Hanhowuz Reservoir
Hanhowuz, also known as Khauz-Khan, is a reservoir in Ahal Province of southeastern Turkmenistan. The M37 highway passes nearby and the town of Denizhan (formerly called Hanhowuz) stands on the northwestern shore, with the city of Tejen not too far away in that direction. Hanhowuz Reservoir is a component of the Karakum Canal system and was created to attempt to control the erratic Tejen River. It plays an important role in agriculture in the region. The reservoir is named after the legendary khan Oguz Han. Hanhowuz (Khauzkhan) Reservoir was constructed in a natural depression to capture winter runoff and overflow from the canal for use later during the driest periods of summer. Phytoplankton thrive in the warm waters, as do many commercial fish—including Aral barbel, asp and catfish. In the satellite image, the Karakum Canal is the brown ribbon dropping down from the upper right corner and heading south and east from the reservoir. A portion of the canal is diverted, and ...

Oguz Han
Oghuz Khagan or Oghuz Khan (; ; ) is a legendary khan of the Turkic people and an eponymous ancestor of Oghuz Turks. Some Turkic cultures use the legend of Oghuz Khan to describe their ethnic and tribal origins. The various versions of the narrative preserved in many different manuscripts have been published in numerous languages as listed below in the references. The narratives about him are often entitled Oghuzname, of which there are several traditions, describing his many feats and conquests, some of these tend to overlap with other Turkic epic traditions such as Seljukname and The Book of Dede Korkut. The name of Oghuz Khan has been associated with Maodun, also known as Mete Han; the reason being that there is a remarkable similarity between the biography of Oghuz Khagan in the Turkic mythology and the biography of Maodun found in the Chinese historiography, which was first noticed by the Russo- Chuvash sinologist Hyacinth.Taskin V.S., ''"Materials on history of Sünnu"'', ...

Catfish
Catfish (or catfishes; order (biology), order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Catfish are common name, named for their prominent barbel (anatomy), barbels, which resemble a cat's whiskers, though not all catfish have prominent barbels or "whiskers", with some seemingly not having them. Siluriformes as a whole are Fish scale, scale-less, with neither the Armoured catfish, armour-plated nor the naked species having scales. This order of fish are Autapomorphy, defined by features of the skull and swimbladder. Catfish range in size and behavior from the three List of largest fish, largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivorous and scavenging bottom feeders, down to tiny ectoparasitic species known as the Candiru (fish), candirus. In the Southern United States, catfish species may be known by a variety of slang names, such as "mud cat", " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asp (fish)
The asp (''Leuciscus aspius'') is a species of freshwater ray-finned fish belonging to the family Leuciscidae, which includes the daces, minnows and related fishes. This species is found in continental Europe and western Asia. Taxonomy The asp was first formally described as ''Cyprinus aspius'' by Carl Linnaeus in the 10th edition of ''Systema Naturae'' published in 1758, the type locality being given as the lakes of Sweden. It is now classified in the genus ''Leuciscus'' within the subfamily Leuciscinae of the family Leuciscidae. Etymology The asp is a member of the genus ''Leuciscus'', a name derived tautonymously from the type species' name, '' Cyprinus leuciscus''. ''Leuciscus'' is from the Greek ''leukískos'', a “white mullet” which is a diminutive of ''leukós'', meaning "white", an allusion to the silvery sides of the common dace. The specific name, ''aspius'' , is a latinisation of asp, a name derived from ''esping'' or ''esp'', which are Swedish common name ...

