Orontes River is one of the most important rivers in Syria and a major source of water for drinking, irrigating, and industrial purposes. This research aims to study the effect of temporal and spatial changes on the water quality of the Orontes River and to assess its suitability for different uses. Seasonal water quality monitoring data for the period between 2010 and 2020 consisting of 21 quality parameters (EC, COD, BOD, TUR, DO, pH, NH4, Cl, Na, T, TSS, TDS, SS, FC, NO3-, PO4-3, K, Ca, Mg, SAR, TH) at 11 stations along the river basin were used. The data were analyzed using statistical analysis techniques to study the correlation between these indicators and to determine the least number of variables that affect water quality. MANOVA analysis was applied to the dataset to study the linear relationship between independent variables (seasons and stations) and dependent variables (quality parameters). The results showed that 9 and 14 water quality parameters were influenced by seasonal and spatial changes, respectively. Additionally, the combined effect of seasonal and spatial changes influenced EC, DO, COD, PO4-3, NO3-. Therefore, these water parameters can be considered useful in determining pollution severity and evaluating water management policies in the studied area.
