Research indicates that the salinity of the Euphrates water in Iraq has increased considerably since the nearly simultaneous construction of the Keban Dam in Turkey and the Tabqa Dam in Syria. This increase can, among other things, be related to the lower discharge of the Euphrates as a result of the construction of the Keban Dam and the dams of the Southeastern Anatolia Project (GAP) in Turkey, and to a lesser degree of the Tabqa Dam in Syria. High-salinity water is less useful for domestic and irrigation purposes.
