Three Gorges Dam
The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. The dam generates an average 95±20 TWh of electricity per year, depending on annual amount of precipitation in the river basin. After the extensive monsoon rainfalls of 2020, the dam's annual production nearly reached 112 TWh, breaking the previous world record of ~103 TWh set by Itaipu Dam in 2016. The dam body was completed in 2006. The power plant of the dam project was completed and fully functional as of July 4, 2012, when the last of the main water turbines in the underground plant began production. Each main water turbine has a capacity of 700 MW. Coupling the dam's 32 main turbines with two smaller generators (50 MW each) to pow ...

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 ci ...

Sun Yat-sen Xinhai revolution 100th anniversary edition . was a Chinese politician who served as the first provisional president of the Republic of China and the first leader of the Kuomintang (Nationalist Party of China). He is called the "Father of the Nation" in the Republic of China, and the "Forerunner of the Revolution" in the People's Republic of China for his instrumental role in the overthrow of the Qing dynasty during the Xinhai Revolution. Sun is unique among 20th-century Chinese leaders for being widely revered in both Mainland China and Taiwan. Sun is considered to be one of the greatest leaders of modern China, but his political life was one of constant struggle and frequent exile. After the success of the revolution in 1911, he quickly resigned as president of the newly founded Republic of China and relinquished i ...

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the shear strength of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecological
Ecology () is the study of the relationships between living organisms, including humans, and their biophysical environment, physical environment. Ecology considers organisms at the individual, population, community (ecology), community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance (ecology), abundance, biomass (ecology), biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The ecological succession, successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecol ...

Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely follow ...

1931 China Floods
The 1931 China floods, or the 1931 Yangtze–Huai River floods, occurred from June to August 1931 in China, hitting major cities such as Wuhan, Nanjing and beyond, which eventually culminated into a dike breach along Lake Gaoyou on 25 August 1931. Fatality estimates vary widely. A field survey by the University of Nanking led by John Lossing Buck immediately after the flood found "150,000 people had '' drowned'', and that this number represented less than a quarter of all fatalities during the first 100 days of the flood." The official report found 140,000 drowned and claims that "2 million people died during the flood, having drowned or died from lack of food". A cholera epidemic in the subsequent year, from May 1932, was officially reported to have 31,974 deaths and 100,666 cases. While frequently featured in the list of disasters in China by death toll, a popular high-end estimate of 3.7 to 4.0 million fatalities is instrumental in "helping the 1931 flood to secure its ...

Yangtze Plain
The Yangtze Plain ( Chinese: 長江中下游平原/长江中下游平原; Wade-Giles: Ch'ang Chiang P'ing-yüan; Pinyin: Chang Jiang Pingyuan) is made up of a series of alluvial plains of along the Yangtze River and its major tributaries. The Yangtze Plain starts east of Yichang (Hubei province), China. The Middle Yangtze Plain is made up of parts of the north-eastern and south-eastern Hunan, Hubei, and north-central Jiangxi provinces, and includes the Dongting, Poyang, and Hong lakes. The Middle-Lower Yangtze Plain stretches eastward from Mount Wu to the coast. It is made up of alluvial deposits from the Yangtze River and its tributaries. The plain is somewhat swampy, made up of many lakes and rivers, making it suitable for rice growing and freshwater fish, and it is therefore known as the "land of fish and rice". The area also produces tea, silk, rapeseed, broad beans, and tangerines. The Lower Yangtze Plain includes the Yangtze River Delta. See also * Jiangnan ...

Electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a u ...

Water Turbine
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy. History Water wheels have been used for hundreds of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The migration from water wheels to modern turbines took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. Swirl The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβη" ...
