Its length is , counting the length of the Archagyl stream at its head, and it has a drainage basin of . Yagodnoye village is located on the left bank of the Debin; the R504 Kolyma Highway crosses the river in its middle course and runs on the northern side of the river, roughly parallel to its lower course until it bends northwards near Debin. The name of the river is based on the Yakut word ''"daebin"'' (дьэбин), meaning "rust".Leontyev V.V. , Novikova K.A. ''Toponymic Dictionary of the North-East of the USSR'' / Scientific ed. G. A.

Magadan Oblast
Magadan Oblast ( rus, Магаданская область, r=Magadanskaya oblast, p=məgɐˈdanskəjə ˈobləsʲtʲ) is a federal subject (an oblast) of Russia. It is geographically located in the Far East region of the country, and is administratively part of the Far Eastern Federal District. Magadan Oblast has a population of 156,996 ( 2010 Census), making it the least populated oblast and the third-least populated federal subject in Russia. Magadan is the largest city and the capital of Magadan Oblast. The majority of the Oblast's inhabitants live in the city. The coastline has a less severe climate than the interiors, although both are very cold for its latitude. It borders Chukotka Autonomous Okrug in the north, Kamchatka Krai in the east, Khabarovsk Krai in the south and the Sakha Republic in the west. The economy is primarily based on mining, particularly gold, silver and other non-ferrous metals. History Magadan Oblast was established on December 3, 1953Decree of ...

Environmental Degradation
Environmental degradation is the deterioration of the environment (biophysical), environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. Environmental concerns can be defined as the negative effects of any human activity on the environment. The biological as well as the physical features of the environment are included. Some of the primary environmental challenges that are causing great worry are air pollution, water pollution, natural environment pollution, rubbish pollution, and so o Environmental degradation is one of the ten threats officially cautioned by the High-level Panel on Threats, Challenges and Change, high-level PaneI on Threats, Challenges and Change of the United Nations. The United Nations International Strategy for Disaster Reduction defin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airfield
An aerodrome (Commonwealth English) or airdrome (American English) is a location from which aircraft flight operations take place, regardless of whether they involve air cargo, passengers, or neither, and regardless of whether it is for public or private use. Aerodromes include small general aviation airfields, large commercial airports, and military air bases. The term ''airport'' may imply a certain stature (having satisfied certain certification criteria or regulatory requirements) that not all aerodromes may have achieved. That means that all airports are aerodromes, but not all aerodromes are airports. Usage of the term "aerodrome" remains more common in Ireland and Commonwealth nations, and is conversely almost unknown in American English, where the term "airport" is applied almost exclusively. A water aerodrome is an area of open water used regularly by seaplanes, floatplanes or amphibious aircraft for landing and taking off. In formal terminology, as defined by the ...

Floodplain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.Goudie, A. S., 2004, ''Encyclopedia of Geomorphology'', vol. 1. Routledge, New York. The soils usually consist of clays, silts, sands, and gravels deposited during floods. Because the regular flooding of floodplains can deposit nutrients and water, floodplains frequently have high soil fertility; some important agricultural regions, such as the Mississippi river basin and the Nile, rely heavily on the flood plains. Agricultural regions as well as urban areas have developed near or on floodplains to take advantage of the rich soil and fresh water. However, the risk of flooding has led to increasing efforts to control flooding. Formation Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Whereve ...

Permafrost
Permafrost is ground that continuously remains below 0 °C (32 °F) for two or more years, located on land or under the ocean. Most common in the Northern Hemisphere, around 15% of the Northern Hemisphere or 11% of the global surface is underlain by permafrost, with the total area of around 18 million km2. This includes substantial areas of Alaska, Greenland, Canada and Siberia. It can also be located on mountaintops in the Southern Hemisphere and beneath ice-free areas in the Antarctic. Permafrost does not have to be the first layer that is on the ground. It can be from an inch to several miles deep under the Earth's surface. It frequently occurs in ground ice, but it can also be present in non-porous bedrock. Permafrost is formed from ice holding various types of soil, sand, and rock in combination. Permafrost contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide, making tundra soil a carbon sink. As global war ...

Upper Kolyma Highlands
The Upper Kolyma Highlands ( rus, Верхнеколымское нагорье) is a highland area in Magadan Oblast, Far Eastern Federal District, Russia. The biggest town in the highlands is Susuman. There are large deposits of gold, tin and rare metals in the Upper Kolyma Highlands. The area is relatively less desolate than other mountainous zones of Northeastern Siberia, such as the Yukaghir Highlands or the Nera Plateau. However, some of the mining operations were deemed unprofitable following the collapse of the USSR and certain settlements of the Susumansky District lost population. Only a residual population remains in Shiroky, Kholodny and Bolshevik. Other places such as Belichan and Kadykchan have become ghost towns. The R504 Kolyma Highway crosses the southern part of the highlands. Geography The Upper Kolyma Highlands are located in the upper course of the Kolyma. They are bound in the west by the Tas-Kystabyt and Suntar-Khayata ranges and to the east by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chersky Range
The Chersky Range (, ) is a chain of mountains in northeastern Siberia between the Yana River and the Indigirka River. Administratively the area of the range belongs to the Sakha Republic, although a small section in the east is within Magadan Oblast. The highest peak in the range is tall Peak Pobeda (Chersky Range), Peak Pobeda, part of the Ulakhan-Chistay Range. The range also includes important places of traditional Yakut culture, such as Ynnakh Mountain ''(Mat'-Gora)'' and kigilyakh rock formations. The Moma Natural Park is a protected area located in the southern zone of the range. History At some time between 1633 and 1642 Poznik Ivanov ascended a tributary of the lower Lena, crossed the Verkhoyansk Range to the upper Yana and then crossed the Chersky Range to the Indigirka. The range was sighted in 1926 by Sergei Obruchev (Vladimir Obruchev's son) and named by the Russian Geographical Society after the Polish explorer and geographer Ivan Chersky (or Jan Czerski).

Placer Gold
Placer mining () is the mining of stream bed (alluvial) deposits for minerals. This may be done by open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. The metal or gemstones, having been moved by stream flow from an original source such as a vein, are typically only a minuscule portion of the total deposit. Since gems and heavy metals like gold are considerably denser than sand, they tend to accumulate at the base of placer deposits. Placer deposits can be as young as a few years old, such as the Canadian Queen Charlotte beach gold placer deposits, or billions of years old like the Elliot Lake uranium paleoplacer within the Huronian Supergroup in Canada.
