Abstract

The phenomenon of climate change is one of the most important environmental challenges that has been increased by the increasing emissions of greenhouse gases and has negative impacts on base resources such as groundwater resources. Therefore, it is essential that research is conducted to understand the impact of climate change on groundwater resources in the future period, to avoid the deterioration of the situation by proper management. Considering the importance of the subject in this study, the climatic model of LARS-WG and the GMS groundwater model were used to study the effects of climate change on groundwater under different scenarios in Kerman plain. In this regard, the climatic emission scenarios of A2, A1B and B1 of HADCM3 model was investigated in the period of 2011-2030 and to study the effect of climate change on groundwater drop, groundwater level was predicted using GMS software for the period 2012-2030 and the effect of climatic scenarios was studied on it. In order to groundwater modeling, the height of water in the piezometers was introduced to the model as a steady state in October 2002 and the values of hydraulic conductivity and recharge and boundary conditions were estimated. Then, the model was run for unsteady conditions for 2002 to 2013, and the groundwater level was predicted under different climatic scenarios for 2014-2030. The results showed that the average of groundwater drop in all four scenarios was -0.86, -5.85 and -9.19 meters (the first scenario), -9.26, -9.36 and -9.49 meters (the second scenario), -12.09, -12.21 and -12.28 meters (the third scenario) and -15.43, 15.55 and -15.58 meters (the fourth scenario) for A2, A1B and B1 scenarios, respectivelyThe phenomenon of climate change is one of the most important environmental challenges that has been increased by the increasing emissions of greenhouse gases and has negative impacts on base resources such as groundwater resources.
