Sarroud Dam is located in the north of Khorasan Razavi Province in the city of Kalat. Being located in a fault zone, it is necessary to inject the cut-off wall. Using remote sensing techniques, geographic information system, Landsat satellite imagery and field observations in this research, it was specified that the dam has been located within the range of the Sarroud Fault. According to this, the foundation of axis, overflow shoot and the sides of the dam were evaluated in terms whether or not being affected by fault activities. the zonation of the cut-off wall based which the engineering geology parameters & permeability tests in the Arc GIS was undertaken, was, subsequently, weighed & interpolated through the neighbor method. The outcome was preparation of the zonation maps of the injection/grouting? axis at the cut-off wall. Moreover, the zonation map for the most widely-injected areas was prepared using the Hierarchy Model(AHP).

Keywords: Key words: Sarroud dam, grouting injection, engineering geological parameters, permeability, Cut - off wall Zonation, AHP models
