Scope
The hydrological processes governing surface-subsurface interactions involve dynamic exchange of water between surface water and groundwater systems.
These processes are fundamental to the water cycle, influencing water quantity, quality, and distribution across landscapes.

Key concepts include infiltration, percolation, recharge, baseflow, and evapotranspiration, governing water movement between surface and subsurface environments. Understanding these interactions is essential for effective water resource management, as they impact availability, flood dynamics and contaminant transport. Climate change and land-use alterations impact these complex hydrological interactions.

We invite contributions that explore innovative approaches to understanding and managing surface-subsurface water interactions. This includes advanced modelling techniques, field measurement methods, and integrated management strategies. We seek studies addressing practical applications in water resource planning, ecosystem conservation, and climate adaptation. Presentations on the implications for water quality, quantity, and ecosystem resilience are of particular interest. We also welcome discussions on future challenges such as improving predictive capabilities and integrating these concepts into policy frameworks. This session aims to encourage interdisciplinary dialogue, enhance our understanding of these critical hydrological processes and the management in a changing environment.
