Using analytical hierarchy process for ranking suitable location of groundwater dams construction, case study: Northern slopes of Karkas mountains in Natanz

Decision making is a complex process with respect to different factors that should be considered in site selection of groundwater dams. These criteria include technical, environmental and socio-economic criteria. The study area is located in the northern slopes of the Karkas mountains. Construction of groundwater dams in dry rivers is one of the suitable ways for providing and development of water reservoir. In this research, we introduce a three step decision support system for groundwater damʹs site selection. In the first step, screening is done with using exclusionary criteria and 27 suitable areas are recognized. In the second step, the best gorge is recognized in each potential area. Then evaluation criteria for evaluating different groundwater dam sites are defined and with the assistance of analytical hierarchy process, as a powerful tool for decision making in multi-criteria evaluations, the most suitable sites for more detail research have been determined.
