Estimating groundwater availability

A study that modeled groundwater recharge in all carbonate rock regions in Europe, Northern Africa, and the Middle East finds that a simulation that included subsurface heterogeneity revealed an altered recharge sensitivity to climate variability, compared with a simulation with subsurface homogeneity, and that present and future groundwater recharge rates are respectively up to four and five times higher than previous projections that assumed subsurface homogeneity, suggesting a need for revised groundwater availability estimates in heterogeneous subsurface regions. - Read at PNAS
