Special Issue Information

Dear colleagues,

The evaluation of aquifer recharge is essential to the quantitative evaluation of renewable groundwater resources and stream–aquifer interactions that is required to implement proper water policies at different spatial and temporal scales. However, aquifer recharge is a broad concept that includes natural sources from precipitation, aquifer transference, losing rivers, and snow melting; non-premeditated human-induced sources from irrigation and urban returns and losing channels and dams; and premeditated human-routed sources from different artificial infiltration techniques. Weather–land attributes, human water requirements, and global climatic forces determine the magnitude of natural sources, the existence of additional human-induced sources when water is used, and the need for human-routed sources in contexts of water scarcity.

A temporal perspective on how climate influences aquifer recharge and, therefore, renewable groundwater resources and surfacewater–groundwater interactions in general is needed. Over the last millennium, climate has determined the renewability of current groundwater resources in many drylands of the Earth. Current global climatic forces, which include the increasing influence of droughts and floods in different terrestrial latitudes, condition future water resources management policies. Finally, global climate scenarios predict the thresholds for future global water availability.

In this broad ‘aquifer recharge–climate’ framework, studies concerning climate influences on all aquifer recharge types that occur over different aquifer, catchment, and landscape typologies at different spatial and temporal scales of observation are welcome. Studies concerning climate influences on human-induced recharge and/or surfacewater–groundwater interactions are welcome. The analysis of climatic patterns and trends, which are drivers of the change in natural aquifer recharge from precipitation, will also be welcome.

In this work, we developed a new method to assess the impact of climate change (CC) scenarios on land subsidence related to groundwater level depletion in detrital aquifers. The main goal of this work was to propose a parsimonious approach that could be applied for any case study. We also evaluated the methodology in a case study, the Vega de Granada aquifer (southern Spain). Historical subsidence rates were estimated using remote sensing techniques (differential interferometric synthetic aperture radar, DInSAR). Local CC scenarios were generated by applying a bias correction approach. An equifeasible ensemble of the generated projections from different climatic models was also proposed. A simple water balance approach was applied to assess CC impacts on lumped global drawdowns due to future potential rainfall recharge and pumping. CC impacts were propagated to drawdowns within piezometers by applying the global delta change observed with the lumped assessment. Regression models were employed to estimate the impacts of these drawdowns in terms of land subsidence, as well as to analyze the influence of the fine-grained material in the aquifer. The results showed that a more linear behavior was observed for the cases with lower percentage of fine-grained material. The mean increase of the maximum subsidence rates in the considered wells for the future horizon (2016–2045) and the Representative Concentration Pathway (RCP) scenario 8.5 was 54%. The main advantage of the proposed method is its applicability in cases with limited information. It is also appropriate for the study of wide areas to identify potential hot spots where more exhaustive analyses should be performed. The method will allow sustainable adaptation strategies in vulnerable areas during drought-critical periods to be assessed. Full article
