Scale-dependent effects of solar radiation patterns on the snow-dominated hydrologic response

Andrea Rinaldo, Michael Lehning, Bettina Schaefli, Francesco Comola, Mathias Thierry Pierre Bavay, Gianluca Botter, Pierfrancesco Da Ronco

Solar radiation is a dominant driver of snowmelt dynamics and streamflow generation in alpine catchments. A better understanding of how solar radiation patterns affect the hydrologic response is needed to assess when calibrated temperature-index models are ...

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

Andrea Rinaldo, Paolo Benettin, Enrico Bertuzzo, Gianluca Botter

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 ...

Light and hydrologic variability as drivers of stream biofilm dynamics in a flume experiment

Andrea Rinaldo, Enrico Bertuzzo, Tom Ian Battin, 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 ...

Catchment-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 ...

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) ...

Hydrologic Variability Affects Invertebrate Grazing on Phototrophic Biofilms in Stream Microcosms

Andrea Rinaldo, Enrico Bertuzzo, Tom Ian Battin, 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 ...

Kinematics 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 ...

Resilience of river flow regimes

Andrea Rinaldo, Gianluca Botter

Landscape and climate alterations foreshadow global-scale shifts of river flow regimes. However, a theory that identifies the range of foreseen impacts on streamflows resulting from inhomogeneous forcings and sensitivity gradients across diverse regimes is ...

Dominant controls on pesticide transport from tile to catchment scale: Lessons from a minimalist model

Andrea Rinaldo, Gianluca Botter

This paper proposes a minimalist modeling approach for characterizing pesticide concentrations in runoff from agricultural catchments across spatial scales. The model proposed is of an intermediate level of complexity between traditional chromatographic se ...

Catchment travel time distributions and water flow in soils

Andrea Rinaldo, Enrico Bertuzzo, Ludovico Nicotina, Gianluca Botter

Many details about the flow of water in soils in a hillslope are unknowable given current technologies. One way of learning about the bulk effects of water velocity distributions on hillslopes is through the use of tracers. However, this paper will demonst ...
