Medeu Dam
The Medeu Mudflow Control Dam ( kk, Медеу бөгеті, ''Medeý bógeti'') is a dam across the Medeu Valley south-east of Almaty, Kazakhstan, designed to protect the city from devastating debris flows (or mudflows). The mudflow threat Much of downtown Almaty is built on the alluvial fan of the Malaya Almatinka River, at the point where the river leaves the steep and narrow Medeu Valley for the wider plain. The river valley, steeply descending to the city from the Trans-Ili Alatau mountains, is highly susceptible to the formation of debris flows and/or mudflows. During the 20th century, five catastrophic debris/mudflows happened in the valleys of Malaya Almatinka, or its sister river (further west), the Bolshaya Almatinka. The most severe of them was the catastrophic mudflow of 1921 in the Malaya Almatinka valley, triggered by heavy rainfall. It killed 500 people out of Almaty's 45,000 population at the time, and destroyed much of the city. The total volume of that fl ...

Medeu
The Medeu ( kk, Медеу, ''Medeu''), is an outdoor speed skating and bandy rink. It is located in a mountain valley ( Medeu Valley, or the valley of Malaya Almatinka River) on the south-eastern outskirts of Almaty, Kazakhstan. Medeu sits 1,691 metres above sea level. It consists of 10.5 thousand square meters of ice and utilizes a sophisticated freezing and watering system to ensure the quality of the ice. History The Medeu is a high-altitude sports complex near Almaty, located at an altitude of 1691 meters above sea level. It is considered to be the world's largest high-mountain skating rink. The skating rink was named after the Maloalmatinsky volost Medeu Pusurmanov. He built three wooden huts for the wintering of his family there, and began the development of the tract in the foothills of the Zailiysky Alatau. Medeu became a well-known entrepreneur, patron of educational institutions, and participated in the planting of the city. In 1930, a sanatorium was opened in the ...

Buildings And Structures Built In The Soviet Union
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 artist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Control Projects
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting ...

Dams In Kazakhstan
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 used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mikhail Lavrentyev
Mikhail Alekseevich Lavrentyev (or Lavrentiev, russian: Михаи́л Алексе́евич Лавре́нтьев) (November 19, 1900 – October 15, 1980) was a Soviet mathematician and hydrodynamicist. Early years Lavrentiev was born in Kazan, where his father was an instructor at a college (he later became a professor at Kazan University, then Moscow University). Lavrentiev entered Kazan University, and, when his family moved to Moscow in 1921, he transferred to the Department of Physics and Mathematics of Moscow University. He graduated in 1922. He continued his studies in the university in 1923-26 as a graduate student of Nikolai Luzin. Although Luzin was alleged to plagiarize in science and indulge in anti-Sovietism by some of his students in 1936, Lavrentiev did not participate in the notorious political persecution of his teacher which is known as the Luzin case or Luzin affair. In fact Luzin was a friend of his father. Mid career In 1927 Lavrentiev spent half a ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonium Nitrate
Ammonium nitrate is a chemical compound with the chemical formula . It is a white crystalline salt consisting of ions of ammonium and nitrate. It is highly soluble in water and hygroscopic as a solid, although it does not form hydrates. It is predominantly used in agriculture as a high-nitrogen fertilizer.Karl-Heinz Zapp "Ammonium Compounds" in ''Ullmann's Encyclopedia of Industrial Chemistry'' 2012, Wiley-VCH, Weinheim. Global production was estimated at 21.6 million tonnes in 2017. Its other major use is as a component of explosive mixtures used in mining, quarrying, and civil construction. It is the major constituent of ANFO, a popular industrial explosive which accounts for 80% of explosives used in North America; similar formulations have been used in improvised explosive devices. Many countries are phasing out its use in consumer applications due to concerns over its potential for misuse. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medeu Tract
The Medeu gorge ( Russian: Урочище Медеу, '' tr. urochishe medeu'') is a territory located in the valley of Malaya Almatinka River, in foothills of Trans-Ili Alatau ridge at an altitude of 1520–1750 meters, 14 km to the southeast of center of Almaty. The natural boundaries of gorge territory are: Kimasar mountain spur separating the basins of and Butakovka rivers, to the east - Kabyrgatau separating the gorges of Kimasar and Sarysai rivers, to the south-west - Kumbel peak. On territory of the gorge in 1966 a mudflow protection Medeu Dam was built, below which is located the Medeu high-mountain sports complex. The Medeo hotel was formerly located near the Medeu rink, until it was demolished in the early 2000s. Geographic features The geographical location of the Medeu gorge, located in a forest-steppe and mountain-forest zones of the Trans-Ili Alatau ridge, determined its mountain climatic characteristics.
