Improved framework to estimate travel time and derived distributions in hydrological control volumes

Crossing properties of soil saturation, defined as the duration and excursion of soil saturation below and above certain thresholds, are key variables to ecosystem functioning and evolution by primarily influencing the plant and soil microbes physiological ...

Approximate analytical solutions for assessing the effects of unsaturated flow on seawater extent in thin unconfined coastal aquifers

David Andrew Barry, Zhaoyang Luo

This study develops approximate analytical solutions for seawater extent in unconfined coastal aquifers considering unsaturated flow, and assuming steady-state, sharp-interface conditions, for both constant flux (flux-controlled aquifers) and constant head ...

Toward catchment hydro-biogeochemical theories

Andrea Rinaldo, Paolo Benettin, Ilja van Meerveld, Li Li

Headwater catchments are the fundamental units that connect the land to the ocean. Hydrological flow and biogeochemical processes are intricately coupled, yet their respective sciences have progressed without much integration. Reaction kinetic theories tha ...

The impact of hydrograph variability and frequency on sediment transport dynamics in a gravel-bed flume

Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez

A laboratory study was undertaken to investigate how changes in flow regime and hydrograph shape (number of cycled hydrographs and duration of each hydrograph) together impact bedload transport and resulting bed morphology. Three hydrologic conditions (exp ...

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 ...

Space and time predictions of schistosomiasis snail host population dynamics across hydrologic regimes in Burkina Faso

Andrea Rinaldo, Theophile Mande, Francisco Javier Perez Saez

The ecology of the aquatic snails that serve as obligatory intermediate hosts of human schistosomiasis is driven by climatic and hydrological factors which result in specific spatial patterns of occurrence and abundance. These patterns in turn affect, join ...

Monitoring and prediction in Early Warning Systems (EWS) for rapid mass movements

Alexis Berne, Alessio Ferrari, Marc Schleiss, Dani Or

Rapid mass movements (RMM) pose a substantial risk to people and infrastructure. Reliable and cost-efficient measures have to be taken to reduce this risk. One of these measures includes establishing and advancing the State of Practice in the application o ...

Controls on the diurnal streamflow cycles in two subbasins of an alpine headwater catchment

Marc Parlange, Steven Vincent Weijs, Marc Calaf Bracons, Holly Jayne Oldroyd, Raphaël Mutzner

In high-altitude alpine catchments, diurnal streamflow cycles are typically dominated by snowmelt or ice melt. Evapotranspiration-induced diurnal streamflow cycles are less observed in these catchments but might happen simultaneously. During a field campai ...

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

Andrea Rinaldo, Paolo Benettin, Gianluca Botter

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) ...

Tidal influence on soil conditions in an intertidal creek-marsh system

David Andrew Barry

To understand better how tides affect the soil conditions of salt marshes, pore-water flow in a modeled 3-D creek-marsh system was simulated under the influence of both monochromatic and spring-neap tides. In analyzing the simulation results, we examined s ...
