West Asia’s longest river still feeds Mesopotamia’s name
At about 2,780 kilometres the Euphrates is West Asia’s longest river and Asia’s fifteenth longest, draining some 440,000 square kilometres across six countries. Paired with the Tigris it defines Mesopotamia, the land between the rivers, yet Iraqi officials warned in 2021 that it could run dry by 2040.
It forms where Turkey’s Kara Su (about 450 km) and Murat Su (about 650 km) meet ten kilometres above Keban. Both rise northwest of Lake Van, at 3,290 and 3,520 metres, and by Keban Dam the joined river has fallen to 693 metres. Their catchments cover 22,000 and 40,000 square kilometres, while estimates for the whole basin vary widely, from as little as 233,000. In Syria the Sajur, Balikh, and Khabur add modest flows from the Taurus foothills.
Most water arrives as rain and snowmelt; April and May bring roughly 36 percent of yearly discharge by one estimate, 60 to 70 percent by others. Dams built since the 1970s and heavier irrigation withdrawals have reshaped that pattern, as figures gathered after 1990 show, and in 2021 Iraq’s water ministry blamed climate change and drought for the risk of the river failing by 2040.
Greek Euphrátēs traces through Old Persian and Elamite to Sumerian Buranuna and Akkadian Purattu, names on third-millennium tablets from Shuruppak and Nippur. Armenian Yeprat, Hebrew Perat, Turkish Fırat, and Mandaic Praš keep the root alive; Mandaean scriptures such as the Ginza Rabba honour it as Praš Ziwa.
Rainfall drops steadily downstream, so the river passes from woodland-steppe into open steppe between Raqqa and the Iraqi border, where white wormwood grows on long-overgrazed land. Of 52 fish species in the Tigris–Euphrates basin, 34 are carps and their kin; the British nicknamed one, the mangar, the Tigris salmon. Neo-Assyrian reliefs show lion and bull hunts here, and travellers into the nineteenth century described wildlife now rare or gone. The desert poplar, Populus euphratica, bears the river’s name.
