From precipitation to stream

TL;DRAbstract

Understanding the journey water makes from precipitation entering a catchment, traveling through soils, and the time it takes before it exits as stream water are questions of great relevance for both scientists and environmental managers. Natural stable isotopes such as δ¹⁸O and δ²H have been extensively used over the last decades to trace water through diverse catchments across the world. In this thesis I analyzed over 2500 isotope samples to create long-term time series of precipitation and stream water data, as well as studying spatial and temporal variability of flow pathways in the Krycklan catchment in Northern Sweden. Based on these isotope samples, I observed that streams draining forested catchments were fed by soil water from different horizons throughout the year. In contrast, stream water from mire dominated catchments was linked primarily to one hydrological active layer with the exception of the winter season when both catchment types showed influence of old/deep groundwa
