The time that water takes to travel through the terrestrial hydrological cycle and the critical
zone is of great interest in Earth system sciences with broad implications for water quality …

Water stable isotopes (18O and 2H) are widely used as ideal tracers to track water through
the soil and to separate evaporation from transpiration. Due to the technical developments in …

In spite of trying to understand processes in the same spatial domain, the catchment
hydrology and water quality scientific communities are relatively disconnected and so are …

Measurements of δ2H and δ18O composition of pore waters in saturated and unsaturated
soil samples are routinely performed in hydrological studies. A variety of in‐situ and lab …

Water travel times reflect hydrological processes, yet we know little about how travel times in
the unsaturated zone vary with time. Using the soil physical model HYDRUS‐1D, we derived …

The vadose zone plays a crucial role in the water cycle for storing water, providing water to
vegetation and transporting solutes or degrading contaminants. Earth scientists have long …

There is increasing interest in improving understanding of evaporation within a catchment
for an enhanced representation of dominant processes in hydrological models. We used a …

The relative importance of catchment's water provenance and flow paths varies in space and
time, complicating the conceptualization of the rainfall‐runoff responses. We assessed the …

Transit time distributions (TTDs) are crucial descriptors of flow and transport processes in
catchments, which can be determined from stable water isotope data. Recently, the young …

Ecohydrological processes are often evaluated by studying the fate of stable water isotopes.
However, isotopic fractionation during evaporation is often ignored or simplified in current …
