The objective of this paper is to present a new system which can be appropriate for the determination of hydraulic behavior of faults assessment. In this paper an evaluation model, based on combining the Analytic Hierarchy Process (A H P) and the Fuzzy Delphi method (FDM), has been presented for assessing fault hydraulic behavior estimates. The research treats the hydraulic behavior of fault classification as a group decision problem, and applies the fuzzy logic theory as the criterion to calculate the weighting factors. In addition, about 87 faults were selected as the case study examples. After determining the hydraulic behavior of faults for each case, the equivalent permeability of fault zones has been estimated according to the proposed method. Afterwards, the results of actual permeability measurements have been compared with the estimated permeability, and then the relationship and difference between the proposed method and actual permeability were discussed. The introduced method has been examined successfully in faults of the Azad pumped storage power plant in Iran. The results show that since the majority of parameters regulating hydraulic behavior of faults have been considered in method, its results are very close to actual permeability of fault zones.
