCE). Its name means 'north of the lake', referring to Dongting Lake. It borders Henan to the north, Anhui and Jiangxi to the east, Hunan to the south, and Chongqing and Shaanxi to the west. The high-profile Three Gorges Dam is located at Yichang in the west of the province. History The Hubei region was home to sophisticated Neolithic cultures. By the Spring and Autumn period (770–476 BC), the territory of today's Hubei formed part of the powerful State of Chu. Chu, nominally a tributary state of the Zhou dynasty, was itself an extension of the Chinese civilization that had emerg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

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 ...

Hydroelectric Power Stations In Hubei
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.
