Hydrodynamic model calibration from pattern recognition of non-orthorectified terrestrial photographs

Paolo Perona

This paper presents a remote sensing technique for calibrating hydrodynamics models, which is particularly useful when access to the riverbed for a direct measure of flow variables may be precluded. The proposed technique uses terrestrial photography and a ...

Ecomorphodynamics of rivers with converging boundaries

Benoît Crouzy, Peter Molnar, Paolo Perona

Many rivers worldwide show converging sections where a characteristic limiting front for vegetation establishment on gravel bars is observed. An important conceptual model was advanced in 2006 by Gurnell and Petts, who demonstrated that for the convergent ...

Flow-induced uprooting of young vegetation on river bedforms

Benoît Crouzy, Paolo Perona, Katharina Maria Edmaier

Riparian vegetation stabilizes sediment by its roots and henceforth impacts riparian morphodynamics. After germination or vegetative reproduction on river bars or islands, juvenile plants are exposed to a high risk of mortality due to uprooting by floods. ...

Biomechanics of plant anchorage at early development stage

Benoît Crouzy, Paolo Perona, Katharina Maria Edmaier

We propose a minimal model for the response of seedlings to pullout constraints. Central to our approach is the idea of capturing not only average mechanical properties but also the stochastic component of the uprooting process. Our model accounts on one h ...

Morphological, hydrological, biogeochemical and ecological changes and challenges in river restoration – The Thur River case study

Philipp Schneider, Edward Mitchell, David Andrew Barry, Paolo Perona, Juliane Hollender

River restoration can enhance river dynamics, environmental heterogeneity and biodiversity, but the underlying processes governing the dynamic changes need to be understood to ensure that restoration projects meet their goals, and adverse effects are preve ...

Influence of root characteristics and soil variables on the uprooting mechanics of Avena sativa and Medicago sativa seedlings

Benoît Crouzy, Paolo Burlando, Paolo Perona, Katharina Maria Edmaier

The success of seedlings and rejuvenated woody debris growing on river bedforms depends on the resistance to uprooting by flow provided by their simple root architecture. Avena sativa and Medicago sativa seedlings were used in flume experiments as prototyp ...

Experimental assessment of riverbed sediment reinforcement by vegetation roots

Paolo Perona

Vegetation roots are known to increase soil stability on hillslopes, crops and river banks, thus reducing slide hazards, surface erosion and general processes affecting lateral channel migration. Many studies have tackled this classical engineering problem ...

On quantifying ecologically sustainable flow releases in a diverted river reach

Paolo Perona, Lorenzo Gorla

Water demand for hydropower production has been increasing along with a growing awareness of the importance of preserving riparian ecosystems and their biodiversity. Some Cantons in Switzerland have begun replacing the inadequate concept of Minimum Flow Re ...

Obtaining natural-like flow releases in diverted river reaches from simple riparian benefit economic models

Paolo Perona

We propose a theoretical river modeling framework for generating variable flow patterns in diverted-streams (i.e., no reservoir). Using a simple economic model and the principle of equal marginal utility in an inverse fashion we first quantify the benefit ...

Impact of floods on the statistical distribution of riverbed vegetation

Benoît Crouzy, Paolo Perona, Katharina Maria Edmaier

Investigating the colonization of river bars by pioneer vegetation, we discuss how the balance between uprooting by flooding events and reinforcement of plant roots determines the ability for vegetation to colonize the riverbed. In order to access the comp ...

Biomass selection by floods and related timescales: Part 1. Experimental observations

Benoît Crouzy, Peter Molnar, Paolo Perona, Katharina Maria Edmaier, Zhe Jiang

Several research investigations have explored the interaction between morphodynamic and vegetation growth processes from both the modelling and the experimental viewpoints. Results have mainly been concerned with morphologic analyses of the effects of vege ...

Effects of streamflow variability on the vertical root density distribution of willow cutting experiments

Paolo Perona

The use of riparian tree cuttings for river rehabilitation relies on a good understanding of cutting survival and growth responses to environmental variables. A series of experiments aimed at studying the effects of water table fluctuation induced by strea ...

Stochastic dynamics of snow avalanche occurrence by superposition of Poisson processes

Benoît Crouzy, Paolo Perona

We study the dynamics of systems with deterministic trajectories randomly forced by instantaneous discontinuous jumps occurring according to two different compound Poisson processes. One process, with constant frequency, causes instantaneous positive rando ...

Biomass selection by floods and related timescales. Part 2: Stochastic modeling

Benoît Crouzy, Paolo Perona

We analyze the results from a flume experiment presented in a companion paper by Perona et al. [1] exploring the selective action of floods on pioneer riparian vegetation. We study the way seedlings react to periodic flow disturbances in the early stages o ...

Mechanisms of vegetation uprooting by flow in alluvial non-cohesive sediment

Paolo Perona, Katharina Maria Edmaier

The establishment of riparian pioneer vegetation is of crucial importance within river restoration projects. After germination or vegetative reproduction on river bars juvenile plants are often exposed to mortality by uprooting caused by floods. At later s ...

Impact of virus aggregation on inactivation by peracetic acid and implications for other disinfectants

Benoît Crouzy, Michael Jon Mattle, Tamar Kohn, Paolo Perona, Moritz Brennecke, Krista Rule Wigginton

Viruses in wastewater and natural environments are often present as aggregates. The disinfectant dose required for their inactivation, however, is typically determined with dispersed viruses. This study investigates how aggregation affects virus inactivati ...

Modern comprehensive approach to monitor the morphodynamic evolution of a restored river corridor

Paolo Perona

River restoration has become a common measure to repair anthropogenically-induced alteration of fluvial ecosystems. The inherent complexity of ecohydrologic systems leads to limitations in understanding the response of such systems to restoration over time ...
