Delineation of groundwater potential using AHPFuzzy (A Case Study: Romeshgan plain)

Groundwater is one of the most important of water sources for human life. Because of limitation of surface water sources of several regions of Iran, groundwater can be considered as the most appropriate sources for supplying these regions. Currently, Remote Sensing and GIS are considered as one of the most powerful and affordable tools for exploration of groundwater. Talents of this study are identification of high potential regions of the Romeshgan plain using by AHPFuzzy, Remote Sensing techniques and GIS. Based The lithological, thick alluvium, landuse, elevation, slope, drainage density, fault density, temperature and rainfall layers were prepared using Fuzzy method in GIS environment and based on geological, hydrological, structural, topographical data, satellite images ETM and field visit. These maps were weighted using pair comparison in AHP method. The maps of mentioned factors were prepared by applying weights to each criterion and according to their importance in delineation of groundwater potential. Finally, the final maps were provided using the AHP-Fuzzy overlapping approach. Results indicate that about 7.37, 10.12, 22.25, 20.46 and 39.79 percent of study area fall in the areas with very low, low, medium, high, very high for Delineation of groundwater potential.
