Projected impacts of climate change on groundwater systems are commonly simulated using models at local to global scales . The relations between climate change and groundwater are more complex than those embedded in current numerical models . For instance, groundwater systems register effects of drought with several years of lag effect, and aquifer response times to changes in hydraulic forcing also vary across aquifers . For instance, long groundwater response times can buffer drought impacts and lengthen recovery times to sustained drought events .
