Abstract The role of riparian vegetation in shaping river morphology is widely recognized. interaction between growth and riverbed evolution characterized by complex nonlinear feedbacks, which hinder direct estimates the key elements on morphological evolutionary trajectories gravel bed rivers. Adopting a simple theoretical framework, we develop numerical model couples hydromorphodynamics with biomass dynamics. We perform sensitivity analysis considering several parameters as flood...
Abstract Deterioration of salt marshes may be due to several factors related increased anthropic pressure, sea level rise, and erosive processes. While can reach equilibrium in the vertical direction, adapting they are inherently unstable horizontal direction. Marsh boundaries characterized by scarps with bare sediment below vegetated surface layer that easily removed wave‐induced erosion. In this work, we explore different mechanisms involved erosion marsh borders through interpretation...
Transport processes of plastic particles in freshwater and marine environments are one the relevant advances knowledge predicting fate environment. Here, we investigated effect different shapes on settling velocity, finding a representative reference diameter which encompasses three-dimensional like pellets or spherules, two-dimensional fragments disks, one-dimensional filaments fibers. The new method is able to predict velocity natural given size Corey shape factor coefficient, over entire...

The results two are compared with measurements collected during an experimental campaign conducted colonized Common reed (Phragmites australis (Cav.) Trin. ex Steud.). Experimental vegetative Chézy’s coefficients have been retrieved from analysis instantaneous velocity measurements,...
ABSTRACT In natural gravel‐bed streams, the complex topography of bed can cause variation flow resistance and sediment transport. Previous studies have shown that in addition to grain (skin friction), is also caused by bank roughness, channel bars, undulations curvature. Sediment transport similarly influenced topography, rate vary spatially. A three‐dimensional (3D) numerical model was used generate a detailed description bedload fields rivers. Here we quantify reach‐averaged hydraulic...
Salt marshes are delicate ecosystems which disappearing in many areas of the world, mainly due to increasing rates sea level rise, subsidence, and anthropic pressure. The lateral erosion edge salt is one most important processes determining changes morphology, wind waves have a key role this retreat. Lateral retreat occurs by means several types mass failure processes, typically cantilever, sliding, toppling. In literature, no mechanistic models for description toppling available. study, we...
Several studies focused on the role of rivers as vectors microplastics (MPs) towards sea. It is well known that during their path through fluvial environment, MPs interact with riverbed sediments; however, main factors impacting mobility within upper part hyporheic zone are not clear yet. The present work investigates different sediment size layers in affecting most common MP (Polyethylene terephthalate - PET spheres, 3D-ellipsoids, polystyrene PS fragments and polyamide PA fibers) porous...
Bed-load transport is commonly evaluated in the condition of a hydrostatic pressure distribution flow field; while this reasonable for quasi-steady, quasi-uniform rectilinear flows, it cannot be satisfied large variety conditions, i.e., near an obstacle as case bridge pier. The dimensionless Shields number, which contains assumption its denominator, therefore strictly applied to evaluate bed-load all configurations where nonhydrostatic distributions are observed. In present work,...
Predicting the equilibrium cross section of natural rivers has been widely investigated in fluvial morphology. Several approaches have developed to meet this aim, starting from regime equations empirical formulations Parker et al. (2007) and Wilkerson (2011), who proposed quasi‐universal relations for describing bankfull conditions sand gravel bed rivers. Nevertheless, a general physics‐based framework is still missing, it remains an open issue better clarify basic mechanisms whereby river...
The primary cause of many bridge collapses is related to hydraulic issues, and the Italian technical standards for constructions (NTC 2018) offer limited guidance on design verification criteria bridges, especially concerning river processes. Recognizing this gap, a working group dedicated “Hydraulic Compatibility Bridges” (sites.google.com/view/gii-ponti) was established in 2021. group's objective develop proposals good practices guidelines that assess compatibility, providing foundation...
Abstract Recent studies have shown that vegetation can trigger sediment resuspension and facilitate movement, highlighting the possibility of finding a linkage between turbulence transport rates in vegetated areas. This study investigates flow hydrodynamics, through double‐averaged analysis, focusing on data were acquired experiments with dunes leafy flexible characterized by different Leaf Area Indices (LAI), which denotes total one‐sided leaf area per unit ground (). Flow velocity was...
The widespread distribution of microplastics (MP) in aquatic systems highlights the need for a clear understanding how they are transported and accumulate on bottom water bodies. Developing predictive models MP dispersion, sedimentation, bioaccumulation is crucial informing regulatory decisions mitigating impact related pollutants. Among key parameters, settling velocity considered most critical predicting their behavior environments. Recent studies suggest an intricate not fully understood...
ABSTRACT In the last few years, vegetated rivers have been managed with main purpose of achieving water drainage and improving conveyance through vegetation removal. However, this leads to peak discharge augmentation wave travel time reduction. This study assesses shredding selective cut impacts on flood risk management. Flow resistance was obtained considering morphology hydrodynamic measurements performed during two field campaigns conducted just before destructive in growing season after...
Sediment deposition and bank accretion are promoted by the establishment growth of pioneer plant species, a direct consequence survival during flood events. Similarly, uprooting riparian vegetation on river bars floods can subsequently alter hydraulics, sediment dynamics, bar evolution. In this work, we focus removal flexible seedlings due to both hydraulic forces bed erosion, specifically examining failure mechanisms associated with root pull‐out. We provide conceptual model new physical...
Abstract The development of sustainable river management strategies requires knowledge the effect vegetation on hydrodynamics and sediment transport. To date, complex physical processes involving combined effects leafy flexible mobile bedforms are not completely understood. Most transport models have been developed for bare bed conditions so that their performance in presence remains unclear. On other hand, recently consider vegetated but they typically account only rigid cylinders some...
