The Tigris ( // ) is the eastern of the two great rivers that define Mesopotamia, the other being the Euphrates. The river flows south from the mountains of the Armenian Highlands through the Syrian and Arabian Deserts, and empties into the Persian Gulf.
The Tigris is 1,750 km long, rising in the Taurus Mountains of eastern Turkey about 25 km southeast of the city of Elazig and about 30 km from the headwaters of the Euphrates. The river then flows for 400 km through Southeastern Turkey before becoming part of the Syria-Turkey border. This stretch of 44 km is the only part of the river that is located in Syria. Some of its affluences are Garzan, Anbarçayi, Batman, and the Great and the Little Zab.
Close to its confluence with the Euphrates, the Tigris splits into several channels. First, the artificial Shatt al-Hayy branches off, to join the Euphrates near Nasiriyah. Second, the Shatt al-Muminah and Majar al-Kabir branch off to feed the Central Marshes. Further downstream, two other distributary channels branch off (the Al-Musharrah and Al-Kahla), to feed the Hawizeh Marshes. The main channel continues southwards and is joined by the Al-Kassarah, which drains the Hawizeh Marshes. Finally, the Tigris joins the Euphrates near al-Qurnah to form the Shatt-al-Arab. According to Pliny and other ancient historians, the Euphrates originally had its outlet into the sea separate from that of the Tigris.
Baghdad, the capital of Iraq, stands on the banks of the Tigris. The port city of Basra straddles the Shatt al-Arab. In ancient times, many of the great cities of Mesopotamia stood on or near the Tigris, drawing water from it to irrigate the civilization of the Sumerians. Notable Tigris-side cities included Nineveh, Ctesiphon, and Seleucia, while the city of Lagash was irrigated by the Tigris via a canal dug around 2900 B.C.
The Tigris has long been an important transport route in a largely desert country. Shallow-draft vessels can go as far as Baghdad, but rafts are needed for transport upstream to Mosul.
General Francis Rawdon Chesney hauled two steamers overland through Syria in 1836 to explore the possibility of an overland and river route to India. One steamer, the Tigris, was wrecked in a storm which sank and killed twenty. Chesney proved the river navigable to powered craft. In 1855, a convoy of rafts carrying antiquities from Victor Place's expedition to Khorsabad, Rawlinson's to Kuyunjik and Fresnel's to Babylon was sunk by local tribes near Al-Qurnah.Later, the Euphrates and Tigris Steam Navigation Company was established in 1861 by the Lynch Brothers trading company, who had two steamers in service. By 1908 ten steamers were on the river. Tourists boarded steam yachts to venture inland as this was the first age of archaeological tourism, and the sites of Ur and Ctesiphon became popular with European travellers.
In the First World War, during the British conquest of Ottoman Mesopotamia, Indian and Thames River paddlers were used to supply General Charles Townsend's army, in the Siege of Kut and the Fall of Baghdad (1917).The Tigris Flotilla included vessels Clio, Espiegle, Lawrence, Odin, armed tug Comet, armed launches Lewis Pelly, Miner, Shaitan, Sumana, and sternwheelers Muzaffari/Muzaffar. These were joined by Royal Navy Fly-class gunboats Butterfly, Cranefly, Dragonfly, Mayfly, Sawfly, Snakefly, and Mantis, Moth, and Tarantula.
After the war, river trade declined in importance during the 20th century as the Basra-Baghdad-Mosul railway, a previously unfinished portion of the Baghdad Railway, was completed and roads took over much of the freight traffic.
The Ancient Greek form Tigris (Τίγρις) meaning "tiger" (if treated as Greek) was adapted from Old Persian Tigrā, itself from Elamite Tigra, itself from Sumerian Idigna.
The original Sumerian Idigna or Idigina was probably from *id (i)gina "running water",which can be interpreted as "the swift river", contrasted to its neighbour, the Euphrates, whose leisurely pace caused it to deposit more silt and build up a higher bed than the Tigris. The Sumerian form was borrowed into Akkadian as Idiqlat, and from there into the other Semitic languages (cf. Hebrew Ḥîddeqel, Syriac Deqlaṯ, Arabic Dijlah).
Another name for the Tigris used in Middle Persian was Arvand Rud, literally "swift river". Today, however, Arvand Rud (New Persian: اروند رود) refers to the confluence of the Euphrates and Tigris rivers (known in Arabic as the Shatt al-Arab). In Kurdish, it is also known as Ava Mezin, "the Great Water".