Barbus Brachycephalus
''Barbus'' is a genus of ray-finned fish in the family Cyprinidae. The type species of ''Barbus'' is the common barbel, first described as ''Cyprinus barbus'' and now named ''Barbus barbus''. ''Barbus'' is the namesake genus of the subfamily Barbinae, but given their relationships, that taxon is better included in the Cyprininae at least for the largest part (including the type species of ''Barbus''). Description and uses Their common names – barbs and barbels – refer to the fact that most members of the genera have a pair of barbels on their mouths, which they can use to search for food at the bottom of the water. Barbels are often fished for food; in some locations they are of commercial significance. The roe of barbels is poisonous, however. The large ''Barbus'' barbs are also often eaten in their native range. The smaller barbs are in some cases traded as aquarium fish. Some are quite significant, but as a whole, the genus is not yet as well represented in aqua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytoplankton
Phytoplankton () are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater Aquatic ecosystem, ecosystems. The name comes from the Greek language, Greek words (), meaning 'plant', and (), meaning 'wanderer' or 'drifter'. Phytoplankton obtain their energy through photosynthesis, as trees and other plants do on land. This means phytoplankton must have light from the sun, so they live in the well-lit surface layers (euphotic zone) of oceans and lakes. In comparison with terrestrial plants, phytoplankton are distributed over a larger surface area, are exposed to less seasonal variation and have markedly faster turnover rates than trees (days versus decades). As a result, phytoplankton respond rapidly on a global scale to climate variations. Phytoplankton form the base of marine and freshwater food webs and are key players in the global carbon cycle. They account for about half of global photosynthetic activity and at least half o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bradt Travel Guides
Bradt Travel Guides is a publisher of travel guides founded in 1974 by Hilary Bradt and her husband George, who co-wrote the first Bradt Guide on a river barge on a tributary of the Amazon. Since then Bradt has grown into a leading independent travel publisher, with growth particularly in the last decade. It has a reputation for tackling destinations overlooked by other guide book publishers. Bradt guides have been cited by ''The Independent'' as covering "parts of the world other travel publishers don't reach", and nearly two-thirds of the guides on the publisher's list have no direct competition in English from other travel publishers. These include guides to parts of Asia, Latin America and Africa, in particular, which traditionally have not been widely covered by guidebook publishers, or do not have a long history of tourism. Bradt also has an extensive list of regional European guides to destinations such as the Peloponnese, the Vendée and the Basque Country. The guides ...

Ahal Province
Ahal Region (; from , also ) is one of five provinces of Turkmenistan. It is in the south-center of the country, bordering Iran and Afghanistan along the Kopet Dag Range. Its area is and population 886,845 (2022 census).''Statistical Yearbook of Turkmenistan 2000–2004'', National Institute of State Statistics and Information of Turkmenistan, Ashgabat, 2005. Overview In 2000, Ahal Region accounted for 14% of Turkmenistan's population, 11% of the total number of employed, 23% of agricultural production (by value), and 31% of the country's total industrial production. Ahal's agriculture is irrigated by the Karakum Canal, which stretches all the way across the province from east to west, tracking Turkmenistan's southern border. Another water source is the Tejen River, which flows north from Afghanistan in the southeast corner of the province, passing through two large reservoirs south of the city of Tejen. Ahal is known for the Battle of Geok Tepe of 1881, today the site of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tejen River
The Hari River ( or ; ) or Herat River or Tejen River or Harirud is a river flowing from the mountains of central Afghanistan to Turkmenistan, where it forms the Tejen oasis and disappears in the Karakum Desert. In its lower course, the river forms a northern part of the border between Afghanistan and Iran, and a southeastern part of the border between Turkmenistan and Iran. The name of the river derives from the Old Persian word Harawaiah 'river rich in water'. In Turkmenistan, the Hari is known as the Tejen or Tedzhen river and passes close to the city of Tejen. To the ancient Greeks, it was known as the Arius. In Latin, it was known as the Tarius. History One theory suggests that the Rigvedic Sarayu and the Hari are the same river. A Buddhist monastery hand-carved in the bluff of the river Harirud existed in the first centuries during the prevalence of Buddhism. The artificial caves revealed testimony of daily life of the Buddhist monks. Course The river originates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karakum Canal
The Karakum Canal (Qaraqum Canal, Kara Kum Canal, Garagum Canal; , ''Karakumskiy Kanal'', , , ) in Turkmenistan is one of the largest irrigation and water supply canals in the world. Started in 1954, and completed in 1988, it is navigable over much of its length, and carries of water annually from the Amu-Darya River across the Karakum Desert in Turkmenistan. The canal opened up huge new tracts of land to agriculture, especially to cotton monoculture heavily promoted by the Soviet Union, and supplying Ashgabat with a major source of water. The canal is also a major factor leading to the Aral Sea environmental disaster. The Soviet regime planned to at some time extend the canal to the Caspian Sea. History The current Karakum Canal was not the first major attempt to bring the Amu-Darya water to the Karakums. In the early 1950s, construction began on the Main Turkmen Canal (), which would start at a much more northerly location (near Nukus), and run southwest toward Krasnovodsk. ...
