Potential climate change can impact groundwater recharge. Climate change scenarios were constructed taking into account uncertainty concerning stochastic generation patterns of precipitation and change in the recharge. Because groundwater is directly connected to near-surface hydrologic processes, it intricately connected to the overall hydrologic cycle and could be directly affected by climatic change. Changes in groundwater recharge are likely to result from changes in the annual and seasonal distribution of precipitation. The relationship between the stochastic precipitation that infiltrates and recharges groundwater is the subject of active studies. This is an unprecedented and important research area. The goal of this research is to attempt to characterize impacts on groundwater recharge by developing potential precipitation patterns and simulating the groundwater recharge in a groundwater simulation model.
