Water‐related hazards, such as drought, floods, erosion, and various kinds of pollution, should be factored into any integrated approach to water‐resource management. This research attempt has been made to assess the process of water pollution in the Dareh Morad Beik (DMB) River, whose length is about 18 km and whose average flow rate is 250 L/s. The quality of river water, including chemical oxygen demand (COD), biochemical oxygen demand (BOD), dissolved oxygen (DO), nitrate, fecal coliform, and total coliform, were all measured and evaluated at three different sampling stations within different months of the year. The information was gathered by conducting experiments and through field visits, as well as by library study. The results of this research showed that, from a microbiological point of view, the water of the DMB was polluted during the year. Based on the results obtained it was determined that the amount of COD and BOD at station 1 was negligible. Also the influx of qantas waters from Hamadan City into the DMB has caused dilution of COD, BOD, and nitrate of that river at station 3.
