Ulma (river)
The Ulma (russian: Ульма) is a river in Mazanovsky District, Amur Oblast, Russia. It is the longest tributary of the Selemdzha, with a length of and with the fourth in drainage basin area, after the Orlovka and Byssa. The river flows across a largely uninhabited area except for Ulma village on its banks. It is a rafting and fishing destination. History Pottery fragments belonging to the Paleolithic Selemdzha culture (SLM) were found at the archaeological site Ust-Ulma-1 by the river. Organic content in a potsherd found at the site was dated back to between 8,900 and 12,590 years ago. In 1981, the Ulma Zakaznik (Ульминский заказник), a protected area of , was established in the middle basin of the river. Course The Ulma is a left tributary of the Selemdzha. It has its origin at the confluence of the Right Ulma and Left Ulma (Bordak) in the western slopes of the Turan Range. The river flows fast in a roughly southwestern direction in its upper reaches ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turan Range
The Turan Range (russian: Хребет Тура̀на) 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. History The range was formerly a remote area, first explored by Peter Carl Ludwig Schwarz during the East Siberian Expedition of 1855. It was mapped by Arseniy Usoltsev together with geological engineer Pyotr Gorlov in 1958. A railway tunnel of the Baikal–Amur Mainline was built across the range. Geography The Turan is a range in northeastern Siberia, located in the southeastern end of Amur Oblast and the southwestern side of Khabarovsk Krai. It is part of the Yankan - Tukuringra - Soktakhan - Dzhagdy group of mountain ranges. Its ridges have a massive look, with rounded mountaintops.Турана // |
Oxbow Lake
An oxbow lake is a U-shaped lake or pool that forms when a wide meander of a river is cut off, creating a free-standing body of water. In South Texas, oxbows left by the Rio Grande are called '' resacas''. In Australia, oxbow lakes are called billabongs. The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream. Geology An oxbow lake forms when a meandering river erodes through the neck of one of its meanders. This takes place because meanders tend to grow and become more curved over time. The river then follows a shorter course that bypasses the meander. The entrances to the abandoned meander eventually silt up, forming an oxbow lake. Because oxbow lakes are stillwater lakes, with no current flowing through them, the entire lake gradually silts up, becoming a bog or swamp and then evaporating completely. When a river reaches a low-lying plain, often in its final course to the sea or a lake, it meanders wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Rivers Of Russia
Russia can be divided into a European and an Asian part. The dividing line is generally considered to be the Ural Mountains. The European part is drained into the Arctic Ocean, Baltic Sea, Black Sea, and Caspian Sea. The Asian part is drained into the Arctic Ocean and the Pacific Ocean. Notable rivers of Russia in Europe are Volga (which is the longest river in Europe), Pechora, Don, Kama, Oka and the Northern Dvina, while several other rivers originate in Russia but flow into other countries, such as the Dnieper and the Western Dvina. In Asia, important rivers are the Ob, the Irtysh, the Yenisei, the Angara, the Lena, the Amur, the Yana, the Indigirka, and the Kolyma. In the list below, the rivers are grouped by the seas or oceans into which they flow. Rivers that flow into other rivers are ordered by the proximity of their point of confluence to the mouth of the main river, i.e., the lower in the list, the more upstream.

Esox
''Esox'' is a genus of freshwater fish commonly known as pike or pickerel. It is the type genus of the family Esocidae. The type species of the genus is ''Esox lucius'', the northern pike. ''Esox'' has been present in Laurentia (which later became North America) and Eurasia since the Paleocene. Modern large pike species are native to the Palearctic and Nearctic realms, ranging across Northern America and from Western Europe to Siberia in North Asia. Pikes have the elongated, torpedo-like shape typical of predatory fishes, with sharply pointed heads and sharp teeth. Their coloration is typically grey-green with a mottled or spotted appearance with stripes along their backs, providing camouflage among underwater weeds, and each individual pike marking patterns are unique like fingerprints. Pikes can grow to a maximum recorded length of , reaching a maximum recorded weight of . Etymology The generic name ''Esox'' (pike fish) derives from the Greek ἴσοξ (''ee-soks'', a ...

Floods
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 in some of t ...

Water Runoff
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water co ...
