The Demographics of Water: A Review of Water Ages in the Critical Zone

Paolo Benettin

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 and quantity. Most water age studies to date have focused on indivi ...

Velocities, Residence Times, Tracer Breakthroughs in a Vegetated Lysimeter: A Multitracer Experiment

Michaël Bensimon, Pierre Claude Jean Queloz, Andrea Rinaldo, Paolo Benettin

Flow velocities, residence times, and tracer breakthroughs at the lysimeter scale are affected by matrix properties and preferential flow. Despite their relevance to transport processes, however, the relative timing of preferential flow, and its link to tr ...

Ideas and perspectives: Tracing terrestrial ecosystem water fluxes using hydrogen and oxygen stable isotopes - challenges and opportunities from an interdisciplinary perspective

Natalie Claire Ceperley, Paolo Benettin, Jana Freiin von Freyberg

In this commentary, we summarize and build upon discussions that emerged during the workshop "Isotope-based studies of water partitioning and plant-soil interactions in forested and agricultural environments" held in San Casciano in Val di Pesa, Italy, in ...

Using SAS functions and high-resolution isotope data to unravel travel time distributions in headwater catchments

Andrea Rinaldo, Gianluca Botter, Paolo Benettin

We use high-resolution tracer data from an experimental site to test theoretical approaches that integrate catchment-scale flow and transport processes in a unified framework centered on selective age sampling by streamflow and evapotranspiration fluxes. T ...

Decomposing the Bulk Electrical Conductivity of Streamflow To Recover Individual Solute Concentrations at High Frequency

Paolo Benettin

The ability to evaluate stream hydrochemistry is often constrained by the capacity to sample streamwater at an adequate frequency. While technology is no longer a limiting factor, costs and sample management can still be a barrier to high-resolution water ...

Young runoff fractions control streamwater age and solute concentration dynamics

Andrea Rinaldo, Gianluca Botter, Paolo Benettin

We introduce a new representation of coupled solute and water age dynamics at the catchment scale, which shows how the contributions of young runoff waters can be directly referenced to observed water quality patterns. The methodology stems from recent tre ...

Transit times-the link between hydrology and water quality at the catchment scale

Paolo Benettin

In spite of trying to understand processes in the same spatial domain, the catchment hydrology and water quality scientific communities are relatively disconnected and so are their respective models. This is emphasized by an inadequate representation of tr ...

Reply to comment by Porporato and Calabrese on "Storage selection functions: A coherent framework for quantifying how catchments store and release water and solutes''

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter, Paolo Benettin

Tracking residence times in hydrological systems: forward and backward formulations

Andrea Rinaldo, Gianluca Botter, Paolo Benettin

In recent years, several papers contributed to the development and clarification of key theoretical issues underlying the formulation of transport by travel time distributions in catchments. Such a formulation provides a robust description of the temporal ...

Storage selection functions: A coherent framework for quantifying how catchments store and release water and solutes

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter, Paolo Benettin

We discuss a recent theoretical approach combining catchment-scale flow and transport processes into a unified framework. The approach is designed to characterize the hydrochemistry of hydrologic systems and to meet the challenges posed by empirical eviden ...

Linking water age and solute dynamics in streamflow at the Hubbard Brook Experimental Forest, NH, USA

Andrea Rinaldo, Gianluca Botter, Paolo Benettin

We combine experimental and modeling results from a headwater catchment at the Hubbard Brook Experimental Forest (HBEF), New Hampshire, USA, to explore the link between stream solute dynamics and water age. A theoretical framework based on water age dynami ...

Modeling chloride transport using travel time distributions at Plynlimon, Wales

Andrea Rinaldo, Gianluca Botter, Paolo Benettin

Here we present a theoretical interpretation of high-frequency, high-quality tracer time series from the Hafren catchment at Plynlimon in mid-Wales. We make use of the formulation of transport by travel time distributions to model chloride transport origin ...

Kinematics of age mixing in advection-dispersion models

Andrea Rinaldo, Gianluca Botter, Paolo Benettin

This paper investigates age mixing processes arising in advection-dispersion models, where large-scale travel and residence time distributions can be explicitly calculated based on the underlying velocity field. In particular, we analyze spatially integrat ...

Chloride circulation in a lowland catchment and the formulation of transport by travel time distributions

Andrea Rinaldo, Gianluca Botter, Paolo Benettin

Travel times are fundamental catchment descriptors that blend key information about storage, geochemistry, flow pathways and sources of water into a coherent mathematical framework. Here we analyze travel time distributions (TTDs) (and related attributes) ...
