Some of the physical and chemical properties of Al-Khosur river water were studied in the city of Mosul. Samples were collected seasonally from 6 sites distributed along the banks of the river and at a rate of 3 replicates per site. Samples were collected and then taken to the laboratory and tests were carried out. Tests included the temperature, pH, electrical conductivity were measured in the site. Turbidity, total alkalinity, chloride, sulfates and phosphates were measured in the Laboratory. The results of the study showed that the temperature values ranged between (10.23-25.86) Co and pH value ranged between (7.12-8.13), while the value of electrical conductivity ranged between (844-2425) µs/cm and the turbidity was with values ranging between (31.73-87.40) NTu. As for the values of total alkalinity, sulfates, chloride and phosphates, their ranges were (126.0-228.7), (74.1-147.8), (61.83-126.27) and (0.15-1.98) mg/l respectively. The variations in the values of water characteristics were due to the differences in locations and the human activities through the river
