Online published on 21 February, 2019. Abstract Background This study was conducted to assess the effects of Diyala River on physical-chemical characteristics and total account of coliform bacteria of Tigris River in Baghdad city by (NFS-WQI). Aim To assess the effect of the Diyala River upon the water quality of Tigris River of Baghdad. Materials and Method Water samples were taken bimonthly at four stations, first on as control station and second one at the point in which Diyala River joint with Tigris River and nine parameters (viz. water, temperature, turbidity, dissolved oxygen, BOD, pH, TS, NO3, total PO4 and total coliform bacteria) were analyzed. According to NSF-WQI, Results Tigris river had fluctuated between medium at station 1 and bad water quality at stations 2, 3 and the refluxes to medium characteristics at station4 after 5.5 Km from a jointed point between Diyala and Tigris river as well as increasing in turbidity, NO3, PO4 concentration, BOD and decreasing of DO. Conclusion The model gave a good idea to assessing the water quality of Tigris River at Baghdad region under the effect of dryness and large quantities of pollutants on it.
