The Department of Earth Science at the College of Science has witnessed the discussion of a master’s thesis entitled “Hydrochemical Qualities in the Tigris River and the Identification of Melting Loads between Baghdad and Amarah” that was submitted by the student Hala Mohammed al-Siqar and supervised by Dr. Moataz Abdul Sattar al-Dabbas.
The research aimed to study the elements of climate and the temporal changes taking place in the cities of Baghdad, Kut, Ali Al Gharbi Village, Amarah, through the evaluation of hydrochemical and biological elements of the Tigris and the source of pollutants with an identification of dissolved loads transported along the river, finding the relationship between discharge and dissolved loads, and evaluating its validity for drinking and its suitability for other purposes. The results of the study proved that the annual rainfall values of all sites decreased over time, while temperatures and evaporation are constantly increasing, with low discharge rates towards the south of the study area, as a result of climate changes and a decrease in the amount of water emitted by dams to feed the river in the duration of low levels, with a high percentage of total dissolved salts and pollutants, and that the water of Tigris is not suitable for drinking or industry in the study area but is suitable for agriculture, construction and livestock.
