Euphrates

The Euphrates is a major river that originates in the mountains of eastern Turkey, then flows through Syria and Iraq. It is the longest river in Western Asia; its length is estimated at approximately 2,800 kilometers, although reported figures vary depending on how the source and upper course are measured.

The Euphrates and Tigris are the two rivers that created the Mesopotamian plain. They meet at a location called Al-Qurnah in southern Iraq, where they form the Shatt al-Arab, which eventually flows into the Persian Gulf. Some of the Euphrates water also reaches the marshes and wetlands of southern Iraq.

Source and tributaries

The source of the Euphrates consists of two small rivers emerging from the high plateau of eastern Anatolia: the Karasu and the Murat. These join within Turkey, then the river flows southeastward, entering Syria and crossing the plain region in the north of the country, finally entering Iraq where it runs through the western part of the country. Most of the Euphrates water originates from snow and rain in the Turkish mountains, which causes water levels to rise during summer as the snow melts.

History and ancient cities

Some of the earliest cities in recorded history, such as Uruk, Ur, Babylon, and Mari, emerged in the Euphrates region. The irrigation systems dependent on the river's waters were the foundation for Mesopotamian systems of governance, cuneiform writing, and early law. The river also played an important role in defining the boundaries of ancient kingdoms, for a long time serving as a dividing line between eastern and western powers.

Dams and water management

In the twentieth and twenty-first centuries, the three countries through which the river flows have constructed large dams for electricity generation and irrigation. Turkey built a major development program known as GAP, which includes the Keban and Atatürk dams. Syria built the Tabqa dam, which created Lake Assad, while Iraq has dams such as Haditha. These structures have altered the flow of water throughout the seasons.

Water disputes and regional challenges

There is no comprehensive agreement between the three countries regarding the division of Euphrates water, leading to recurring negotiations and disputes. Iraq and Syria argue that the dams upstream have reduced the volume of water reaching their territory. Also documented are decreased water flow, the drying up of agricultural land in southern Iraq, and recurring droughts linked to climate change.
