Atrak River
The Atrek ( fa, اترک, ku, Etrek, tk, Etrek derýasy), also known as the Attruck, Atrak, and Etrek, is a fast-moving river which begins in the mountains of north-eastern Iran (), and flows westward draining into the south-eastern corner of the Caspian Sea in Turkmenistan. Because of the high use of its waters for irrigation, it only flows into the Caspian when it is in flood stage. Geography The Atrek is long and drains a basin of . Politics Beginning at , where its tributary the Sumbar joins it, the river forms the border of Iran with Turkmenistan; this helped keep the area closed throughout the Cold War years. A 1957 treaty between Iran and the USSR assigns equal rights to 50% of the water of the frontier parts of the Atrek. The same treaty also applies to the Aras River, which now forms part of the border between Iran and Azerbaijan. Ecology Even though sturgeons concentrate in the area of the Caspian Sea next to the Turkmen coast, they do not currently migrate into th ...

Border Rivers
Borders are usually defined as geographical boundaries, imposed either by features such as oceans and terrain, or by political entities such as governments, sovereign states, federated states, and other subnational entities. Political borders can be established through warfare, colonization, or mutual agreements between the political entities that reside in those areas; the creation of these agreements is called boundary delimitation. Some borders—such as most states' internal administrative borders, or inter-state borders within the Schengen Area—are open and completely unguarded. Most external political borders are partially or fully controlled, and may be crossed legally only at designated border checkpoints; adjacent border zones may also be controlled. Buffer zones may be setup on borders between belligerent entities to lower the risk of escalation. While ''border'' refers to the boundary itself, the area around the border is called the frontier.

Landforms Of Golestan Province
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iran–Turkmenistan Border
The Iran–Turkmenistan border is 1,148 km (713 miles) in length and runs from the Caspian Sea to the tripoint with Afghanistan. The Turkmen capital Ashgabat is only 15 miles north of this boundary, and Mashhad (Iran's second largest city) is 47 miles south of it. Description The border starts at the Caspian coast just to the south of the Turkmen town of Esenguly. It then goes overland in an eastwards directions in a series of straight lines through barren salt flats for 50 km (31m) until reaching the Atrek river, the course of which it follows for 124 km (77m) to a point just south of the Turkmen village of Chat. The border then continues overland eastwards/north-eastwards across the Kopet Dag mountain range for 151 km (94m) before reaching the Sumbar river, the course of which it then follows for 41 km (26m). It then continues overland across mountain ridges in a broadly south-eastern arc for 455 km (283m) to the vicinity of the Iranian village o ...

Rivers Of Turkmenistan
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, ...

Sturgeon
Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. The earliest sturgeon fossils date to the Late Cretaceous, and are descended from other, earlier Acipenseriformes, acipenseriform fish, which date back to the Early Jurassic period, some 174 to 201 million years ago. They are one of two living families of the Acipenseriformes alongside paddlefish (Polyodontidae). The family is grouped into four genera: ''Acipenser'' (which is paraphyletic, containing many distantly related sturgeon species), ''Huso'', ''Scaphirhynchus,'' and ''Pseudoscaphirhynchus''. Two species (''Adriatic sturgeon, A. naccarii'' and ''Dabry's sturgeon, A. dabryanus'') may be extinct in the wild, and one (''Syr Darya sturgeon, P. fedtschenkoi'') may be entirely extinct. Sturgeons are native to subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America. Sturgeons are long-lived, late-maturing fishes with distinctive characteristics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