The Tigris is heavily dammed in Iraq and Turkey to provide water for irrigating the arid and semi-desert regions bordering the river valley. Damming has also been important for averting floods in Iraq, to which the Tigris has historically been notoriously prone following April melting of snow in the Turkish mountains.
Recent Turkish damming of the river has been the subject of some controversy, for both its environmental effects within Turkey and its potential to reduce the flow of water downstream. Mosul Dam is the largest dam in Iraq.
Water from both rivers is used as a means of pressure during conflicts.
In 2014 a major breakthrough in developing consensus between multiple stakeholder representatives of Iraq and Turkey on a Plan of Action for promoting exchange and calibration of data and standards pertaining to Tigris river flows was achieved. The consensus which is referred to as the "Geneva Consensus On Tigris River" was reached at a meeting organized in Geneva by the think tank Strategic Foresight Group.
In February 2016, the United States Embassy in Iraq as well as the Prime Minister of Iraq Haider al-Abadi issued warnings that Mosul Dam could collapse.The United States warned people to evacuate the floodplain of the Tigris because between 500,000 and 1.5 million people were at risk of drowning due to flash flood if the dam collapses, and that the major Iraqi cities of Mosul, Tikrit, Samarra, and Baghdad were at risk.
In Sumerian mythology, the Tigris was created by the god Enki, who filled the river with flowing water.
In Hittite and Hurrian mythology, Aranzah (or Aranzahas in the Hittite nominative form) is the Hurrian name of the Tigris River, which was divinized. He was the son of Kumarbi and the brother of Teshub and Tašmišu, one of the three gods spat out of Kumarbi's mouth onto Mount Kanzuras. Later he colluded with Anu and the Teshub to destroy Kumarbi (The Kumarbi Cycle).
The Tigris appears twice in the Old Testament. First, in the Book of Genesis, it is the third of the four rivers branching off the river issuing out of the Garden of Eden.The second mention is in the Book of Daniel, wherein Daniel states he received one of his visions "when I was by that great river the Tigris".
The Tigris River is also mentioned in Islam.[ citation needed ] The tomb of Imam Ahmad Bin Hanbal and Syed Abdul Razzaq Jilani is in Baghdad and the flow of Tigris restricts the number of visitors.
The river featured on the coat of arms of Iraq from 1932–1959.

The Euphrates is the longest and one of the most historically important rivers of Western Asia. Together with the Tigris, it is one of the two defining rivers of Mesopotamia. Originating in the Armenian Highlands of eastern Turkey, the Euphrates flows through Syria and Iraq to join the Tigris in the Shatt al-Arab, which empties into the Persian Gulf.
The geography of Iraq is diverse and falls into five main regions: the desert, Upper Mesopotamia, the northern highlands of Iraq, Lower Mesopotamia, and the alluvial plain extending from around Tikrit to the Persian Gulf.
Transport in Iraq consists of railways, highways, waterways, pipelines, ports and harbors, marines and airports.
The geography of Mesopotamia, encompassing its ethnology and history, centered on the two great rivers, the Tigris and Euphrates. While the southern is flat and marshy, the near approach of the two rivers to one another, at a spot where the undulating plateau of the north sinks suddenly into the Babylonian alluvium, tends to separate them still more completely. In the earliest recorded times, the northern portion was included in Mesopotamia; it was marked off as Assyria after the rise of the Assyrian monarchy. Apart from Assur, the original capital of Assyria, the chief cities of the country, Nineveh, Kalaḫ and Arbela, were all on the east bank of the Tigris. The reason was its abundant supply of water, whereas the great plain on the western side had to depend on streams flowing into the Euphrates.
The Shatt al-Arab, Locally known as Dijla Al-Awara, also known as Arvand Rud in Iran, is a river of some 200 km (120 mi) in length formed by the confluence of the Euphrates and the Tigris in the town of al-Qurnah in the Basra Governorate of southern Iraq. The southern end of the river constitutes the border between Iraq and Iran down to the mouth of the river where it discharges into the Persian Gulf. The Shatt al-Arab varies in width from about 232 metres (761 ft) at Basra to 800 metres (2,600 ft) at its mouth. It is thought that the waterway formed relatively recently in geologic time, with the Tigris and Euphrates originally emptying into the Persian Gulf via a channel further to the west.
