Numerical groundwater modeling was applied to investigate the climate change impact on the groundwater resources in the unconfined aquifer of Figuig basin of Moroccan eastern High Atlas. The stresses imposed to the model were derived from the IPCC (Intergovernmental Panel on Climate Change) emission scenarios and included recharge variation. The Figuig aquifer consists of carbonates, alternating marl-limestone, sandstone and alluvial dated of Jurassic and Quaternary age respectively. The limits of the model are topographic boundaries except for the western boundary which has been truncated. The model is composed of a single layer representing the whole thickness of the aquifer. It has been studied in steady state conditions. Modeling improves the understanding of the interactions between groundwater and surface waters by measuring the exchange of water flow. The decline in recharge due to climate change has a negative effect of groundwater resources, and therefore on the Figuig oasis. Currently, the drawdown of the groundwater resources has affected both the number of springs that supply the oasis.
