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 …

Abstract Groundwater 18O/16O, 2H/1H, 13C/12C, 3H, and 14C data can help quantify
molecular movements and chemical reactions governing groundwater recharge, quality …

Headwaters are hotspots of carbon dioxide (CO2) evasion from rivers. While emerging
evidence suggests that groundwater contributes disproportionately to CO2 in headwater …

Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

The idea was that, given our limited knowledge of catchment characteristics and
understanding of catchment responses, it would be impossible to map that catchment to a …

Water transit time is now a standard measure in catchment hydrological and ecohydrological
research. The last comprehensive review of transit time modeling approaches was …

Snowfall may have different stable isotopic compositions compared with rainfall, allowing its
contribution to potentially be tracked through the hydrological cycle. This review summarizes …

Observations and data from long‐term experimental watersheds are the foundation of
hydrology as a geoscience. They allow us to benchmark process understanding, observe …

We introduce EcH 2 O-iso, a new development of the physically based, fully distributed
ecohydrological model EcH 2 O where the tracking of water isotopic tracers (2 H and 18 O) …

Subsurface contamination due to excessive nutrient surpluses is a persistent and
widespread problem in agricultural areas across Europe. The vulnerability of a particular …
