Surface water-groundwater interactions play a fundamental role in regulating hydrological, geochemical, and ecological processes across diverse environments. Exchanges of water, heat, solutes, nutrients, and contaminants at the interface between rivers, lakes, wetlands, farmland, and aquifers influence water quality, ecosystem health, agricultural productivity, and biogeochemical cycling at multiple spatial and temporal scales. Understanding these interactions requires an interdisciplinary perspective that integrates physical flow processes, chemical transport and reactions, and biological activity.

This session invites contributions that advance the understanding of surface water-groundwater interactions from field observations, laboratory experiments, numerical modeling, remote sensing, and conceptual frameworks. Topics of interest include, but are not limited to: floods, hyporheic exchange, solute and heat transport, contaminant fate, nutrient cycling, paddy rice cultivation and irrigation, ecohydrological feedback, saltwater circulation in estuaries and intertidal zones, and the impacts of climate and land-use change. We especially encourage interdisciplinary studies that employ new methods or conceptual frameworks for quantifying coupled physical, chemical, and biological processes at the surface water-groundwater interface. We also welcome discussions on future challenges such as the improvement of predictive capabilities, engagement with socioeconomical dimensions, and implementation into policy frameworks.

Top submissions ranked through the convenors' review of this session will be highlighted as invited presentations.
