Ilim Group
The Ilim () is a river in Irkutsk Oblast in Russia, a right tributary of the Angara. It flows north between and parallel to the rivers Angara and Lena, and then swings west to join the Angara south of Ust-Ilimsk. Geography The Ust-Ilimsk Dam on the Angara (downstream from the older, bigger, and better known Bratsk Dam), completed in the mid-1970s, not only backs up the Angara, but also the Ilim as far as Zheleznogorsk-Ilimsky. The site of the old town of Ilimsk was flooded by the reservoir. The Ilim is long, and its basin covers . The river freezes up in late October and stays icebound until early May. Its main tributaries are the Kochenga and the Tuba from the right, and the Chora from the left. |
Angara
The Angara (; ) or Angar ( мүрэн) is a major river in Siberia, which traces a course through Russia's Irkutsk Oblast and Krasnoyarsk Krai. It drains out of Lake Baikal and is the headwater tributary of the Yenisey. It is long, and has a drainage basin of . It was formerly known as the Lower or Nizhnyaya Angara (distinguishing it from the Upper Angara). Below its junction with the Ilim, it was formerly known as the Upper Tunguska (, ''Verhnyaya Tunguska'', distinguishing it from the Lower Tunguska) and, with the names reversed, as the Lower Tunguska. Course Leaving Lake Baikal near the settlement of Listvyanka, the Angara flows north past the Irkutsk Oblast cities of Irkutsk, Angarsk, Bratsk, and Ust-Ilimsk. It then crosses the Angara Range and turns west, entering Krasnoyarsk Krai, and joining the Yenisey near Strelka, south-east of Lesosibirsk.

River
A river is a natural stream of fresh water that flows on land or inside Subterranean river, caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the Runoff (hydrology), runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their Bank (geography), banks and flood the surrounding area, spreading nutrients to the surrounding area.

Lena River
The Lena is a river in the Russian Far East and is the easternmost river of the three great rivers of Siberia which flow into the Arctic Ocean, the others being Ob (river), Ob and Yenisey. The Lena River is long and has a capacious drainage basin of ; thus the Lena is the list of rivers by length, eleventh-longest river in the world and the longest river entirely within Russia.

Course The Lena originates at of elevation in the Baikal Mountains, west of Lake Baikal, south of the Central Siberian Plateau. The Lena flows north-east and traverses the Lena-Angara Plateau, then is joined by three tributary rivers: (i) the Kirenga, (ii) the Vitim (river), Vitim, and (iii) the Olyokma. From Yakutsk, the Lena River enters the Central Yakutian Lowland and flows north until joined by the eastern tributary, the Aldan (river), Aldan River, and the western tributary, the ...

Ust-Ilimsk Dam
The Ust-Ilimsk Hydroelectric Power Station (Ust-Ilimsk HPS) is a concrete gravity dam on the Angara River and adjacent hydroelectric power station. It is located near Ust-Ilimsk, Irkutsk Oblast in Russia and is the third dam on the Angara cascades. Construction of the dam began in 1963, its reservoir began to fill in 1974, and the power plant was commissioned in 1980. History Background Between 1951 and 1955, construction of the Ust-Ilimsk HPS was designated as a priority and in September 1960, the State Commission determined the most suitable spot for the dam. It would be constructed on the Angara River, below the mouth of the Ilim River. Gidroproekt All-Union Design and Exploratory Institute produced the design of the HPS and on June 8, 1962, the Central Committee of the CPSU and Ministerial Council of the USSR determined the schedule of construction and the project's scope. Construction Construction on Stage I of the HPS began in 1963. This included preparing the dam's foundat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bratsk Dam
The Bratsk Hydroelectric Power Station (also referred to as The ''50 years of Great October'' Dam) is a concrete gravity dam on the Angara River and adjacent hydroelectric power station. It is the second level of the Angara River hydroelectric station cascade in Irkutsk Oblast, Russia. From its commissioning in 1966, the station was the world's single biggest power producer until Krasnoyarsk Hydroelectric Power Station reached 5,000 MW (at 10 turbines) in 1971. Annually the station produces 22.6 TWh. Currently, the Bratsk Power Station operates 18 hydro-turbines, each with capacity of 250 MW, produced by the Leningrad Metal Works ("LMZ", , ) in the 1960s. Design and specifications Dam Components: * concrete wall 924 m long and 124.5 m high at its maximum (stationary part 515 m long, waterdrop part 242 m long, dumb part 167 m). * by-wall house 516 m long * riverbank concrete walls all 506 m long * right bank ground wall 2 ...

Ilimsk
Ilimsk () was a small town in Siberia, within today's Irkutsk Oblast of Russia. The town was flooded by the Ust-Ilimsk Reservoir in the mid-1970s. Ilimsk was founded in 1630 on the Ilim River, a tributary of the Angara River, as Ilimsky Ostrog (i.e., "Fort Ilim"). From here a portage ran east to the Kuta River which joins the Lena River at Ust-Kut, thereby allowing travel from the Yenisei River basin to that of the Lena River. In early times the Ilimsk Uyezd was one of the few grain-producing areas in Siberia. Around 1700 there were 280 settlements, including seven ostrogs. In 1745 there were 7,605 peasants. Much of the grain was shipped down the Lena to feed the Okhotsk Coast and other areas in eastern Siberia. Grain production shifted south as the area around Irkutsk became more settled. From 1764 to 1775 the town was the administrative center of a district (''okrug'') and had population of around 700 by the end of the 19th century. Alexander Radishchev was exiled t ...

Drainage Basin
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, " watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Soviet Encyclopedia
The ''Great Soviet Encyclopedia'' (GSE; , ''BSE'') is one of the largest Russian-language encyclopedias, published in the Soviet Union from 1926 to 1990. After 2002, the encyclopedia's data was partially included into the later ''Great Russian Encyclopedia'' in an updated and revised form. The GSE claimed to be "the first Marxist–Leninist general-purpose encyclopedia". Origins The idea of the ''Great Soviet Encyclopedia'' emerged in 1923 on the initiative of Otto Schmidt, a member of the Russian Academy of Sciences. In early 1924 Schmidt worked with a group which included Mikhail Pokrovsky, (rector of the Institute of Red Professors), Nikolai Meshcheryakov (Former head of the General Directorate for the Protection of State Secrets in the Press, Glavit, the State Administration of Publishing Affairs), Valery Bryusov (poet), Veniamin Kagan (mathematician) and Konstantin Kuzminsky to draw up a proposal which was agreed to in April 1924. Also involved was Anatoly Lunacharsky, People' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
