WThe 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.
WThe 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.
WThe Central or Qurna Marshes are a large complex of wetlands in Iraq that, along with the Hawizeh and Hammar marshes, make up the Mesopotamian Marshes of the Tigris–Euphrates river system. Formerly covering an area of around 3000 square kilometres, they were almost completely drained following the 1991 uprisings in Iraq and have in recent years been reflooded.
WThe Glory River , Glory Canal or Prosperity Canal is a shallow canal in Iraq about two kilometers wide built by Saddam Hussein in 1993 to redirect water flowing from the Tigris river into the Euphrates, near their confluence at the Shatt al-Arab. It helped cause an environmental and humanitarian disaster since it diverted natural water flow from the Central Marshes and effectively converted much of the wetlands into a desert.
WThe Hammar Marshes are a large wetland complex in southeastern Iraq that are part of the Mesopotamian Marshes in the Tigris–Euphrates river system. Historically, the Hammar Marshes extended up to 4,500 km2 (1,700 sq mi) during seasonal floods. They were destroyed during the 1990s by large-scale drainage, dam and dike construction projects. Since 2003, they are recovering following reflooding and destruction of dams.
WThe 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.
WThe Hevsel Gardens, are the seven hundred hectares of cultivated, fertile lands near the Tigris in eastern Turkey, between the Diyarbakır Fortress and the river. The fortified city was enclosed by a two-part system of defensive walls, and the gardens, fed by springs on the steep slope below, played a vital role in keeping the city provisioned and watered. The gardens were added to the UNESCO tentative list in 2013, and they became a World Heritage Site in 2015, along with the walls of Diyarbakır Fortress.
WThe Kut Barrage is a barrage on the Tigris river, located in the modern town of Kut in Wasit Governorate, Iraq. It is 516 metres (1,693 ft) long, 10.5 metres (34 ft) high and consists of 56 gates, each 6 metres (20 ft) wide. The maximum discharge of the barrage is 6,000 cubic metres (7,800 cu yd), but actual discharge has not exceeded 2,000 cubic metres (2,600 cu yd) in the last 10 years. The barrage supports a road and includes a lock for boats passing up and down the Tigris. Its purpose is to maintain a sufficiently high water level in the Tigris to provide water for the Gharraf irrigation canal, which branches off the Tigris just upstream from the Kut Barrage. Before the construction of the Kut Barrage, the Gharraf canal only received water during periods of flood in the Tigris. The water level in the canal is maintained by the Gharraf Head Regulator, which was constructed at the same time as the Kut Barrage.
WQanus Island is an Islamic State of Iraq and Syria staging area located in the Tigris River in Salah Ad Din Province, Northern Iraq. It was bombed on 10 September 2019 during the Iraqi insurgency. American F-15 and F-35 fighter jets dropped 40 tonnes of explosives by the US-led coalition forces.
WThe so-called Tigris tunnel is a cave approximately 50 miles north of Diyarbakır in Turkey. It has a length of about 750 m (2,461 ft). The Berkilin Cay flows through this cave. It forms a source of the Tigris, but not the main one, although the exit was long believed to be this. In fact the spring is near Bingöl not far away from the Tigris tunnel. In its vicinity there are several archaeological monuments, three Assyrian Empire and Neo-Assyrian rock reliefs and five inscriptions.
