Cover Story: Groundwater resources worldwide are facing a decline in hydraulic heads due to the combined impacts of urbanization and climate forcings. This study evaluated the impact of these two forcings on groundwater resources during the Pre- and Post-Urbanization Periods (PreUP:1980–1988; PostUP:2000–2008) within a multi-layer aquifer system. Our findings indicate a significant decrease in hydraulic heads of about 5 m from the PreUP to PostUP in the unconfined aquifer, influenced by land use and climate change. In contrast, the average head decline in deep confined aquifers is about 4 m and is mainly influenced by long-term climatic variations. The impervious land use types experienced greater declines in hydraulic heads than permeable areas due to impeded groundwater recharge, which exacerbates the climate variability effect.
