During the passage of precipitation through the soil–plant–atmosphere interface, water and solutes are redistributed by the plant canopy, subsurface flow and transport processes. Many of these dynamic interactions between vegetation and soil are not yet well understood. This special issue brings together the vibrant community addressing a better understanding of ecohydrological processes taking place between the canopy and the root zone. We invite studies that use innovative methods to investigate throughfall, stemflow, hydraulic redistribution, soil water movement, and root water uptake in various environments to shed light on how water and solutes are routed in the thin layer covering the terrestrial ecosystems. Submissions to this special issue may further include open questions and new opportunities within the ecohydrological community regarding methodological developments such as the analysis of stable isotope, soil moisture, throughfall or solute dynamics. We encourage both field scientists and modelers to contribute to the special issue and especially welcome studies that follow a multi-disciplinary approach.
