Karst springs of Belqis and Siah are among the abundant springs of Kohgiluyeh and BoyerAhmad provinces that are discharged from the Asmari limestones of the Lar anticline. The protruding surface of the Asmari limestones of the anticline is not proportional to the volume of water discharged from these springs. Based on the summary balance and hydrograph of the springs discharge, there are important water sources in the study area (including the Nile anticline) that can interfere with the feeding of the mentioned springs. Therefore, to evaluate this issue, the content of stable isotopes of oxygen (18O) and hydrogen (2H) of all water sources in the target area (discharge) and in the feeding area was determined for two periods (May 1402 and May 1403). Then, using these isotopic results and the local watershed line, the source of feeding of the springs in the target area was investigated, and the height of the feeding area and the possible feeding share of these springs from the water sources in the area were determined. The results showed that the elevation of the feeding area of the springs in the target area corresponds to their elevation in the Nile karst anticline. However, the share of water received by the Siah Spring is slightly higher compared to the water received by the Balqis Spring from the Nile anticline.
