Groundwater recharge is a key component of the hydrological cycle and is essential for sustaining groundwater resources, ecosystems, agriculture, and water security. Climate change, land-use change, urbanization, and changing water-management practices are altering the magnitude, timing, and spatial distribution of recharge, creating new challenges for groundwater assessment and sustainable management.

This session brings together researchers to advance understanding of recharge processes under changing environmental and anthropogenic conditions. We welcome contributions on climate impacts, land-use and agricultural effects, natural and managed aquifer recharge, groundwater–surface water interactions, and recharge estimation using field observations, tracers, remote sensing, geophysics, and modelling. We also invite studies using data-driven and machine-learning approaches to quantify and predict recharge.

Contributions addressing uncertainty, scaling, emerging methodologies, and implications for groundwater sustainability and water security are particularly encouraged. The session aims to foster interdisciplinary discussion on how improved understanding and quantification of recharge can support resilient groundwater management in a changing world.
