The Amu River (Tajik: дарёи Ому - Daryoi Omu, Persian: آمودریا - Âmudaryâ, Pashto: د آمو سيند - də Āmu Sind, [Amudaryo] Error: {{Lang-xx}}: text has italic markup (help), Turkmen: Amyderýa), also called Oxus River or Amudarya River, is a major river in Central Asia. It is formed by the junction of the Vakhsh and Panj rivers.
Names
Amu is said to have come from the city of Āmul, now known as Türkmenabat. Many local people refer to the river as Jayhoun (جيحون) which was thought to be a derivative of Gihon, the biblical name for one of the four rivers of the Garden of Eden or paradise.[2] The river is also known by this name to most of the medieval Islamic writers.
In classical antiquity, the river was known as the Ōxus in Latin and Ὦξος Oxos in Greek — a clear derivative of Vakhsh — the name of the largest tributary of the Amu. It was known as جيحون - Jiːħuːn or Gihun in ancient Arabic sources. Jayhun was likely influenced by Dgihun, the traditional name given to it by the people who inhabited its surrounding region.[3]
In Vayu Purana and Matsya Purana, the Oxus is mentioned as the river Chakshu, flowing through the countries of Tusharas (Rishikas?), Lampakas, Pahlavas, Paradas and Shakas etc.
Description
The river is navigable for over 1,450 km (800 miles). Its total length is 2,400 km (1,500 miles) and its drainage basin totals 534,739 square kilometres (206,464 sq mi) in area, providing a mean discharge of around 97.4 cubic kilometres (23.4 cu mi)[1] of water per year. All of the water comes from the high mountains in the south where annual precipitation can be over 1,000 mm (39 in). Even before large-scale irrigation began, high summer evaporation meant that not all of this discharge reached the Aral Sea - though there is some evidence the large Pamir glaciers provided enough melt water for the Aral to overflow during the thirteenth and fourteenth centuries A.D.
One source of the Amu River is the Pamir River, which emerges from Lake Zorkul (once also known as Lake Victoria) in the Pamir Mountains (ancient Mount Imeon), and flows west to Qila-e Panja, where it joins the Wakhan River to form the Panj River.
Another claimed source of the Amu River is an ice cave at the end of the Wakhjir valley, in the Wakhan Corridor, in the Pamir Mountains, near the border with Pakistan. A glacier turns into the Wakhan River and joins the Pamir River about 50 kilometres (31 mi) downstream[4]).
The Panj River forms the border of Afghanistan and Tajikistan. It flows west to Ishkashim where it turns north and then east north-west through the Hindu Kush passing the Tajik-Afghan Friendship Bridge. It subsequently forms the border of Afghanistan and Uzbekistan for about 200 kilometres (120 mi), passing Termez and the Afghanistan-Uzbekistan Friendship Bridge. It follows the border of Afghanistan and Turkmenistan for another 100 kilometres (62 mi) before it flows into Turkmenistan at Atamyrat. As the Amudarya, it flows across Turkmenistan south to north, passing Türkmenabat, and forms the border of Turkmenistan and Uzbekistan from Halkabat. It is then split into many waterways that used to form the river delta joining the Aral Sea, passing Urgench, Daşoguz and other cities, but it does not reach what is left of the sea anymore and is lost in the desert.
Use of water from the Amu River for irrigation has been a major contributing factor to the shrinking of the Aral Sea since the late 1950s.
Historical records state that in different periods, the river flowed into the Aral Sea (from the south), the Caspian Sea (from the east) or both, similar to the Syr River (Jaxartes, in Ancient Greek).
