تقييم المخاطر البيئية الناجمة عن ارتفاع تراكيز الاملاح في مياه نهر الديوانية و اثرها على صلاحية الاستخدام

الملخص EN

The research dealt with the environmental impact of the high concentrations of salts in Al-Diwaniyah River within Al-Qadisiyah Governorate and the variation of its effects between the locations of the research samples, whose geographical locations were confined from the north of the Sunni area to the south of the city of Hamza, including a study of (10) sites and for the winter and summer seasons, which were embodied in the months of January and July for the year 2021 AD.

In the light of the study of natural and human factors, it became clear that there is a correlation between the effect of climatic factors represented by the factor of heat and drought, as well as the great role of human factors in terms of the impact of the political factor on the decrease in water discharge of the Euphrates River, which in turn affects the decrease in the recharge of the waters of Al-Diwaniyah River, which is one of its branches.

The human activities represented by direct drainage of wastewater and sewage water to the Al-Diwaniyah River also had a direct effect on the high concentrations of salts and their variation between the research areas.

This became clear in the light of comparing it with the Iraqi environmental standards and determinants issued by the Ministry of Environment, and the characteristics of the Diwaniyah River water were also compared with the standards applied in American research laboratories.

Suitable for watering plants that can withstand high salinity and in soils with good drainage of sewage water.

It is also not suitable for raising fish in river basins that cannot withstand high salinity.
