چکیده:
Freshwater resources represent around 3% of all water on Earth, and less than 1% of that is available. Considering current conditions, as well as future predictions of need, freshwater resources cannot meet human needs. Thus, sweetening of the brackish water can be performed to provide freshwater for human use. Solar energy, because of Iran's climatic conditions, may be used for sweetening the brackish water. The objective of this study was to survey the lands using groundwater resources for the installation of solar desalinations. According to the goal, criteria and
indicators were identified by the analyses of previous studies’ data, Delphi method and the internal structure of measurements and indicators determined using the DEMATEL technique. Then, indicators were weighted using the analytic network process (ANP) method, and indicators’ suitable membership functions were defined using fuzzy logic. Indicators have been combined by the means of minimum function. Eventually, the areas were classified intofour classes. The results showed that among 250 scope studies, 20 scopes have been put in class one, and these arelocated in five provinces. The results also indicated that among the provinces of Iran, Yazd is located in an area withthe highest percentage of class one, and is ranked first. Comparisons of the obtained results with the climaticconditions of Iran confirmed the results.

Geographical information system (GIS) with a multi-criteria decision-making process (MCDM), a spatial decision support system and fuzzy logic can be used for the selection of optimum areas for the installation of solar desalinations.
Only one investigation has been done with the help of multi-criteria decision-making systems and geographical information systems to determine suitable areas for the installation of solar desalinations using groundwater.
The objective of this study was to survey the lands using groundwater resources for the installation of solar desalinations with the help of geographical information systems and multi- criteria decision-making systems.
Results Regarding the results obtained from this study, technical, economical and climatic criteria and eight indicators (Table 2) were selected as the most important factors in the survey for selecting the suitable lands for the installation of water desalination systems.
The results obtained from the current study have shown that central areas including Yazd, Isfahan, Kerman, Hormozgan and Semnan provinces are more susceptible for the installation of water desalination systems.
The results obtained from the current investigation have shown that suitable selections for the installation of water desalination can be performed using multi-criteria decision-making and geographic information systems (GIS)."
