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 …

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

Transit time is a fundamental catchment descriptor that reveals information about storage,
flow pathways and source of water in a single characteristic. Given the importance of transit …

Transport processes and pathways through many hydrodynamic systems vary over time,
often driven by variations in total water storage. This paper develops a very general …

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 …

The age, or residence time, of water is a fundamental descriptor of catchment hydrology,
revealing information about the storage, flow pathways, and source of water in a single …

The role of fluid residence time and catchment length scales in controlling the chemical
composition of rivers is evaluated by comparing numerical simulations and scaling …

Protecting or restoring aquatic ecosystems in the face of growing anthropogenic pressures
requires an understanding of hydrological and biogeochemical functioning across multiple …

The effects of impervious area, septic leach-field effluent, and a riparian wetland on runoff
generation were studied in three small (0.38–0.56 km2) headwater catchments that …

We propose a mathematical framework for the general definition and computation of travel
time distributions defined by the closure of a catchment control volume, where the input flux …
