Catchment residence and travel time distributions: The master equation

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter

The probability density functions (pdf's) of travel and residence times are key descriptors of the mechanisms through which catchments retain and release old and event water, transporting solutes to receiving water bodies. In this paper we analyze theoreti ...

Comparative study of ecohydrological streamflow probability distributions

Andrea Rinaldo, Enrico Bertuzzo, Serena Ceola, Gianluca Botter

We run a comparative study of ecohydrological models of streamflow probability distributions (pdfs), p(Q), derived by Botter et al. (2007a, 2009), against field data gathered in different hydrological contexts. Streamflows measured in several catchments ac ...

Stochastic modeling of nutrient losses in streams: Interactions of climatic, hydrologic, and biogeochemical controls

Andrea Rinaldo, Gianluca Botter

We present an analytical, stochastic approach for quantifying intra-annual fluctuations of in-stream nutrient losses induced by naturally variable hydrologic conditions. The relevance of the problem we address lies in the growing concern for the major envi ...

Impact of stochastic fluctuations in storage-discharge relations on streamflow distributions

Andrea Rinaldo, Enrico Bertuzzo, Samir Suweis, Gianluca Botter

In this paper we extend recent theoretical results on the structure of the probability density function of streamflows forced by stochastic rainfall sequences. Our extension is aimed at incorporating an additional, independent source of variability assumed ...

Daily streamflow analysis based on a two-scaled gamma pulse model

Andrea Rinaldo, Gianluca Botter

In this paper, we develop a simple analysis method to infer some properties of the watershed processes from daily streamflow data. The method is built on a simple streamflow model with a link to rainfall stochasticity, which characterizes the streamflow as ...

Transport in the hydrologic response: Travel time distributions, soil moisture dynamics, and the old water paradox

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter

We propose a mathematical framework for the general definition and computation of travel time distributions defined by the closure of a catchment control volume, where the input flux is an arbitrary rainfall pattern and the output fluxes are green and blue ...

Natural streamflow regime alterations: Damming of the Piave river basin (Italy)

Andrea Rinaldo, Gianluca Botter

A novel approach is proposed to estimate the natural streamflow regime of a river and to assess the extent of the alterations induced by dam operation related to anthropogenic (e. g., agricultural, hydropower) water uses in engineered river basins. The met ...

Nonlinear storage-discharge relations and catchment streamflow regimes

Andrea Rinaldo, Gianluca Botter

Nonlinear storage-discharge relations may explain important hydrologic features frequently observed under a variety of environmental conditions. In this paper the catchment dynamic storage problem is addressed by incorporating nonlinear storage-discharge r ...

Inferences from catchment-scale tracer circulation experiments

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter

In this paper the mechanisms determining the mobilization and transport of solutes driven by rainfall through runoff pathways at catchment scales are investigated through the analysis of tracer experiments. The hydro-chemical response of a small catchment ...
