| Abstract | ||
| The aim of the present study is to consider Biological Index of the river; for this purpose, limnological and hydrobiological studies of the river were carried out seasonally in 2009. At this study, seven sampling stations were determined based on limnological standard method along the river; afterwards sampling of invertebrates (Biological Index) and water quality (BOD) were performed seasonally during study period. The results showed that first station (Cheshmeh-Ali) is free of pollution while the fourth sampling station (Doab) is the most polluted region at the river because the first station has no pollutant resource but the fourth station directly receives wastewater of agricultural activities and rural sewage. Based on findings of biomonitoring and water BOD measurement, Cheshmeh-Ali River has relatively high-polluted situation and Benthos biological index is deteriorated at this river. | ||
