Baihetan Dam
The Baihetan Dam () is a large hydroelectric dam on the Jinsha River, an upper stretch of the Yangtze River in Sichuan and Yunnan provinces, in southwest China. The dam is a 289-meter-tall double-curvature arch dam with a crest elevation of 827 m, and a width of 72 m at the base and 13 m at the crest. It is considered to be the last large hydropower project in China after a series of projects starting with the Three Gorges Dam. It is also the second largest hydropower plant in the world. The hydropower station is equipped with 16 hydro-generating units that each have a capacity of 1 million kilowatts, making it the largest single-unit capacity globally. All hydro-generating units of the Baihetan hydropower station became fully operational on 20 December 2022. The dam is also part of the “world’s largest clean energy corridor”, where it joins other mega hydropower projects like the Three Gorges Dam, Wudongde Dam, Xiluodu Dam, and Xiangjiaba Dam, all located on the same riv ...

Jinsha River
The Jinsha River (, Tibetan: Dri Chu, འབྲི་ཆུ) is the Chinese name for the upper stretches of the Yangtze River. It flows through the provinces of Qinghai, Sichuan, and Yunnan in western China. The river passes through Tiger Leaping Gorge. It is sometimes grouped together with the Lancang (upper Mekong) and Nu (upper Salween) as the ''Sanjiang'' ("Three Rivers") area, part of which makes up the Three Parallel Rivers of Yunnan Protected Areas. The river is important in generating hydroelectric power, and several of the world's largest hydroelectric power stations are on the Jinsha river. Name The river was first recorded as the Hei (, ''Hēishuǐ'', lit. "Blackwater") in the Warring States' " Tribute of Yu". It was described as the Sheng ( t , s , ''Shéngshuǐ'', "Rope River") in the Han-era Classic of Mountains and Seas. During the Three Kingdoms, it was known as the Lu ( t , s , ''Lúshuǐ'').

Flood Control
Flood control methods are used to reduce or prevent the detrimental effects of flood waters."Flood Control", MSN Encarta, 2008 (see below: Further reading). Flood relief methods are used to reduce the effects of flood waters or high water levels. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Though building hard infrastructure to prevent flooding, such as flood walls, can be effective at managing flooding, increased best practice within landscape engineering is to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water. For flooding on coasts, coastal management practices have to not only handle changes water flow, but also natural processes like tides. Flood control and relief is a particularly important part of climate change adaptation and climate resilience, both sea level rise and changes in the weather (climat ...

Buildings And Structures In Zhaotong
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 artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Sichuan
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.
