Chemical and physical properties of the water of the AL-Dijila River within the Kut City

الملخص

Abstract:

A study was conducted on AL-Dijila River within the boundaries of Al-Kut city for a period of 10 months. Eight sites (sections) were selected along the river, starting from  AL-Dijila regulator, with a distance of 1000 meters between each site. The longitudinal section of the river was divided into 8 vertical sections along the river channel, starting from the gates of  AL-Dijila regulator 300 meters from its source.Water samples were collected from the river starting from July 2022 until April 2023 for conducting physical and chemical analyses of the river water. The results of this study are as follows:Turbidity values for AL-Dijila River water for the studied sections ranged from 7.6 to 12.2 NTU. The highest turbidity level recorded was 12.4. NTU in April 2023, while the lowest was 8.9 NTU in July 2022.Temperature values (T) in AL-Dijila River water samples for the studied sections ranged between 11.97 to 25.67°C.Electrical conductivity values in AL-Dijila River water for the studied sections ranged from 0.84 to 1.06 ds.m⁻¹.pH values in AL-Dijila River water for the studied sections ranged from 7.52 to 7.79.Total hardness (TH) values in AL-Dijila River water for the studied sections ranged from 195.77 to 268.25 mg.L⁻¹.Total dissolved solids (TDS) values in AL-Dijila River water for the studied sections ranged from 539.73 to 676.27 mg.L⁻¹.Dissolved cations in Dijila river water samples varied for calcium, magnesium, sodium, and potassium, respectively, with concentrations between 41.6–76.8, 20.88–65.28, 54.74–91.31, and 2.34–4.29 mg.L⁻¹. Dissolved anions in Dijila river water samples ranged between 82.72 – 236.79 , 31.2 – 75 , 158.4 -207.36 MG. L-1 for chloride bicarbonate and sulfate, respectively.
