Locating Suitable Areas for Groundwater Recharge Using GIS and WLC (Qorveh Plain in Kurdistan Province)

In recent decades, the ever-increasing population, human needs, and changes in the consumption patterns of societies require the planning and management of water resources more than ever. Among the management strategies of underground water resources, we can point out the compensation of these resources through artificial nutrition and exploitation according to the capacity of aquifers. The studied area is located in the Qorve watershed with an area of ​​232.17 km2. In this research, which was carried out in Qorve plain in Kurdistan province, nine parameters of the slope, land use, the thickness of unsaturated alluvium, hydraulic conductivity, distance from the river, geology, electrical conductivity, aquifer transfer capability, and vegetation were investigated. The research method was based on the weighted-linear combination (WLC) method. The weights entered in this method were extracted by the AHP model in Super Decisions software. The results of this method showed that about 23.4% of the total area of ​​the plain and 54.4 km2 have a great value for feeding, and about 19% of the total area of ​​the plain is considered unsuitable.
