The Aras [a] is a transboundary river in the Caucasus. It rises in eastern Turkey and flows along the borders between Turkey and Armenia, between Turkey and the Nakhchivan exclave of Azerbaijan, between Iran and both Azerbaijan and Armenia, and, finally, through Azerbaijan where it flows into the Kura river as a right tributary. It drains the south side of the Lesser Caucasus Mountains, while the Kura drains the north side of the Lesser Caucasus. The river's total length is 1,072 km (666 mi) and its watershed covers an area of 102,000 km2 (39,000 sq mi). The Aras is one of the longest rivers in the Caucasus.
In classical antiquity, the river was known to the Greeks as Araxes (Greek : Ἀράξης). Its modern Armenian name is Arax or Araks (Armenian : Արաքս). Historically, it was called Eraskh (Old Armenian : Երասխ, Yeraskh in modern pronunciation) by Armenians and its Old Georgian name is Rakhsi (რახსი). In Azerbaijani, the river's name is Araz. In Persian, Kurdish and Turkish its name is ارس (Aras).
The Aras is supported by the Kocagün stream, Dallı stream and Orman stream from the Bingöl Mountains on the borders of Varto district merge with it around the Kırıkhan village of Tekman district. [1] [2] It is surrounded by the Aras Mountains from the south. [3] The Aras meets the Akhuryan River southeast of Digor. From Digor it flows along the Armenia–Turkey border, then runs close to the corridor that connects Turkey to Azerbaijan's Nakhchivan exclave, and continues along the Iranian-Armenian and the Iranian-Azerbaijani border. [4] The Aras is fed by several major tributaries, including the Arpa Çayı (also known as the Akhuryan), which gathers the waters from the Kars River and Lake Çıldır located in Turkey, the Hrazdan River, which empties into Lake Sevan in Armenia, and the Qareh Sū, originating from the Sabalān Mountains in northeastern Iranian Azerbaijan. [5]
The lowest point in Armenia is a point along the Aras at an elevation of 380 metres (1,250 ft). [6]
The following rivers are tributaries of the Aras, from source to mouth: [7] [8] [9]
In Armenian tradition, the river is named after Arast, a great-grandson of the legendary Armenian patriarch Haik. [10] The name was later Hellenized to Araxes and was applied to the Kura–Araxes culture, a prehistoric people who flourished in the valleys of the Kura and Aras. The river is also mentioned in the last chapter of Virgil's Aeneid VIII, as "angry at the bridge," since the Romans built a bridge over it so that it is thereby conquered. The river Aras has been associated with the biblical rivers Gihon and Pishon. [11] Robert H. Hewsen described Aras as the only "true river" of Armenia and as "Mother Araxes," a symbol of pride to the Armenian people. [12]
According to a legend cited by Strabo, in ancient times, the Araxes river in Armenia had no outflow to the Caspian Sea, but spread out in plains and created a lake without outflow. [13]
During Islamic times, the Araxes became known in Arabic parlance as al-Rass (not to be confused with modern-day Ar Rass) and in Perso-Turkish contexts as Aras. [4]
In modern history, the Aras gained significance as a geographic political boundary. Under the terms of the Treaty of Gulistan and the Treaty of Turkmenchay, the river was chosen as the border limit between the Russian Empire and Qajar Iran, as the latter was forced to cede its Caucasian territories to Russia. [14] Because of these 19th-century border changes, one modern, not widely accepted scheme draws Aras River as the line of continental demarcation between Europe and Asia. [15]
In 1963–1970, Iran and the Soviet Union built the Aras Dam near the Azerbaijani city of Nakhchivan, creating the Aras Reservoir. In 1999–2008, Iran built the Khoda Afarin Dam near the historic Khudafarin Bridges, creating the Khoda Afarin Reservoir, and the Giz Galasi Dam 12 km down the river, creating the Giz Galasi Reservoir. Iran and Armenia are planning to build the Meghri Dam near the Armenian town of Meghri. [16]
In 2006, a bird research and education center was established by KuzeyDoğa, a Turkish non-governmental organization for nature conservation, in the Aras Valley at the village Yukarı Çıyrıklı, in the Tuzluca district of Iğdır Province, Turkey. It is one of Turkey's two bird-ringing stations that remain active yearly. [17] Between 2006 and 2021, more than 145,000 birds of 201 species were ringed, and 306 bird species were observed at this station. Sixty-three percent of the 489 bird species found in Turkey are recorded at this wetland, making it eastern Turkey's most species-rich wetland for birds. The number of ringed and observed 306 bird species comprises 90 percent of the 340 bird species in Iğdır Province, the most bird species rich landlocked province of Turkey. Seven new bird species were observed during the bird ringing activities in 2012 alone, including the raptor Shikra, or Little Banded Goshawk (Accipiter badius), which was new to Turkey's avifauna. [18] [19]
A Biology professor at the University of Utah and a president of the KuzeyDoğa Society, Çağan Şekercioğlu, appealed to the Ministry of Forest and Water Management to drop the Tuzluca Dam project, which would destroy the wetland harboring bird wildlife in the Aras Valley. [18] [20] In 2013, the ministry granted the site the highest level of conservation status (Nature Conservation Area).
