Tigris–Euphrates river system Tigris–Euphrates river system The Tigris and Euphrates, with their tributaries, form a major river system in Western Asia. From sources originating in eastern Turkey, they flow by/through Syria through Iraq into the Persian Gulf. The system is part of the Palearctic Tigris–Euphrates ecoregion, which includes Iraq and parts of Turkey, Syria, Iran, Saudi Arabia, Kuwait, and Jordan. From their sources and upper courses in the mountains of eastern Anatolia, the rivers descend through valleys and gorges to the uplands of Syria and northern Iraq and then to the alluvial plain of central Iraq. The rivers flow in a south-easterly direction
Water conflict in the Middle East and North Africa demands may soon exceed Egypt’s. Irrigating only half of Ethiopia’s arable lands would reduce water flow to downstream Sudan and Egypt by 15%. The Tigris-Euphrates River Basin consists of its two primary rivers – The Tigris River and the Euphrates River – and their minor tributaries. Both the Tigris and the Euphrates originate in southeastern Turkey. The Tigris flows from Turkey, tracing the border between Turkey and Syria for 32 km before flowing south through Iraq. From its origin in Turkey, the Euphrates flows into Syria from the north, before continuing on through Iraq. The two rivers meet in Iraq
