Euphrates and Tigris Rivers are the longest
two rivers in southwest Asia. The Basins of these rivers cover an area of 917
103 km2 which is occupied by about 46 million inhabitants. Four countries
(Turkey, Iran, Iraq and Syria) share the basin area of the Tigris River and the
other four (Turkey, Syria, Iraq and Saudi Arabia) share the catchment area of
the Euphrates River. The flow of the two rivers is decreasing with time due to
construction of dams in the upstream part of the basins and climate change.
This has impacted the water quality of the two rivers. Iraq is highly affected followed
by Syria. The salinity of Tigris Rivers has become alarming downstream Baghdad
while the Euphrates water quality deteriorates before entering the Iraqi
border. To overcome water quality deterioration, international, regional and
national cooperation is required to reach prudent planning for water resources
management of the two basins.
