Abstract

The aim of this study is to determine suitable sites for artificial recharge in Oshtorinan Plain, Iran. In order to find out effective factors of artificial recharge. The thematic layers that are considered in this study are: The thickness of the unsaturated zones, Groundwater quality, Aquifer Transmissivity, hydraulic gradient, storage coefficient, slope, geology, land use and distance from surface water resources. A raster form map for different layers were prepared and arranged using Analytic Hierarchy Process (AHP) and weighted by an adhoc method. Then, the raster layers were integrated using the Wheighted Index Overlay Method. Thus, The artificial recharge map obtained divided the study area into 3 classes: suitable, moderately suitable and unsuitable according to their suitability for artificial recharge.
