The consequences of climate variability and change have potential implications for recharge and ground-water resources worldwide. Climate change, whether due to natural variability or as a result of human activity, may alter the spatiotemporal controls on rates, location, and timing of recharge. These changes can alter more than the immediate ground-water systems but also can indirectly affect baseflow, stream temperatures, and riparian and other ecosystems. Therefore, an improved understanding of the response of recharge to varying climates is necessary to accurately assess current availability and future sustainability of ground-water resources. This session welcomes all presentations on topics that advance process-level understanding between a changing climate and recharge. We particularly encourage oral presentations of studies exploring novel approaches for estimating, simulating, and forecasting recharge in response to paleo-climate conditions; natural-climate cycles, such as the El Niņo/Southern Oscillation; or projected global warming due to human activity.
