Abstract The time that water takes to travel through the terrestrial hydrological cycle and critical zone is of great interest in Earth system sciences with broad implications for quality quantity. Most age studies date have focused on individual compartments (or subdisciplines) such as unsaturated or saturated zone, vegetation, atmosphere, rivers. However, recent shown processes at interfaces between (e.g., soil‐atmosphere soil‐groundwater) govern distribution fluxes these thus can greatly affect times. variation from complete nearly absent mixing affects ages compartments. This especially case highly heterogeneous top vegetation bottom groundwater storage. Here, we review a wide variety about provide (1) an overview new prospects challenges use tracers study ages, (2) discussion limiting assumptions linked our lack process understanding methodological transfer estimations disciplines compartments, (3) vision how improve future interdisciplinary efforts better understand feedbacks soil, groundwater, surface control zone.

Abstract Headwater catchments are the fundamental units that connect land to ocean. Hydrological flow and biogeochemical processes intricately coupled, yet their respective sciences have progressed without much integration. Reaction kinetic theories prescribe rate dependence on environmental variables (e.g., temperature water content) advanced substantially, mostly in well‐mixed reactors, columns, warming experiments considering characteristics of hydrological at catchment scale. These shown significant divergence from observations natural systems. On other hand, theories, including transit time theory, substantially not been incorporated into understanding reactions Here we advocate for development integrated hydro‐biogeochemical across gradients climate, vegetation, geology conditions. The lack such presents barriers mechanisms forecasting future Critical Zone under human‐ climate‐induced perturbations. Although integration has started co‐located measurements well way, tremendous challenges remain. In particular, even this era “big data,” still limited by data will need (1) intensify beyond river channels characterize vertical connectivity broadly shallow deep subsurface; (2) expand older dating scales reflected stable isotopes; (3) combine use reactive solutes, nonreactive tracers, (4) augment environments undergoing rapid changes. To develop it is essential engage models all stages model‐informed collection strategies maximize usage; adopt a “simple but simplistic,” or fit‐for‐purpose approach include process‐based models; blend data‐driven framework “theory‐guided science.” Within hypothesis testing, model‐data fusion can advance mechanistically link catchments' internal structures external drivers functioning.

Global warming is considered a major threat to Earth's lakes water budgets and quality. However, flow regulation, over-exploitation, lack of hydrological data, disparate evaluation methods hamper comparative global estimates lake vulnerability evaporation. We have analyzed the stable isotope composition 1257 we find that most depend on precipitation groundwater recharge subsequently altered by catchment evaporation processes. Isotope mass-balance modeling shows ca. 20% inflow in lost through 10% arid temperate zones experience extreme evaporative losses >40 % total inflow. Precipitation amount, limnicity, wind speed, relative humidity, solar radiation are predominant controls evaporation, regardless climatic zone. The promotion systematic isotopic monitoring provides direct approach detect impacts catchment-scale changes water-balance trends.

Landscapes receive water from precipitation and then transport, store, mix, release it, both downward to streams upward vegetation. How they do this shapes floods, droughts, biogeochemical cycles, contaminant the health of terrestrial aquatic ecosystems. Because many key processes occur invisibly in subsurface, our conceptualization them has often relied heavily on physical intuition. In recent decades, however, much intuition been overthrown by field observations emerging measurement methods, particularly involving isotopic tracers. Here we summarize surprises that have transformed understanding hydrological at scale hillslopes drainage basins. These forced a shift perspective process conceptualizations are relatively static, homogeneous, linear, stationary ones predominantly dynamic, heterogeneous, nonlinear, nonstationary. ▪Surprising novel measurements transforming functioning landscapes.▪Even during storm peaks, streamflow is composed mostly stored landscape for weeks, months, or years.▪Streamflow tree uptake originate different subsurface storages seasons’ precipitation.▪Stream networks dynamically extend retract as wets dries, stream reaches lose flow into underlying aquifers.
