This source is considered as one of the valuable resources of freshwater making it as one of the most valuable vital resources. Groundwater extraction, over the recent years, has given rise to decreased water level of this resource, that is, its level has decreased by an amount of 19.9m in the plain of Qorveh since 1986, 1987 until 2015. Therefore, the plain has become one of the forbidden plains out of 625 country plains. In recent years, integrating data of remote sensing (RS) and geographic information system (GIS) has increased for exploration of this valuable material. So that the combination of these two has become a point in the fields related to the issue of water. In this study, using (RS) and (GIS), data of potential areas of groundwater were identified. Layers created for site selection of aquifer in this study are as follows: geology, topography, slope, lineament, density of lineament, drainage, density of drainage, land use and vegetation of cover. Then, the final map was obtained using respective layers by means of fuzzy method in gis. The resulted map was divided into five groups of very good, good, average, weak and very weak. The results showed that the areas with good and very good potential with an area of 136461 hectare forming about half of the area of plain under study are located more in northern and eastern parts characterized by alluvial lands, vegetation and low slope, while regions with lower potential are located more in southern parts characterized by high slope areas covered with rock solid.
