River in Southwest Asia, formed by the confluence of the Euphrates and the Tigris in the town of al-Qurnah in the Basra Governorate of southern Iraq
At the mouth it carries 1,500 m³/s on average: an Olympic pool every 1.7 seconds. Its basin covers 884,000 km², about the size of VE. 55.4 million people live in it. Highest water: from January to March; lowest: from July to October. It is heavily dammed: reservoirs can hold 245% of a year's flow.

Shatt al-Arab, month by month
Highest water: from January to March
Lowest water: from July to October. Best months to visit: from February to April and from November to December.
From about 380 m³/s in the lowest month to 7,600 m³/s in the highest. An estimate: the monthly flow is modelled from the lowest and highest months of WaterGAP (RiverATLAS, 1971–2000) and the rain and snow along the river (WorldClim). Dams change the real rhythm. The chip is the average air temperature; below it, the month's rain.
