Abstract

In recent years, limitation of water resources and the increasing trend of population growth cause the quantity issues on water supply. On the other hand, permanent and sudden pollution of waters as a biological threat has always been of high importance, because occurrence of biological pollution in water systems produces national crisis. However, since there are various and contradictory goals and utilities in reservoir systems, making proper decisions considering all aspects is a complex issue. A good strategy to compromise between the contradictory goals and utilities would be conflict resolution methods. To perform this study the allocations of drinking and agricultural waters of the Karaj dam, as one of the most strategic dams in Iran in the case of quality attacks, has been used. In this study, Nash model has been used as the conflict resolution method. According to the results, when there is a decrease in the quality aspects of water, Nash model assigns the priority to the quantity ones and allocates low-quality water to the consumers. Thus, a new conflict resolution method has been developed so that the allocations are modified according to the quality aspects. Thus, low-quality water is less allocated while more allocation is made along with an increase in the quality utility.
