At the catchment scale, ecohydrology – an interdisciplinary field merging principles from ecology, hydrology, biology, and geomorphology – is crucial for understanding the interactions among energy, water, and carbon cycles that sustain and define the functioning of catchments. Key ecohydrological fluxes include plant (evapo)transpiration, primary productivity, and autotrophic and heterotrophic respiration. The “green” and “blue” components of a catchment, representing its terrestrial and riverine environments, respectively, play significant roles in shaping these fluxes. In terrestrial environments, above-ground vegetation and below-ground biomass are the primary contributors. In riverine environments, flowing water (blue water) is not only essential for nutrient transport but also for nutrient processing.
This session aims to highlight interdisciplinary ecohydrological research, focusing on (but not limited to): theoretical, numerical modeling and remote sensing that improve our understanding of water and carbon fluxes in catchments and their interactions. Contributions may span different climatic contexts, from small to large catchments, to highlight the relevance of both green and blue water in changing environments.
