Abstract
The solutions to deal with the water crisis are summarized into two strategies for managing water resources and extraction of new sources of water. In Iran, due to geographical and climatic conditions, water resources management has a high priority . One of the methods to control and store water in wet periods for using in dry periods is construction of underground dams. The most important problem in the development and creation of underground dams is the complexity of determining the suitable areas for the dams. Developing underground dams can be a viable solution to prevent land use change, the gradual drainage of groundwater and out of reach. The present study was conducted to find the underground dams using Boolean logic and for priority of underground dam sites using MCDM methods include AHP, ANP, VIKOR, TOPSIS and ELECTRE III in four provinces of Bushehr, Tangestan, Dashti, and Jam in southern Iran. The results obtained by Boolean logic showed that the total area of the studied site had about 305 km potential for underground dam construction. In the next step, according to Google Earth images and based on different indices including, axial length, reservoir, lithology, distance from village and roads, 23 potential axes were identified afterward, by extensive field surveys, among these 23 potential axes, 6 locations were identified as suitable locations. In order to prioritize these six areas, the MCDM models were used. Finally, the results of the MCDM models showed that sites have different ranks of 1 to 6 for constructing underground dams. In the end for determined the final rank using Copeland method that result showed Zayer Abbasi site was in the first priority and Faghih Hasenan site is in sixth priority. ANP and AHP method near the Copeland method.
