Abstract
The success of the artificial recharge projects of aquifers need to recognition the appropriate points. The aim of this investigation is finding appropriate points for artificial recharge in “Kavir Meighan” basin in Markazi province. Because of that the Geographical Information System (GIS) is used. In this investigation. the method“Analytic Hierarchy Process (AHP)” is used to find suitable points. By using the opinion of the experts, the necessary criterion to choose suitable points are: Water Quality, Water Depth, Slope, Land use, Geology, Soil texture and the position of wells, springs and Qanats. In AHP methods the raster layer of used criterion was prepared. Then by using double comparison and Expert choice software, the weight of the any layers was made. In this method the maps were put together by overlap methods. After that, inappropriate points those are too close to wells, springs and qanats, were showed. Finally, the potential map of artificial recharge zone was prepared. In AHP method the potential map contents 29 zones, the total area of them is 14,770,183 square meters.
