Converting great amount of parameters into a simpler expression<br />and enabling easy interpretation of data are the main purposes of water quality indices.<br />The main aim of this study is to plan effective water resources management system for<br />Karun River by combination of CCMEWQI and Geographic Information System (GIS).<br />The investigation was carried out to set a management plan through exploratory and<br />spatial analysis of physicochemical water parameters of collected samples from 10<br />stations over one year period. Since all indices were obtained from index, river zoning<br />was conducted by GIS. Moreover, trace metals concentrations (As, Cr, Cd, Fe, Zn, Mn,<br />and Al) ranged in safer limit. The highest values of F1 belonged to aquatic life and the<br />lowest ones belonged to irrigation. Aquatic life and drinking uses received the maximum<br />values of F2. The lowest values were devoted to livestock and then recreation uses. It was<br />inferred from index that the quality of the Karun River is principally impacted by high<br />turbidity, TDS, NO3, SO4, and PO4 due to high suspended sediment loads. The main<br />cause is incremental agricultural, industrial, and residential effluents. Amongst stations,<br />station one only received the priority for drinking water supply and recreation. https://jpoll.ut.ac.ir/article_57875_2c0f53dee17ccd6ed509706d91591dce.pdf
