Manych Ship Canal
The Manych Ship Canal is a canal between the Black Sea lagoon the Sea of Azov and the Caspian Sea. , proposals were being considered to turn it into a larger canal known as the Eurasia Canal. If built, this would be a multipurpose water-resources system and a limb of international transport. A proposed design would deepen the canal to and widen it to . This would afford a traffic capacity of more than 75 million tons of cargo per year, and vessels could have a freight-carrying capacity of up to 10,000 tons.

Black Sea
The Black Sea is a marginal sea, marginal Mediterranean sea (oceanography), mediterranean sea lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia (country), Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is Inflow (hydrology), supplied by major rivers, principally the Danube, Dnieper and Dniester. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea, not including the Sea of Azov, covers , has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end ...

Manych River
The Manych () is a river in the Black Sea–Caspian Steppe of Southern Russia. It flows through the western and central part of the Kuma–Manych Depression. In ancient times, it was known as the Lik. A tributary of the Don, it is long, with its current source at the mouth of the Kalaus in the southwestern part of the Republic of Kalmykia. It flows through the town of Proletarsk and joins the Don in Manychskaya, east of the city of Rostov-on-Don.West Manych (Institute of Geography, Russian Academy of Sciences) Along the Manych, going downstream, there are: *Dam at at the mouth of the Kalaus River blocking flow eastward to East Manych *Lysyy Liman Reservoir (Dam at ) in between these two dams *A section that is almost dry * |
Fishery
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life or, more commonly, the site where such enterprise takes place ( a.k.a., fishing grounds). Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%). About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem, causing declines in some populations. Because of their economic and social importance, fisheries are governed by complex fisheries management practices and legal regimes that vary widely across countries. Historically, fisheries were treated with a " first-come, first-served" approach, but recent threats from human overfishing and environmental issues have required increased regulation of fisheries to prevent conflict and increase profitable economic activity on the fishery.

Biodiversity
Biodiversity is the variability of life, life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and Phylogenetics, phylogenetic diversity. Diversity is not distributed evenly on Earth. It is greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than one-fifth of Earth's terrestrial area and contain about 50% of the world's species. There are latitudinal gradients in species diversity for both marine and terrestrial taxa. Since Abiogenesis, life began on Earth, six major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic aeon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion. In this period, the majority of Multicellular organism, multicellular Phylum, phyla first appeared. The next 400 mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wader
245px, A flock of Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the smaller species found ...

Salinity
Salinity () is the saltiness or amount of salt (chemistry), salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to per mille, ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a state function, thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sod ...

Kuban River
The Kuban is a river in Russia that flows through the Western Caucasus and drains into the Sea of Azov. The Kuban runs mostly through Krasnodar Krai for , but also in the Karachay–Cherkess Republic, Stavropol Krai and the Republic of Adygea. The Kuban flows north and west from its source near Mount Elbrus in the Caucasus Mountains, eventually reaching Temryuk Bay in the Sea of Azov. It is navigable up to Krasnodar. Major cities on the river are Karachayevsk, Cherkessk, Nevinnomyssk, Armavir, Novokubansk, Kropotkin, Ust-Labinsk, Krasnodar and Temryuk. Despite its name, Slavyansk-on-Kuban lies not on the Kuban River, but on its distributary the Protoka. Geography and hydrology The river originates on the slopes of Mount Elbrus and forms at the merger of its two tributaries, the Ullukam and Uchkulam; from the source of the Ullukam to the delta, it has a length of . Between the source and Nevinnomyssk the river flows mostly in the deep and narrow gorge, has many th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chogray Reservoir
The Chogray Reservoir () is an artificial reservoir on the East Manych River on the border of Stavropol Krai and Kalmykia in southern Russia. The reservoir, 49 km long, was constructed in 1969–1973, primarily to satisfy the demands of local irrigated farming. Its area is 185 square km, volume 0.7 cubic km. Besides capturing water naturally brought by the tributaries of the East Manych River, the reservoir receives water from the Terek River and the Kuma River over the Kuma–Manych Canal, which was completed a few years before the reservoir. Later on, another irrigation canal – the Chernyye Zemli Main Canal (Черноземельский магистральный канал, ''Chernozemelsky magistralny kanal'') was built, taking water from the Chogray Reservoir further east and north, into Kalmykia. In 2008, after almost 40 years of operation, the reservoir was reported as in dire need of maintenance, as were many other reservoirs of its age in the area. Under ...

Stanitsa
A stanitsa or stanitza ( ; ), also spelled stanycia ( ) or stanica ( ), was a historical administrative unit of a Cossack host, a type of Cossack polity that existed in the Russian Empire. Etymology The Russian word is the diminutive of the word (), which means "station" or "police district". It is distantly related to the Sanskrit word (), which means "station", "locality", or "district". Structure The stanitsa was a unit of economic and political organisation of the Cossack peoples who lived in the Russian Empire. Each stanitsa contained several villages and khutirs. An assembly of landowners governed each stanitsa community. This assembly distributed land, oversaw institutions like schools, and elected a stanitsa administration and court. The stanitsa administration consisted of an Ataman, a collection of legislators, and a treasurer. The stanitsa court made judgements regarding "petty criminal and civil suits". All inhabitants, except for non-Cossacks, were considered me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weir
A weir or low-head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the water level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. There is no single definition as to what constitutes a weir. ''Weir'' can also refer to the skimmer found in most in-ground swimming pools, which controls the flow of water pulled into the filtering system. Etymology The word likely originated from Middle English ''were'', Old English ''wer'', a derivative of the root of the verb ''werian,'' meaning "to defend, dam". The German cognate is ''Wehr'', which means the same as English weir. Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more Navigability, navigable by boat. In ...

Hamlet (place)
A hamlet is a human settlement that is smaller than a town or village. This is often simply an informal description of a smaller settlement or possibly a subdivision or satellite entity to a larger settlement. Sometimes a hamlet is defined for official or Administrative division, administrative purposes. The word and concept of a hamlet can be traced back to Anglo-Normans, Norman England, where the Old French came to apply to small human settlements. Etymology The word comes from Anglo-Norman language, Anglo-Norman ', corresponding to Old French ', the diminutive of Old French ' meaning a little village. This, in turn, is a diminutive of Old French ', possibly borrowed from (West Germanic languages, West Germanic) Franconian languages. It is related to the modern French ', Dutch language, Dutch ', Frisian languages, Frisian ', German ', Old English ', and Modern English ''home''.
