Abstract :
Among surface water sources, rivers have a greater potential for pollution due to their long length and passage through various urban and industrial areas. Monitoring and control of surface water for its various uses is necessary and essential in order to make high quality water available to consumers for various uses. The main purpose of this study is the qualitative zoning of Karun River in the range of Shahid Abbaspour Dam to Ahvaz. In this study, using nine quality measuring stations, changes in water quality of Karun River in the period of 12/1396 to 06/1397 were investigated. Then the quality for agricultural consumption was determined using the Wilcox index. Then, with Chemistry software, the quality for industrial consumption and based on the total hardness was also evaluated. The results showed that, in the period of 12/13/2017 to 06/06/1397, the stations of Mollasani, Ahvaz, Valiabad and Indika Tang Dolab with very salty quality - were unsuitable for agriculture and the rest of the stations were in the appropriate category. For industrial use, the stations of Shahid Abbaspour Dam Lake and Shahid Abbaspour Dam spring have water corrosive quality, the other stations have sediment quality. Quality assessment based on total hardness, Shahid Abbaspour Dam Lake, Gotvand and Cheshmeh stations of Shahid Abbaspour Dam have hard water quality and other stations have very hard quality. The amount of BOD parameter in March 2017, all stations in the region are in good condition.
