Coastal aquifers, pivotal freshwater reserves for millions worldwide, are increasingly vulnerable to seawater intrusion due to the joint impacts of climate change and intensive human activity. Rising sea levels, changing precipitation patterns, over-abstraction, land use change, and population growth intensify the stress on these valuable but fragile resources. As salinization threatens groundwater-dependent ecosystem health, agriculture, and urban water supplies, integrated approaches to monitoring, modelling, and managing coastal aquifers are urgently needed.

This session invites contributions that advance understanding, prediction, and management strategies for minimizing seawater intrusion and ensuring sustainable water resources in coastal regions. We aim to foster interdisciplinary discussion on innovative concepts, methods, and policies that support resilience under global-change scenarios.

We encourage submissions related to, but not limited to:

-Field and modelling studies of seawater-intrusion processes in coastal aquifers
-Impacts of climate change, including sea-level rise, extreme weather, and shifting recharge patterns, on groundwater salinization
-Effects of groundwater pumping, land-use change, and urbanization on aquifer vulnerability
-Advances in observation techniques, including hydrochemical and isotopic tracers, remote sensing, and geophysical methods
-Integrated management strategies and decision-support tools for sustainable groundwater extraction and adaptation
-Case stdies of coastal-aquifer restoration
-Nature-based solutions and managed aquifer recharge (MAR) to enhance coastal-aquifer resilience
-Socioeconomic, legal, and policy dimensions, including water quality, stakeholder involvement, and governance
-Multi-scale approaches, from local to global perspectives
