Abstract
Water shortage is one of the most critical problems all around the world, especially in arid and semi-arid regions. Using groundwater can be an efficient solution in such lands. Although significant care and appropriate water resource management strategies are required to be implemented. Nowadays, subsurface dams (SSD) are widely used worldwide since they are proved to have advantages over surface dams in some cases. Selection of the suitable site for SSD construction is critical. This selection is made based on advantages and disadvantages of each location. Multi-criteria decision-making methods (MCDM) is an efficient method for optimum site selection. In this study, 10 regions were chosen as alternatives for construction of subsurface dams in Isfahan province of Iran. These alternatives were then ranked using ELECTRE I, II and modified ELECTRE III based on geological, hydrological, climatological and socio-economical criteria. Results from different ELECTRE methods are combined by applying the grade average, and Borda and Copeland ranking strategies. Application of an advanced MCDM method reduced uncertainties in subsurface dams (SSD) site selection. Alternative 5 (Hoseinabad) was introduced as the best location for subsurface dam construction. This methodology can be used as a basis for more detailed field investigations.
