Trees can regulate the water cycle through transpiration and evaporation. They also influence rainfall interception, infiltration and runoff. These processes have direct impacts on society’s well-being, and therefore are of great importance in landscape and urban water management.

This session focuses on studies that link the role of trees with landscape and urban hydrology, highlighting research that addresses tree–water interactions across multiple scales (neighbourhood, city, watershed) and the potential for trees to mitigate stormwater, improve water quality, and enhance climate resilience.

Approaches that may be discussed include field observations, modelling, remote sensing, and studies on the integration of trees as green infrastructure and stormwater management. The session aims to bring together diverse perspectives to synthesize findings, identify knowledge gaps, and highlight pathways for leveraging trees as critical components of a sustainable urban water system.
