Abstract

© 2020, Springer Nature Switzerland AG. Due to the climate change and global warming, water shortage is known as a serious worldwide issue particularly in arid and semi-arid regions. Utilization of subsurface dams (SSD) could be a solution to this matter, but finding a suitable site for construction of a SSD is an engineering challenge. Selection of the optimum location is carried out by evaluating different positive and negative criteria. Criteria are combined by means of multi-criteria decision-making methods (MCDM), such as AHP, ANP, TOPSIS and other well-known methods. In these research, because of the complexity of the decision and this fact that the results in other MCDM methods are very similar to each other, we choose ELECTRE method which is performed for site selection of SSDs. 10 regions out of 50 are studied as SSD alternatives in Isfahan province of Iran. For performing ELECTRE method, 14 criteria have been defined based on four different aspects of SSD construction that are hydrogeology, socio-economy, geology and climate change. The most important criteria include average annual rainfall, area of upper basin, distance from villages and stream slope. The modified ELECTRE III method was used to rank the alternatives from the most suitable choice for constructing a subsurface dam to the least. Hoseinabad area was finally selected to construct the sub-surface dam. Application of an advanced MCDM method like ELECTRE reduces some uncertainties in SSD site selection and this developed methodology can be used as a base for more detailed field investigations.
