Total nitrogen (TN) and total phosphorus (TP) levels in water and sediments of the Tigris River were analyzed at 7 different sites during the period of February 2008 to January 2009. Cluster analysis, analysis of variance (ANOVA) and correlation analysis were performed to explore temporal and spatial variations of TN and TP in the river. The results revealed that TN and TP concentrations of water and sediments in the wet season were higher than those in the dry season. According to trophic state classification, the river was classified as eutrophic based on both mean and median concentrations of TN and TP. Cluster analysis indicated that TN and TP concentrations in water column were higher in the urban areas. TP concentrations in sediment were found higher at sites receiving agricultural runoff and mine wastewater discharge, while TN concentrations were found higher at sites receiving untreated domestic wastewater. TN and TP concentrations in sediments at all sites were below the SEL (severe effect levels)
