• Abstract

  Iraq relies in its water resources on the water of the Tigris and Euphrates Rivers and their tributaries. The long-term average annual flow of the Euphrates River was 30 BCM while it is 21.2 BCM for the River Tigris. The tributaries of the Tigris River contribute about 24.78 BCM and in addition, there are side valleys from the eastern border that contributes at least 7 BCM. The flow of these rivers decreased for since the seventies due to the hydrological projects built in riparian countries and climate change. Now, the discharge of the Tigris River and its tributaries at Baghdad is about 16 BCM while it is about 4.4 BCM in the Euphrates.
