【 摘 要 】

In Bahar County (Iran), rivers are among the important sources of water for the agricultural sector. Therefore, this research evaluated the parameters of temperature, pH, Total Dissolved Solids (TDS), turbidity, nitrate, total phosphate, dissolved oxygen (DO), Biological Oxygen Demand (BOD5), and fecal coliform at five stations for five months (from February 2015 to June 2015) to determine water quality in the rivers. Based on this evaluation, the NSFWQI index was calculated and, finally, the routes of the rivers were zoned. The best water quality was recorded at Station Number 3 with the NSFWQI Value of 80 in January, and the worst at Station Number 5 (latgah) with the NSFWQI Value of 37 in June. Based on the mean NSFWQI indices, water quality was Medium at Stations Number 1, 2, and 4, good at Station Number 3, and bad at Station number 5.
