The separation of storm hydrographs using stable isotope tracers dates back to the late
1960s. These studies ushered in a paradigm shift in how hydrologists conceptualized runoff …

Recent work in ecohydrology has shown that in some forested watershed systems, streams
and trees appear to return different pools of water to the hydrosphere. Thus far, evidence for …

Tracers in Hydrology and Water Research is a comprehensive overview of the application of
natural and artificial tracers in hydrology and environmental research. Taking a unique …

We tested for isotope exchange between bound (immobile) and mobile soil water, and
whether there is isotope fractionation during plant water uptake. These are critical …

Stable isotope ratios of water (δ18O, δ2H) have long been used to study a core question in
plant ecology and ecohydrology:'From where do plants take up water?'Indeed, decades of …

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 …

Cryogenic water extraction is the most widely used method to facilitate the laboratory
removal of soil pore water for isotopic analysis. However, recent studies have suggested that …

Core Ideas Bulk soil water isotopes have an evaporation signal, but mobile water isotopes
do not. These differences are time variant and linked to the volume and age of the mobile …

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 …

Rationale The stable isotope ratios of water (δ2H and δ18O values) have been widely used
to trace water in plants in a variety of physiological, ecohydrological, biogeochemical and …
