| Abstract | ||
| To know water quality for multi uses in the north of Hilla city, it is important to study the quality of the water parallel with the quantity. In this research, two national methods are adopted to evaluate and judge the suitability of Euphrates River in this zone (study case) for irrigation use. These methods are the water quality index (WQI) of the Canadian and Bhargava model. The main river passing through the north of Hilla city is Euphrates River and his branch Hilla River, the uses of its water are different and its use for irrigation depends on many environmental parameters. The researcher studied the quality of this river for irrigation use during 2011. Took four stations on the river in Babylon (Euphrates River/AL-Musiab, Euphrates River/Kifil, Hilla River/ Hindia barrage and Hilla river/Hilla. The main results showed that there is no difference between the two techniques at significance level (0.08) and the quality of the river inter the boarder classified as GOOD and FAIR according to Bhargava and the Canadian method respectively. Also that there is a serious deterioration in the water quality downstream Al-Kifil station because of the local drains that discharge in the river. These results ensure the need to receive higher water quality at the boarders (quantity and quality) to raise the quality in the downstream the river. | ||
