Orlovka (Mamyn)
The Orlovka (russian: Орловка), also known as Mamyn (russian: Мамын), is a river in Mazanovsky District, Amur Oblast, Russia. It is the 4th longest tributary of the Selemdzha after the Byssa, with a length of and the second in drainage basin area, with . The river basin includes the Garinskoye iron ore deposit, one of the largest in the Russian Far East, as well as gold prospecting areas. The only settlement in the river basin is Oktyabrsky, located by river Gar, the main tributary. In the past there had been other settlements by the river, such as the Slava collective farm on the left bank near the mouth, but they were abandoned. History The original Tungusic name of the river was replaced in 1972 under the USSR administration at the time of the renaming of geographical sites in the Russian Far East. The name "Orlovka" honors Warrant Officer Orlov, who visited the area in 1847 to trade with the local Evenks on behalf of the Russian-American Company. In 1999, th ...

Dzhagdy Range
The Dzhagdy Range (russian: Хребет Джагды) is a range of mountains in far North-eastern Russia. Administratively it belongs partly to Amur Oblast and partly to the Khabarovsk Krai of the Russian Federation. Geography The Dzhagdy is a range in northeastern Siberia, located in the northeast of Amur Oblast and the western side of Khabarovsk Krai. It is part of the Yankan - Tukuringra - Soktakhan - Dzhagdy group of mountain ranges (which also includes the Turan Range), being the easternmost of the group. The Upper Zeya Plain lies between this alignment of ranges and the Stanovoy Range to the north.Dzhagdy // Great Soviet Encyclopedia : (in 30 vols.) / Ch. ed. A.M. Prokhorov. - 3rd ed. - M .: Soviet Encyclopedia, 1969-1978. The Dzhagdy Range is limited by the Zeya River valley to the north and west, where Zeya town is located. The Tukuringra Range joins the Soktakhan and the Dzhagdy on the area of the Zeya Dam. To the north flows the Uda River and in the south li ...

Red Deer
The red deer (''Cervus elaphus'') is one of the largest deer species. A male red deer is called a stag or hart, and a female is called a hind. The red deer inhabits most of Europe, the Caucasus Mountains region, Anatolia, Iran, and parts of western Asia. It also inhabits the Atlas Mountains of Northern Africa; its early ancestors are thought to have crossed over to Morocco, then to Algeria, Libya and Tunisia via the Strait of Gibraltar, becoming the only species of true deer (Cervidae) to inhabit Africa. Red deer have been introduced to other areas, including Australia, New Zealand, the United States, Canada, Peru, Uruguay, Chile and Argentina. In many parts of the world, the meat (venison) from red deer is used as a food source. Red deer are ruminants, characterized by a four-chambered stomach. Genetics, Genetic evidence indicates that the red deer, as traditionally defined, is a species group, rather than a single species, though exactly how many species the group includes rem ...

Nora (river)
The Nora (russian: Нора) is a river in Amur Oblast, Russia. It is the 2nd longest tributary of the Selemdzha after the Ulma, with a length of and the first in drainage basin area, with . The name originated in "nehru", the Evenki word for "grayling". The river flows across a desolate, uninhabited area. The Lower Nora Zakaznik (Нижне-Норский заказник) is a protected area for the Siberian roe deer that was established in 2010 in the lower basin of the river. Course The Nora is a right tributary of the Selemdzha. It has its origin in the southern slopes of the Dzhagdy Range. In its upper reaches the Nora flows fast among pebbles and boulders in a roughly SW direction across the Amur-Zeya Plateau. Then in its lower course it bends southwards entering a floodplain and flowing among a very marshy area dotted with lakes. Finally it meets the Selemdzha upstream from the mouth of the Orlovka (Mamyn), from the village of Norsk, Selemdzhinsky District.Google ...

Meander
A meander is one of a series of regular sinuous curves in the channel of a river or other watercourse. It is produced as a watercourse erodes the sediments of an outer, concave bank ( cut bank) and deposits sediments on an inner, convex bank which is typically a point bar. The result of this coupled erosion and sedimentation is the formation of a sinuous course as the channel migrates back and forth across the axis of a floodplain. The zone within which a meandering stream periodically shifts its channel is known as a meander belt. It typically ranges from 15 to 18 times the width of the channel. Over time, meanders migrate downstream, sometimes in such a short time as to create civil engineering challenges for local municipalities attempting to maintain stable roads and bridges.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, J.A., eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. Charlton, R., 2007. ''Fundamentals ...

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 ...

Rapids
Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence. Rapids are hydrological features between a ''run'' (a smoothly flowing part of a stream) and a ''cascade''. Rapids are characterized by the river becoming shallower with some rocks exposed above the flow surface. As flowing water splashes over and around the rocks, air bubbles become mixed in with it and portions of the surface acquire a white color, forming what is called "whitewater". Rapids occur where the bed material is highly resistant to the erosive power of the stream in comparison with the bed downstream of the rapids. Very young streams flowing across solid rock may be rapids for much of their length. Rapids cause water aeration of the stream or river, resulting in better water quality. Rapids are categorized in classes, generally running from I to VI. A Class 5 rapid may be categorized as Class 5.1-5.9. While Class I rapids are eas ...

Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...

Greater Spotted Eagle
The greater spotted eagle (''Clanga clanga''), occasionally called the spotted eagle, is a large bird of prey. Like all typical eagles, it belongs to the family Accipitridae. Its feathered legs indicate it is a member of the subfamily Aquilinae, also known as the "booted eagles".Helbig, A. J., Kocum, A., Seibold, I., & Braun, M. J. (2005). ''A multi-gene phylogeny of aquiline eagles (Aves: Accipitriformes) reveals extensive paraphyly at the genus level''. Molecular phylogenetics and evolution, 35(1), 147-164. This species was once thought to be included in the genus '' Aquila'' but now belongs to a distinct genus, '' Clanga'', along with the other two species of spotted eagles.Helbig, A. J., Seibold, I., Kocum, A., Liebers, D., Irwin, J., Bergmanis, U., Meyburg, B.-U., Scheller, W., Stubbe, M. & Bensch, S. (2005).

Mandarin Duck
The mandarin duck (''Aix galericulata'') is a perching duck species native to the East Palearctic. It is medium-sized, at long with a wingspan. It is closely related to the North American wood duck, the only other member of the genus ''Aix''. is an Ancient Greek word which was used by Aristotle to refer to an unknown diving bird, and is the Latin for a wig, derived from , a cap or bonnet. Outside of its native range, the mandarin duck has a large introduced population in the British Isles and Western Europe, with additional smaller introductions in North America. Description The adult male has a red bill, large white crescent above the eye and reddish face and "whiskers". The male's breast is purple with two vertical white bars, the flanks ruddy, and he has two orange feathers at the back (large feathers that stick up similar to boat sails). The female is similar to the female wood duck, with a white eye-ring and stripe running back from the eye, but is paler below, has a sm ...
