التغيرات النوعية لمياه نهر الفرات بين الناصرية و القرنة و آثارها في التنمية و البيئة

Abstract EN

The waters of the Euphrates River has a great importance for central and southern Iraq because of the dry climate and scarcity of traditional water sources (Rain and surface water and the groundwater) where the region mainly depends on surface water of the Euphrates River due to lack of quantities of falling rainfall which does not exceed (100) mm / year as well as poor groundwater which cannot be relied upon for different uses such as human, agricultural and industrial as well as the investments that placed in the highest basin (in Turkey and Syria).

These causes combined reduced water revenues to the site of Nasiriyah to (2.4) billion m 3 during the water year (2015-2014) compared to the period (1950-1978) which was recorded water revenues (14.4) billion cubic meters.

This was reflected negatively in water quality of Euphrates River down the tub and therefore on water uses in the region.

Therefore, the research aims to identify the chemical changes which occurred on the river by sampling water and analyzed in laboratories of Marine Sciences Center at the University of Basrah and comparing the results for the period (summer 2015) (Winter 2016) with chemical analyzes for the river water for the 1960s of the last century and identify different variables and their sites and find out how suitable the current water for different uses according to the Iraqi and international standards for the quality of potable water as well as for agriculture, industry and the environment.
