Abstract

The Stream Quality Model (QUAL2KW) used for simulation the Quality of Euphrates River Water. The study area extends along (78 km) of the river path from downstream of Ramadi Barrage to upstream of Falluja Barrage. Tharthar-Euphrates Canal carries the dead storage water from Tharthar reservoir to the Euphrates River at the meet point (52 km) from downstream of Ramadi Barrage. Statistical tests conducted between values of water quality parameter concentrations obtained from sites with the values simulated by this model. The results of statistical tests showed great convergence and gave reliability and credibility in adopting the use of this model for river quality simulation. To evaluate the effect of using the reservoir dead storage water on the river water quality, model operated with scenarios represented different releases of dead storage water by (30%, 60%, and 100%) lead to increases in these quality parameters concentration by (3%-9%), (5%-14%) and (8%-19%) respectively, which does not significantly affect the Euphrates River’s water quality. The results of applying the various scenarios showed that 30% is optimal for maintaining the quality of river’s water for drinking purposes after performing the required treatments, and 100% for maintaining the quality of river’s water for irrigation purposes without affecting the various plants
