الملخص EN

There is a water shortage problem in Euphrates river , beside the water quality problem of river water , since the salinity is higher than its average .

In this study attempt to relate between the problem of water quality and the river discharge decrease in addition to the effect of using the storage water in the lakes of dams on the water quality .

Samples of water from two different stations along Kufa river were tested and analysis monthly for three years ( 2007 to 2009 ) .

Five variables were analysis for total dissolved solids ( TDS ) , electrical conductivity ( Ec ) , sodium ( Na ) , calcium ( Ca ) and magnesium ( Mg ) .

Results shows that decreasing the river discharge and uses of lake water causes to increasing the salinity of water about ( 82% ) .

While there is no effect of the sodium hazard .

The quality of water for Kufa river for irrigational uses was ranging between high to medium salinity and it can be conceder is permissible water , and it is safe water as sodicity hazard .
