Madushan Dam
The Madushan Dam is a gravity dam on the Honghe (Red) River in Honghe Hani and Yi Autonomous Prefecture of Yunnan Province. The name of the dam comes from the nearby village of Madushan, located on the left bank of the river upstream from the dam. Madushan village is administratively under Manhao Town (which itself located a few kilometers downstream of the dam) of Gejiu City of Honghe Prefecture; the opposite, right bank of the river is in Jinping Miao, Yao, and Dai Autonomous County of the same Honghe Prefecture. The primary purpose of the dam is hydroelectric power production and it supports a 300 MW power station. Construction on the dam began in 2007 and its generators were commissioned in 2011.

Buildings And Structures In Honghe Hani And Yi Autonomous Prefecture
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Infrastructure Completed In 2011
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

Dams Completed In 2011
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravity Dams
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 to oppose the horizontal pressure of water pushing against it. 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 foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

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 al ...

List Of Tallest Dams In China
The tallest dams in China are some of the tallest dams in the world. Nearly 22,000 dams over in height – about half the world's total – have been constructed in China since the 1950s. Many of the tallest are located in the southwestern part of the country (Guizhou, Sichuan, Yunnan) on rivers such as the Mekong, the Yangtze, and its upper stretch (Jinsha River) and tributaries ( Yalong, Dadu, Min and Wu). The Yellow River in the western part of the country also hosts several among the tallest. Purposes for these high structures include flood control, irrigation and, predominantly, hydroelectric power. While beneficial, many throughout the country have been criticized for their effects on the environment, displacement of locals and effect on transboundary river flows. Currently, the country's and world's tallest, Jinping-I Dam, an arch dam high, is located in Sichuan. The tallest embankment dam in China is the Nuozhadu Dam in Yunnan. The country's highest gravity dam is Lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, 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.

Manhao
Manhao () is a town in Gejiu County-level city of Yunnan Province of China. History Located on the Red River, Manhao was a transhipment point of some significance prior to construction of the Kunming–Hai Phong Railway in the early 20th century, as the shortest route between Kunming and French Indochina ran through it. Manhao was considered the head of small-boat (junk, or ''wupan'' 五版) navigation on the Red River; so Yunnan's products such as tin would be brought to Manhao by pack mules, where they would be loaded to boats. In those days, to travel from Hai Phong (which was the closest sea port to Kunming) to Kunming, one would need 28 days: it involved 16 days of travel by steamer and then a small boat up the Red River to Manhao (), and then 12 days overland () to Kunming. Economy The Madushan Dam is located a few kilometers upstream from Manhao; the dame is named after the nearby Madushan Village. Two bridges span the Red River in Manhao. The high Manhao Bridge is ...
