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

Surface flow and subsurface flow constitute a naturally linked hydrologic continuum that has
not traditionally been simulated in an integrated fashion. Recognizing the interactions …

This text combines the science and engineering of hydrogeology in an accessible,
innovative style. As well as providing physical descriptions and characterisations of …

Water transit times and flow pathways are crucial elements in characterizing catchment
hydrologic response. Understanding their variability in space and time sheds light on the link …

Understanding the time water takes as it moves from rain or snowmelt through the terrestrial
system to arrive as stream discharge, or evapotranspiration (ET) is an important hydrologic …

This review presents the physical mechanisms generating residence time distributions
(RTDs) in hydrologic systems with a focus on steady-state analytical solutions. Steady-state …

Two main ways in which the progress of deglaciation in mountains can be identified and
monitored are through (a) meltwater loss over time as glaciers and permafrost melt and (b) …

Process‐based modeling of regional fluxes to groundwater is critical for understanding and
managing water quality, but the complexity of reactive transport processes makes …

The contribution of groundwater to streams is controlled by temporally and spatially variable
groundwater flow paths with distinctive travel times. The aggregated average travel time …
