climatechange impact on groundwater budgetof shahrekord plain in the future periods

high greenhouse gas emissions, leads to the global warming. global warming and climate change resultant from it, has significant effects on various systems, such as water resources, agriculture and environment.this study, climate change impact on budget aquifer was investigated by applying two different scenarios of wells operations. for this purpose, the gms software was applied to simulate fluctuations of groundwater table in shahrekord plain caused by the climate change from 2015 till 2029. the model was calibrated for the steady and unsteady states, both. then the output of hadcm3-a2 model was used to simulate the temperature and rainfall in thesame period of time. the output was downscaled for the region by larse-wgsoftware.in order to access an efficient plan for the studied aquifer, two scenarios were considered including 10 and 20 percent of increase in the operation for mentioned period. according to the results, annual rainfall and temperature will both increase at the end of the period by the average of 12 percent and 0.4 celsius, respectively. also, due to the mentioned 10 and 20 percent of increase in the operation, the aquifer storagewill be reduced6.3 and 10.94 million cubic meters respectively.
