The Zayanderoud River stretches over 350 Km along a roughly west-east direction, originates in the Zagros Mountains on the west of Isfahan, and discharges into the Gavkhoni Swamp on the east of Isfahan. The Zayanderoud River supplies for the irrigation, domestic, and industrial water demands in Isfahan Province. In this paper, some water quality parameters of this river including EC, TDS, pH, HCO3, and Cl were simulated at different stations using artificial neural networks. The results showed an ascending trend for EC and TDS along the river. The trend in simulated HCO3 was found to be similar to that over the past few years and was equal to the long-term average. The trend for Cl was ascending at upstream stations and also similar to the long-term average at downstream stations. In general, the simulations of water quality parameters EC, TDS, pH, and HCO3 were evaluated to be highly satisfactory and the one for Cl satisfactory.