The Tigris–Euphrates river system is a large river system in Western Asia which discharges into the Persian Gulf. Its principal rivers are the Tigris and Euphrates along with smaller tributaries.
Mesopotamian Arabic, also known as Iraqi Arabic, is a continuum of mutually-intelligible varieties of Arabic native to the Mesopotamian basin of Iraq as well as spanning into Syria, Iran, southeastern Turkey, and spoken in Iraqi diaspora communities.
Upper Mesopotamia is the name used for the uplands and great outwash plain of northwestern Iraq, northeastern Syria and southeastern Turkey, in the northern Middle East. Since the early Muslim conquests of the mid-7th century, the region has been known by the traditional Arabic name of al-Jazira and the Syriac variant Gāzartā or Gozarto (ܓܙܪܬܐ). The Euphrates and Tigris rivers transform Mesopotamia into almost an island, as they are joined together at the Shatt al-Arab in the Basra Governorate of Iraq, and their sources in eastern Turkey are in close proximity.
The Karun is Iran's most effluent and only navigable river. It is 950 km (590 mi) long. It rises in the Zard Kuh mountains of the Bakhtiari district in the Zagros Range, receiving many tributaries, such as the Dez and the Kuhrang, before passing through the capital of the Khuzestan Province of Iran, the city of Ahvaz before emptying to its mouth into Arvand Rud.
The Mesopotamian campaign was a campaign in the Middle Eastern theatre of World War I fought between the Allies represented by the British Empire, troops from Britain, Australia and the vast majority from British India, against the Central Powers, mostly from the Ottoman Empire.
The Mesopotamian Marshes, also known as the Iraqi Marshes, are a wetland area located in Southern Iraq and Southwestern Iran. Historically the marshlands, mainly composed of the separate but adjacent Central, Hawizeh and Hammar Marshes, used to be the largest wetland ecosystem of Western Eurasia. It is a rare aquatic landscape in the desert, providing habitat for the Marsh Arabs and important populations of wildlife. Draining of portions of the marshes began in the 1950s and continued through the 1970s to reclaim land for agriculture and oil exploration. However, in the late 1980s and 1990s, during the presidency of Saddam Hussein, this work was expanded and accelerated to evict Shia Muslims from the marshes. Before 2003, the marshes were drained to 10% of their original size. After the fall of Hussein's regime in 2003, the marshes have partially recovered but drought along with upstream dam construction and operation in Turkey, Syria and Iran have hindered the process. Since 2016 the Mesopotamian marshes have been listed as an UNESCO Heritage Site.
Al-Qurnah is a town in southern Iraq about 74 km northwest of Basra, that lies within the conglomeration of Nahairat. Qurna is located at the confluence point of the Tigris and Euphrates rivers to form the Shatt al-Arab waterway. Local folklore holds Qurnah to have been the original site of biblical paradise, the Garden of Eden and location of the Tree of Knowledge.
The draining of the Mesopotamian Marshes occurred in Iraq and to a smaller degree in Iran between the 1950s and 1990s to clear large areas of the marshes in the Tigris-Euphrates river system. Formerly covering an area of around 20,000 km2 (7,700 sq mi), the main sub-marshes, the Hawizeh, Central, and Hammar marshes and all three were drained at different times for different reasons.
The Hawizeh Marshes are a complex of marshes that straddle the Iraq and Iran border. The marshes are fed by two branches of the Tigris River in Iraq and Karkheh River in Iran. The Hawizeh marsh is critical to the survival of the Central and Hammar marshes, which also make up the Mesopotamian Marshes, because they are a refuge for species that may recolonize or reproduce in the other marshlands. The Hawizeh Marshes are drained by the Al-Kassarah. This river plays a critical role in maintaining the marshes as a flow-through system and preventing it from becoming a closed saline basin.
The Bahmanshir channel is a secondary estuary of the Karun River that parallels the Shatt al-Arab/Arvand Rud waterway on the far side of the Abadan Island for 70 miles before emptying into the Persian Gulf.
Water supply and sanitation in Iraq is characterized by poor water and service quality. Three decades of war, combined with limited environmental awareness, have destroyed Iraq's water resources management system. Thus, Iraq faces difficulties to realize the target of 91% of households using safe drinking water supply by 2015. Currently, 16% of households report daily problems with supply and 20% use an unsafe drinking water source. Furthermore, animal waste and septic tanks pollute the drinking water network.(11)
