The study integrates rainfall-runoff modeling and stable isotope analysis to explore water distribution dynamics in northern catchments influenced by snow, spanning various sites in Sweden, Canada, Scotland, and the USA.
It ranks the importance of annual snowpack storage among the studied locations, with Wolf Creek being the most significant, and highlights how snowmelt rates and water flow paths impact soil and groundwater storage.
The research finds that factors like spring snowmelt timing, rainfall effects, and water flow path characteristics significantly influence stream water isotopic composition, revealing complex evaporation effects and spatial variability important for understanding plant water uptake.
