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 …

Atmospheric water vapour residence time (WVRT) is an essential indicator of how
atmospheric dynamics and thermodynamics mediate hydrological cycle responses to …

Deep groundwater is an important source of drinking water, and can be preferable to
shallower groundwaters where they are polluted by surface-borne contaminants. Surface …

Headwater catchments are the fundamental units that connect the land to the ocean.
Hydrological flow and biogeochemical processes are intricately coupled, yet their respective …

Global warming is considered a major threat to Earth's lakes water budgets and quality.
However, flow regulation, over-exploitation, lack of hydrological data, and disparate …

The past decade has seen a remarkable expansion of studies that use mass-dependent
variations of triple oxygen isotopes (16 O, 17 O, 18 O) in isotope hydrology and isotope …

The response of the global water cycle to changes in global surface temperature remains an
outstanding question in future climate projections and in past climate reconstructions. The …

Groundwater resources play a key role in sustaining irrigated agriculture and providing
domestic water supplies in the trans-boundary Upper Indus River Basin. Understanding …

Most stored groundwater is 'fossil'in its age, having been under the ground for more than~
12 thousand years. Mapping where wells tap fossil aquifers is relevant for water quality and …

Abstract Characterization of the rainfall infiltration mechanism, whether piston or preferential
flow, through an unsaturated zone is necessary for groundwater resource assessment and …
