Forest ecohydrology governs critical interactions among water, carbon, and energy cycles, shaping ecosystem services such as carbon sequestration, biodiversity conservation, drought and flood mitigation, and climate regulation. Quantifying evapotranspiration, energy and water partitioning, and associated ecohydrological processes across both natural and man-made forests remains challenging due to complex biophysical drivers and landscape variability. This session aims to consolidate advances in forest ecohydrology and innovations of quantifying benefits of forests and management for water resources under global change, fostering dialogues across disciplines, research, and management. We welcome studies using field measurements, remote sensing, and modelling, including LLM-based synthesis and analysis. Contributions examining the interfaces of hydrology and forest management, climate variability and change, land use transitions, and disturbances such as wildfire and urbanization are particularly encouraged. We also seek work that connects ecohydrological understanding to landscape planning and Nature-based Solutions (NbS) with implications for addressing contemporary environmental and natural resource challenges.
