Abstract

Different factors affect concentration of dissolved substances in natural water systems. In the present study we investigated the discharge values and diverse substances concentration of Zarrineh-Rud river and compared them with theoretical values to find a pattern for discharge, salinity and concentration changes. For this purpose, quantitative and qualitative information of different stations of Zarrineh-Rud river were gained from Iran Water Resources Management Company. Among different stations we selected three of them. The comparison between actual values and the values obtained from linear, logarithmic and O’CONNOR model showed that the logarithmic model results have higher accuracy.
