Abstract :
Dozdozan plain is located in 80 kilometers south-east of Tabriz and is one of the most fertile plains of East Azerbaijan. The main economy of its residents is based on agriculture and as a result of the scarcity of surface water resources; agricultural sector is the major consumer of ground water. In this study, the application of Fuzzy Set theory for evaluation of ground water quality for agricultural purposes is used. In this research, seven ground water parameters from 50 wells were measured from 2012 to 2013 in Dozdozan plain. Based on Fuzzy Water Quality Model, the ground-water quality is classified in three categories; desirable, acceptable and unacceptable. Results showed only 17 samples from 50 wells come in desirable class with certainty level of 63.6 to 84 percent. About 28 samples classified in the acceptable category whose certainty level ranged from 48 to 64.5 percent and the remaining five samples were in not acceptable category with the maximum certainty level of 13.7 percent.
