Sabzab and Bibitalkhone Karst springs are the main discharging points of the Kamarun and Pabdeh karstic anticlines (Asmari dolomite and limestone) in Khuzestan province. The exposed surface of both anticlines are not sufficient to feed the aforementioned springs. According to the general water balance estimation and the discharge hydrographs of springs, there are important water resources in the region (including the Shahid Abbaspour dam reservoir as well as the Shirgun anticline in the vicinity of the host anticlines of springs) which could contribute in feeding the springs. All of water resources in the target (discharge) and the recharge area were sampled during two rainy (February 2013) and dry (July 2013) periods. The origin of the spring's waters in the target area evaluated using these isotope data, as well as the local meteoric water line (LMWL) in the study area. The average elevation of the recharge area and the probable recharge fraction from the water bodies resources in the region estimated for the springs. The results show that the recharge area elevation of the springs in the target area corresponds to the recharge area elevation in the neighboring karstic anticline. It was also revealed that the Shahid Abbaspour dam reservoir participate in recharging the Sabzab spring. However, the volume of input water from the dam reservoir in comparsion to Shirgun karstic catchment is not considerable.
