Northern River Reversal
The Northern river reversal or Siberian river reversal was an ambitious project to divert the flow of the Northern rivers in the Soviet Union, which "uselessly" drain into the Arctic Ocean, southwards towards the populated agricultural areas of Central Asia, which lack water. Research and planning work on the project started in the 1930s and was carried out on a large scale in the 1960s through the early 1980s. The controversial project was abandoned in 1986, primarily for environmental reasons, without much actual construction work ever done. Development of the river rerouting projects The project to turn Siberian rivers goes back to the 1830s, when tsarist surveyor Alexander Shrenk proposed it"Making Rivers Run Backward" Time U.S., Frederic Golden; By Frederic Golden, reported by: Erik Amfitheatr, Mon ...

Russland Dawydow
Russia, or the Russian Federation, is a country spanning Eastern Europe and North Asia. It is the largest country in the world, and extends across eleven time zones, sharing land borders with fourteen countries. Russia is the most populous country in Europe and the ninth-most populous country in the world. It is a highly urbanised country, with sixteen of its urban areas having more than 1 million inhabitants. Moscow, the most populous metropolitan area in Europe, is the capital and largest city of Russia, while Saint Petersburg is its second-largest city and cultural centre. Human settlement on the territory of modern Russia dates back to the Lower Paleolithic. The East Slavs emerged as a recognised group in Europe between the 3rd and 8th centuries CE. The first East Slavic state, Kievan Rus', arose in the 9th century, and in 988, it adopted Orthodox Christianity from the Byzantine Empire. Kievan Rus' ultimately disintegrated; the Grand Duchy of Moscow led the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radioactive Fallout
Nuclear fallout is residual radioactive material that is created by the reactions producing a nuclear explosion. It is initially present in the radioactive cloud created by the explosion, and "falls out" of the cloud as it is moved by the atmosphere in the minutes, hours, and days after the explosion. The bulk of the radioactivity from nuclear fallout comes from fission products, which are created by the nuclear fission reactions of the nuclear device. Un-fissioned bomb fuel (such as plutonium and uranium), and radioactive isotopes created by neutron activation, make up a smaller amount of the radioactive content of fallout. The amount of fallout and its distribution is dependent on several factors, including the overall yield of the weapon, the fission yield of the weapon, the height of burst of the weapon, and meteorological conditions. Fallout can have serious human health consequences on both short- and long-term time scales, and can cause radioactive contamination far aw ...

Nuclear Explosions For The National Economy
Nuclear Explosions for the National Economy (; sometimes referred to as ''Program #7'') was a Soviet program to investigate peaceful nuclear explosions (''PNEs''). It was analogous to the United States program '' Operation Plowshare'', although the Soviet one consists of 124 tests. One of the better-known tests was '' Chagan'' of January 15, 1965. Radioactivity from the Chagan test was detected over Japan by both the U.S. and Japan in apparent violation of the 1963 Partial Test Ban Treaty (PTBT). The United States complained to the Soviets, but the matter was dropped. History In November 1949, shortly after the test of their first nuclear device on September 23, 1949, Andrey Vyshinsky, the Soviet representative to the United Nations, delivered a statement justifying their efforts to develop their own nuclear weapons capability. He said: However the USSR did not immediately follow the U.S. lead in 1958 in establishing a program. Presumably, their position in support of a compr ...

Pechora–Kama Canal
The Pechora–Kama Canal (), or sometimes the Kama–Pechora Canal, was a proposed canal intended to link the basin of the Pechora River in the north of European Russia with the basin of the Kama, a tributary of the Volga. Completion of this project would integrate the Pechora into the system of waterways of European Russia, centered on the Volga – something that was of importance before the advent of railways, or before the first railway reached the Pechora in the 1940s. Later the project was proposed mostly to transfer Pechora's water to the Volga and further on to the Caspian Sea. 19th century proposals In the 19th century, communication between the Kama and the Pechora was conducted mostly over a 40-km portage road between Cherdyn and Yaksha. There was also an option to use very small boats that could go up the uppermost reaches of Kama and Pechora tributaries, and cart the goods over the 4 km portage remaining. Poor river and road conditions made transportation into a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caspian Sea
The Caspian Sea is the world's largest inland body of water, described as the List of lakes by area, world's largest lake and usually referred to as a full-fledged sea. An endorheic basin, it lies between Europe and Asia: east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau. It covers a surface area of (excluding the highly saline lagoon of Garabogazköl to its east), an area approximately equal to that of Japan, with a volume of . It has a salinity of approximately 1.2% (12 g/L), about a third of the salinity of average seawater. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast. The name of the Caspian Sea is derived from the ancient Iranian peoples, Iranic Caspians, Caspi people. The sea stretches from north to south, with an average width of . Its gr ...

Aral Sea
The Aral Sea () was an endorheic lake lying between Kazakhstan to its north and Uzbekistan to its south, which began shrinking in the 1960s and had largely dried up into desert by the 2010s. It was in the Aktobe and Kyzylorda regions of Kazakhstan and the Karakalpakstan autonomous region of Uzbekistan. The name roughly translates from Mongolic and Turkic languages to "Sea of Islands", a reference to the large number of islands (over 1,100) that once dotted its waters. The Aral Sea drainage basin encompasses Uzbekistan and parts of Afghanistan, Iran, Kazakhstan, Kyrgyzstan, Tajikistan, and Turkmenistan. Formerly the third-largest lake in the world with an area of , the Aral Sea began shrinking in the 1960s after the rivers that fed it were diverted by Soviet irrigation projects. By 2007, it had declined to 10% of its original size, splitting into four lakes: the North Aral Sea, the eastern and western basins of the once far larger South Aral Sea, and the smaller intermediate ...

Irrigation
Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the olde ...

Environmental Impact Study
Environmental impact assessment (EIA) is the assessment of the environmental consequences of a plan, policy, program, or actual projects prior to the decision to move forward with the proposed action. In this context, the term "environmental impact assessment" is usually used when applied to actual projects by individuals or companies and the term "strategic environmental assessment" (SEA) applies to policies, plans and programmes most often proposed by organs of state. It is a tool of environmental management forming a part of project approval and decision-making. Environmental assessments may be governed by rules of administrative procedure regarding public participation and documentation of decision making, and may be subject to judicial review. The purpose of the assessment is to ensure that decision-makers consider the environmental impacts when deciding whether or not to proceed with a project. The International Association for Impact Assessment (IAIA) defines an environ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
