Rivers are one of the most important water sources that play an important role in supplying water for various needs including agriculture, industry and drinking. Determining the flow regime and water quality of the river is an important factor in determining the health of the river. In this research, in order to determine the water quality and zoning of Karoon River (Bavi region) using IRWQISC, NSFWQI quality index and Liu index, monthly water sampling was done from April to March 1402. Three indicators and their presentation in the form of zoning maps, the comprehensive system of water quality assessment and management can be used by managers and decision makers to achieve better health and sustainability of water resources. According to the results of the IRWQISC index, the quality of the river is in the medium to relatively good category, while according to the NSFWQI index, the river water is in the poor to medium quality category, and according to the Liu index, it is in the relatively polluted category. It seems that NSFWQI index and Liu index are more strict, but there can be suitable indices to use and evaluate water quality for different purposes. Considering the water quality from the upstream stations to the downstream side of the studied area, the impact of industrial activities, agricultural drains and urban areas should not be ignored and water quality monitoring in this area.
