Ecomorphodynamic conditions for the emergence of river anabranching patterns

Paolo Perona, Benoît Crouzy

The appearance of the regular vegetated ridge patterns observed in some ephemeral rivers of semi-arid regions (Nanson, Tooth, & Knigthon 2002) has previously been explained by hydraulic arguments (optimization of the bed load transport capacity, see Huang ...

Stability analysis of ecomorphodynamic equations

Paolo Perona, Benoît Crouzy

In order to shed light on the influence of riverbed vegetation on river morphodynamics, we perform a linear stability analysis on a minimal model of vegetation dynamics coupled with classical one- and two-dimensional Saint-Venant-Exner equations of morphod ...

Frontiers of (Pareto) Optimal and Sustainable Water Management for Hydropower and Ecology

David Andrew Barry, Paolo Perona, Amin Niayifar, Pierre Razurel

River regulation alters the natural flow regime of streams with consequent impacts on terrestrial and aquatic habitats of the riparian zone. The severity of such impacts can be modulated by changing the redistribution rules at water intakes and reservoirs. ...

Towards unified scaling relationships for gravel-bed and sand-bed rivers

Paolo Perona, Giulio Calvani

Laboratory flume experiments and field investigations demonstrated the existence of dynamic equilibrium conditions for river channels, according to the hydraulic (flow discharge, water depth) and morphological (bed slope, grain size distribution, cross-sec ...

Experimental characterization of root-reinforced riparian sediment deposits in a restored and widened river course

Giovanni De Cesare, Paolo Perona

The Arbogne River is located mainly in the Swiss canton of Fribourg. The River was meandering through the plane at a very low gradient and several exceptional historic floods with large sediment accumulation are mentioned. After important river training wo ...

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 ...

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

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier

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 ...

River delta eco-morphodynamics under changing scenarios: The case of Lake Turkana, Kenya

Paolo Perona

In this work we explore the impact that changes in local climate and river hydrology have on the morphody-namics of a river delta, particularly focusing on the evolution of the delta generating at the lake inlet. We investigated the case of the delta in th ...

Biomechanics of plant anchorage at early development stage

Paolo Perona, Benoît Crouzy, 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 ...

Changes of Bioclimatic Conditions in the Klodzko Region (SW Poland)

Paolo Perona

Despite continuous technological development, lack of data or discontinuity in meteorological measurements is still an issue affecting many stations. This study was devoted to determining the bioclimatic conditions in the Klodzko region (SW Poland), where ...

Splitting probabilities and mean first-passage times across multiple thresholds of jump-and-drift transition paths

Paolo Perona, Giulio Calvani

We apply the stochastic-trajectory analysis to derive exact expressions for the mean first passage times of jump-and-drift transition paths across two or more consecutive thresholds. We perform the analysis of the crossing statistics in terms of dimensionl ...

Assessing the Weighted Usable Area for the Habitat Suitability of brown trout (Salmo trutta L.) in rivers

Giovanni De Cesare, Paolo Perona, Giulio Calvani, Francesca Padoan

To address the global loss of biodiversity in freshwater environments, understanding river habitat requirements for key species, such as brown trout (Salmo trutta L.), is crucial. The Habitat Suitability Index (HSI) aids ecologists in identifying preferred ...

Experimental quantification of hydrodynamic effects on plant cutting roots development

Yahel Eliyahu-Yakir, Junjia Kang, Paolo Perona

This paper focuses on the development of azimuthal root asymmetry in plant cuttings and related effects on the resistance to flow erosion in poorly cohesive sediment. We aim to differentiate the effects that hydrodynamic forces acting on the plant (cutting ...

On the duration of flood hydrograph using the Compound Poisson Process approximation

Paolo Perona, Giulio Calvani

River engineering projects are usually designed based on the peak discharge concept. However, some river processes depend on the shape and duration of the flow hydrograph, and their modelling is particularly relevant for designing protection and retention ...

Performance and accuracy of cross‐section tracking methods for hydromorphological habitat assessment in wadable rivers with sparse canopy conditions

Giovanni De Cesare, Paolo Perona, Robin Schroff

This article investigates the performance and accuracy of continuous Real-Time Kinematic (RTK) Global Navigation Satellite System (GNSS) position tracking for hydromorphological surveys, based on a comprehensive river restoration monitoring campaign. The a ...

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

Paolo Perona, Benoît Crouzy

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 ...
