Experimental quantification of hydrodynamic effects on plant cutting roots development

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 ...

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 ...

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 ...

Mean hydrograph event from exact ensemble averages of stochastic trajectories

Paolo Perona, Giulio Calvani

The design of hydraulic structures, flood protection systems, and river management strategies often relies on the peak-flow discharge associated with a specific return period. However, many river processes are related to the shape and duration of the entir ...

Uncertainty analysis of field trials of low-cost Bi-TiO_2 -P25 solar photocatalyst for sustainable water treatment

Paolo Perona, Giulio Calvani

Solar photocatalysis has the potential to reduce chemical and microbial contaminants in water and make it safer for consumption in an effective and sustainable manner. This has been studied and proven well under laboratoryscale conditions. In our previous ...

Mapping groundwater-related flooding in urban coastal regions

Paolo Perona, Emmanuel Qays Dubois, Montana Marshall

Coastal urban environments are facing an increasing risk of flooding from both surface water and groundwater due to globally elevated water levels, causing substantial socio-economic damages, threatening livelihoods, and hindering economic development. To ...

Stochastic optimization to maximize water supply index in conjunctive use of surface and groundwater

David Andrew Barry, Paolo Perona

Systematic operation of water resources systems requires rules that consider the uncertainties affecting system performance. Here, stochastic dynamic programming (SDP) is used to structure and solve a full-scale surface and groundwater conjunctive use mode ...

Hydraulic drive framework on habitat suitability enhances movement bias of brown trout in stream networks

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

Freshwater ecosystems face increasing threats from human activities and climate change, thus requiring efforts to reduce impacts and prevent further deterioration. Restoration projects for riverine environments often rely on hydraulic, habitat, and metapop ...

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 ...

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 ...
