Abstarct: The main aim of this research is to assess the value of annual recharge in karstified limestone in the East and South East Ravansar in Kermanshah Province. The study area is located from 46 ° 40 ' to 46 ° 57' eastern longitude and from 34 ° 48 ' to 34 ° 35' northern latitude. Which fall in high Zagros zone. This area is mountaneous region which includes karstified limestone. In this research the GIS was applied for evaluating the value of recharge. For this purpose nine information laxyers including slope, aspect, lithology, lineament density, drainage density, precipitation, vegetation density, soil cover and karst features were prepared. After preparing the information laxyers for weighting to different parameters and final making decision, four different methods were used. The applied methods are experting judgment, proportion, affecting parameters and AHP. Finally, using overlapping the prepared laxyers, the obtained results from final map indicate the average value of recharge obtained from above mentioned methods is about 0.64 baxsed on the average calculated rate of infiltration and precipitation, the annual recharge of the limestone formations estimated at 77 MCM.
