The growth of technology has caused climate change around the world whose results are warming of the air, the occurrence of low precipitation periods, the conversion of snow into rain, and shortening of the length of snow remaining in the area. This research has analyzed Jahanbin basin and Shahrekord plain using water balance method and common indices. The results obtained using Standard Precipitation Index (SPI), Drought Magnitude (DM), Average Duration of Drought Intensity (ADI), Rainfall Anomaly Index (RAI), Standard Water Index (SWI) and Percentage of Normal Index (PNI), indices, indicated negative performance in the catchment area. Rainfall Anomaly index has risen to -4.56, even the SWI index shows that since 2000 the pressure on groundwater resources has increased, and withdrawals have exceeded the maximum allowable and water balance of the region is negative, which will continue until 2017, and the value of this index has reached -2.226. Moreover, the analysis of the moving average chart indicates the occurrence of drought periods in previous times, yet with the proper management of consumption, people have spent those times not many challenges. But, since 2007, about a decade ago, people have consumed water regardless of collective interest (benefit), optimal water consumption, and sustainable development, which had created an unfavorable condition.