Azerbaijan is a country in the Caucasus region, situated at the juncture of Eastern Europe and West Asia. Three physical features dominate Azerbaijan: the Caspian Sea, whose shoreline forms a natural boundary to the east; the Greater Caucasus mountain range to the north; and the extensive flatlands at the country's center. About the size of Portugal or the US state of Maine, Azerbaijan has a total land area of approximately 86,600 km2, less than 1% of the land area of the former Soviet Union. Of the three Transcaucasian states, Azerbaijan has the greatest land area. Special administrative subdivisions are the Nakhchivan Autonomous Republic, which is separated from the rest of Azerbaijan by a strip of Armenian territory, and the Nagorno-Karabakh Autonomous Region, entirely within Azerbaijan. The status of Nagorno-Karabakh is disputed by Armenia, but is internationally recognized as territory of Azerbaijan.
The Kura, also known in Georgian as Mtkvari, is an east-flowing transboundary river south of the Greater Caucasus Mountains which drains the southern slopes of the Greater Caucasus east into the Caspian Sea. It also drains the north side of the Lesser Caucasus, while its main tributary, the Aras, drains the south side of those mountains. Starting in northeastern Turkey, the Kura flows through to Georgia, then into Azerbaijan, where it receives the Aras as a right tributary, and finally enters the Caspian Sea. The total length of the river is 1,515 kilometres (941 mi).
The Nakhchivan Autonomous Republic is a landlocked exclave of the Republic of Azerbaijan. The region covers 5,502.75 km2 (2,124.62 sq mi) with a population of 459,600. It is bordered by Armenia to the east and north, Iran to the southwest, and Turkey to the west. It is the sole autonomous republic of Azerbaijan, governed by its own elected legislature.
The Kura–Araxes culture was an archaeological culture that existed from about 4000 BC until about 2000 BC, which has traditionally been regarded as the date of its end; in some locations it may have disappeared as early as 2600 or 2700 BC. The earliest evidence for this culture is found on the Ararat plain; it spread north in the Caucasus by 3000 BC.
The Treaty of Turkmenchay was an agreement between Qajar Iran and the Russian Empire, which concluded the Russo-Persian War (1826–1828). It was second of the series of treaties signed between Qajar Iran and Imperial Russia that forced Persia to cede or recognize Russian influence over the territories that formerly were part of Iran.
Iğdır Province is a province in eastern Turkey, located along the borders with Armenia, Azerbaijan, and Iran. Its adjacent provinces are Kars to the northwest and Ağrı to the west and south. Its area is 3,664 km2, and its population is 203,594 (2022). Its population was 168,634 in 2000 and 142,601 in 1990. The province is considered part of Turkish Kurdistan and has a Kurdish majority with a pretty close Azerbaijani minority.
Sadarak District is one of the 7 districts of the Nakhchivan Autonomous Republic of Azerbaijan. The district borders the district of Sharur, as well as the Iğdır Province of Turkey, Ararat Province of Armenia and the West Azerbaijan Province of Iran. Its capital is Heydarabad and largest settlement is Sadarak. As of 2020, the district had a population of 16,100.
The Lesser Caucasus or Lesser Caucasus Mountains, also called Caucasus Minor, is the second of the two main ranges of the Caucasus Mountains, of length about 600 km (370 mi). The western portion of the Lesser Caucasus overlaps and converges with east Turkey and northwest Iran. It runs parallel to the Greater Caucasus, at a distance averaging about 100 km (62 mi) south from the Likhi Range (Georgia), and limits east Turkey from the north and north-east. It is connected with the Pontic range and separated from it by the Kolkhida Lowland (Georgia) in the west and Kura-Aras Lowland (Azerbaijan) in the east.
Meghri is a town and the centre of the Meghri Municipality of the Syunik Province in southern Armenia, near the border with Iran. As of the 2011 census, the population of the town was 4,580. According to the 2020 official estimate, Meghri's population is around 4,500. Meghri is located 376 km south of the capital Yerevan and 73 km south of the provincial capital Kapan.
