The water crisis in terms of quantity and quality has become one of the growing concerns in human societies. In other hand, climate changes due to greenhouse gas emissions exacerbate conditions and the complexity of management decisions. So that the wet areas are not exempt from this problem. Accordingly, in this study sodium adsorption ratio trend were investigated in deep wells Gharesoo basin in Golestan province under climate changes conditions. HadCM3 model has been used during 2011-2100 under three scenarios (i.e. A1B, A2 and B1). In the next step 16 deep wells located in this basin were studied on the basis of the average SAR during the base period which divided into four categories and were introduced to the Anfis model. After that the best membership functions and a model has been selected during the months of April and October was run for next years. The results showed the SAR in the fourth group in all periods was increased in comparison to the baseline in both months. The third group was additive in April and just in scenario in A1B was increased in October and in two other scenarios was decreased. The second group was decreased in April and was increased in October. The first group is often decreased in the first thirty years and was increased in the remaining periods. Finally, we can find how future changes of SAR percent will affect to the baseline by an initial value as well as changes in climate parameters.
