An ecological assessment for interactions between the physico-chemical characteristics of Gharaf river characteristics, Southern Iraq
Journal Title: Journal of Research in Ecology - Year 2018, Vol 6, Issue 2
Abstract
This study was based on samples taken from one of the main branches of the Tigris River; Gharraf river, at Kut barrage in Wasit Province, Iraq. Which was aimed to study the physical and chemical properties of water. Monthly samples were collected randomly from the water, for 12 months, from January till December 2016. During the collection process; 5 stations on the river were chosen for sampling with ±10 km distance between each of the stations, including Wasit Province. The results showed that water temperature was affected by the air temperature, the temperature was from 13.3 to 30.6°C. However, the pH values were weak alkaline, the readings were 7.1-9.8. In addition, both of the dissolved oxygen and percentage oxygen saturation values were under the critical point in some of the reading at river Gharaf marking as low as 4.0-13.0 mg/L and 44.49-127.52% for the DO and POS, respectively. As for BOD5 values the results were from 0.4-6.8 mg/L, that made this rivers cleanness doubtful. As for the turbidity, it was observed that the water was turbid when the values were from 4.2-101.0 NTU. Turning now to total alkalinity, the results were from 183.0-384.0 mg/L. The results showed that river water is oligohaline, Gharaf results were 480-1070 µ/cm for conductivity and 0.30-0.68 for salinity. TDS and TSS results were 1.0-171.0 mg/L, 10.0-121.0 mg/L, respectively. Gharaf are considered to have hard water, as having hardness values from 312- 580 mg/L. As for anion and cation the results as follows: Bicarbonates 62-185 mg/L, Ca+2 76.15-160.32 mg/L, Mg+2 2.29-68.15 mg/L, sulphate 50-240 mg/L, nitrates 0.001-2.85 mg/L and phosphates 0.019-0.39 mg/L
