Abstract :
Nowadays, the subject of hygienic drinking water is one of the main concerns of most countries in the world. In the seaside areas in south of Iran, this is more easily observable due to different factors including the population growth, limitation of freshwater resources, development of famine phenomenon and the increase in temperature, etc. Therefore, the construction of the desalinators in order to convert saline water into drinking water, is of great significance. In this research, a zone across the southern coast of Bushehr province was studied, and the potential of the area for locating water desalinators were analyzed. Analysis of the data were done with analytic hierarchy process (AHP) method in Expert Choice software and GIS. A number of 13 criteria were weighted in the form of three main indexes, borders, and natural factors. The weighted layers were merged and the final map was produced. Results of the study indicate that 13.15% of the region has a very high potential for the construction of desalinators, 28.37% high potential, 30.45% has an average potential, and 21.45% and 6.57% of the region have low and very low potential, respectively. Kaky, Abdanof, Bardestan and Siraf have a considerable potential for accommodating water desalination facilities and in general the northern parts of the case study area are more suitable for this purpose.
