Linking water age and solute dynamics in streamflow at the Hubbard Brook Experimental Forest, NH, USA
Andrea Rinaldo, Paolo Benettin, Gianluca Botter
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 ...
American Geophysical Union2015Tracking residence times in hydrological systems: forward and backward formulations
Andrea Rinaldo, Paolo Benettin, Gianluca Botter
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 ...
Wiley-Blackwell2015Non-stationarity of solute travel time distribution observed in a controlled hydrologic transport volume
Andrea Rinaldo, Enrico Bertuzzo, Pierre Claude Jean Queloz, Luca Carraro, Gianluca Botter
Experimental data were collected over a year-long period in a transport experiment carried out within a controlled transport volume (represented by a 2m-deep, 1m-diameter lysimeter fitted with bottom drainage). The soil surface was shielded from natural ra ...
2014Non-stationarity in experimental travel time measured in a lysimeter: theoretical and modeling lessons from a simplified hydrological system
Andrea Rinaldo, Enrico Bertuzzo, Pierre Claude Jean Queloz, Luca Carraro, Gianluca Botter
Experimental data have been collected over a year-long period in a large weighing lysimeter. Natural climatic forcing occurs, except for rainfall which is artificially generated as a given Poisson process at a daily timescale. A constant water table is mai ...
2014The Signature of Hillslope Aspects on the Hydrologic Response of Snow-Covered Catchments
Andrea Rinaldo, Michael Lehning, Bettina Schaefli, Francesco Comola, Gianluca Botter, Pierfrancesco Da Ronco
The hydrologic response of Alpine catchments embeds the geomorphologic signature of the dominant drivers influencing snowmelt runoff dynamics. The focus of this work is the role of aspect as the main control on incoming radiation. We investigate the link b ...
2014Light and hydrologic variability as drivers of stream biofilm dynamics in a flume experiment
Andrea Rinaldo, Tom Ian Battin, Enrico Bertuzzo, Lorenzo Mari, Serena Ceola, Marino Gatto, Gianluca Botter
We run a comparative study of the results of flume experiments and several dynamic models reproducing the effects of streamflow variability on biofilm (i.e. periphyton) temporal dynamics. During the experiment, two contrasting flow regimes, characterised b ...
Wiley-Blackwell2014Chloride 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) ...
Amer Geophysical Union2013Catchment-scale herbicides transport: Theory and application
Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter
This paper proposes and tests a model which couples the description of hydrologic flow and transport of herbicides at catchment scales. The model accounts for streamflow components' age to characterize short and long term fluctuations of herbicide flux con ...
Elsevier Sci Ltd2013Hydrologic Variability Affects Invertebrate Grazing on Phototrophic Biofilms in Stream Microcosms
Andrea Rinaldo, Tom Ian Battin, Enrico Bertuzzo, Lorenzo Mari, Serena Ceola, Gianluca Botter
The temporal variability of streamflow is known to be a key feature structuring and controlling fluvial ecological communities and ecosystem processes. Although alterations of streamflow regime due to habitat fragmentation or other anthropogenic factors ar ...
Public Library of Science2013Kinematics of age mixing in advection-dispersion models
Andrea Rinaldo, Paolo Benettin, Gianluca Botter
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 ...
