Four stations at twelve sites were selected on Tigris river from Aziziah to the center of Kut city, for a distance more than 90 km. The sites were in a cross -section from both river sides and in the middle. The physical and chemical characterization were studied over the period from June 20l6 to May 2017. Air and water temperatures were varied (11-49) oC and (12-34) oC respectively. Salinity values were (0.410 -0.726) PPT. pH values, conductivity, total dissolved salts and Sulphate were (6.7-8.3), (670 - 1170), (330 -590) and (116.5-242) respectively. Water turbidity was (5.12) and (53) NTU at stations 2 and 1 respectively. Dissolved Oxygen values were low during Summer and high for the other months of the year. BOD values were high during summer.
Total hardness was (650-1190) mg/L. Nutritive values of phosphate was low in March for all stations, while values of Nitrite and Silica were low in June compared with other months. Total alkalinity and chloride were (l14-162) and (74.5-144.9) mg/L respectively.
Results discussion based on the changes of the four stations and the effect of the river sites on the river water. The stations represent the city centres were the river pass through, depending on the population nature and agricultural area and their effect on the water quality and usages.