The Kura-Aras Lowland, Kura-Aras Depression or Kura-Aras Basin is a vast depression in central-southern Azerbaijan defined by the valleys of the Kura River and Aras River. It is situated by the West shore of the Caspian Sea and is part of the Aral-Caspian Depression. It is delimited by the Greater Caucasus from the North, Lesser Caucasus from the West and the Talysh Mountains from the South. The name is derived from the names of the two rivers in the area: the Kura and the Aras.
Kültəpə is a settlement dating from the Neolithic, a village and municipality in the Babek District of Nakhchivan, Azerbaijan. It has a population of 1,859.
Khoda Afarin Dam is an earth-fill embankment dam on the Aras River straddling the international border between Iran and Azerbaijan. It is located 8 kilometres (5.0 mi) west of Khomarlu in East Azerbaijan Province, Iran and 14 kilometres (8.7 mi) southwest of Soltanlı in Jabrayil District, Azerbaijan. Armenian de facto protectorate Republic of Artsakh occupied the area in 1993, during the First Nagorno-Karabakh War, but on 18 October 2020, the Azerbaijani forces retook control of the dam during the 2020 Nagorno-Karabakh conflict. It is located 1 km (0.62 mi) upstream of the Khudafarin Bridges.
The Azerbaijan–Turkey border is a short 17 km (11 mi) long international border between the Republic of Azerbaijan and the Republic of Turkey. The border is located at the southeastern tip of the Iğdır Province on the Turkish side and at the northwestern tip of the Nakhchivan Autonomous Republic on the Azerbaijani side; running entirely along the Aras river, it is the shortest border for both countries.
The power generation potential of the rivers in Azerbaijan is estimated at 40 billion kilowatt per hour, and feasible potential is 16 billion kilowatt per hour. Small-scale hydro has significant developmental potential in Azerbaijan. In particular, the lower reaches of the Kura river, the Aras river and other rivers flowing into the Caspian Sea. Hydropower could conceivably provide up to 30% of Azerbaijan’s electricity requirements. Currently, hydropower, dominated by large-scale dams, provides 11.4% of Azerbaijan’s electricity.
The Azerbaijan–Iran border is 689 km in length and consists of two non-contiguous sections separated by the Armenia–Iran border.
The Armenia–Iran border is 44 km (27 mi) in length and runs from the tripoint with Azerbaijan’s Nakhchivan region in the west to the tripoint with Azerbaijan proper in the east. The border has been protected by guards of the Russian Federal Security Service since 1992. On 9 May 2024, Russian Presidential spokesman Dmitry Peskov announced that Russian border guards will continue to serve on Armenia's borders with Iran and Turkey, at the request of the Armenian side. On 8 October 2024, Armenian prime minister's spokesperson Nazeli Baghdasaryan announced that the Armenian border guard troops will participate in protecting Armenia's borders with Iran and Turkey, together with the Russian border guard troops, starting from 1 January 2025.
Capoeta kaput is a species of algae eating scrapers discovered in 2019. Known locally as the Blue Aras scraper, this rare species prefers large rivers. It has not been evaluated by the IUCN yet but may need protection. The freshwater fish primarily inhabits rivers of the Araxes basin in Asia, and has been found so far in at least Armenia, Iran and Turkey. C. kaput can be distinguished by several physical markers, such as its nine dorsal branched rays, a larger number of vertebrae than most other species in the genus, and it is about 262 mm (10.3 in) in length. The species has been discovered recently enough that it's been the subject of relatively little research.
The Giz Galasi Reservoir is a reservoir on the Aras River, created by the Giz Galasi Dam straddling the international border between Azerbaijan and Iran. The reservoir has a total capacity of 1.6 billion cubic metres. It is located between Jabrayil and Zangilan districts of Azerbaijan and Khoda Afarin County of Iran. It was formed between 1999 and 2008. The reservoir is located 12 km (7.5 mi) below the Khoda Afarin Reservoir. From 1993 to 18 October 2020, the reservoir was under the control of the Republic of Armenia together with the hydroelectric power station of the same name. It is planned to provide 12,000 hectares of land with water. Parts of the lake have been declared Important Bird Area.
Giz Galasi Dam is an embankment dam on the Aras River straddling the international border between Azerbaijan and Iran. It is located in Jabrayil District, Azerbaijan, and Khoda Afarin County, East Azerbaijan Province, Iran, 12 km (7.5 mi) downstream of the Khoda Afarin Dam. Built both to generate electricity and to irrigate the plains in the region, it is the third joint Azerbaijan–Iran project on the Aras River. The Giz Galasi Reservoir will provide 12,000 hectares of land with water.
