Abstract

In areas where there is not a balance between discharge and Recharge from the aquifer, the water table is dropping and then reduction in quality and quantity of the water aquifer is caused, and as a result; artificial recharge is necessary. Using fuzzy logic operators to determine the suitable locations for artificial recharge may provide the desirable results. At this study attempted to use the fuzzy patterns to find the suitable location and provide management method, for artificial recharge of Nahavand’s aquifer, using GIS techniques. For this purpose, seven geographical information layers including slope, land use, surface infiltration, aquifer depth, aquifer quality, and net recharge and transmissivity were used. The results (as the output maps) showed that according to Fuzzy pattern, 5.94 percent of the total area (equivalent to 27.12 square kilometer area of the aquifer) which are widely scattered, rated good and very good in terms of artificial recharge of Nahavand’s aquifer.
