The study of river‐riparian vegetation interactions is an important and intriguing research field in geophysics. Vegetation active element the ecological dynamics a floodplain which interacts with fluvial processes affects flow field, sediment transport, morphology river. In turn, river provides water, sediments, nutrients, seeds to nearby riparian vegetation, depending on hydrological, hydraulic, geomorphological characteristic stream. past, this complex theme was approached two different...
We review the importance of physical mechanisms involved in river meandering by comparing some existing linear models and extensions thereof. Such are hierarchically derived from a common general mathematical framework then analyzed with detailed discussion processes relevant hypotheses that involved. Experiments field data also used to discuss related morphodynamic processes. The analysis shows closure secondary currents especially modeling eddy viscosity. This aspect confirms usefulness...
A model for the evaluation of intra‐meander hyporheic exchange fluxes is presented. The method relies on a physically‐based morphodynamic to predict characteristics flow field in meandering river and temporal evolution its planimetry. induced at meander scale by sinuosity can therefore be computed. application simulated case has shown fundamental role planimetry pattern scale, influence long‐term exchange.
A river and its surrounding riparian vegetation are two dynamical systems that interact through several hydrological, geomorphological, ecological processes. This work focuses on the role played by meandering morphodynamics: River planform evolution forces dynamics, which, in turn, affect mechanical characteristics of banks influence dynamics itself. It follows despite fact a traditional engineering approach considers as static element study morphodynamics should be coupled with evolution....
Abstract Floodplains include unique environments shaped over a long time horizon along rivers and smaller streams formed by alluvial sediments. As floodplains are flat, often with highly fertile well‐accessible land, they have become the intrinsic focus of human society—while providing variety goods ecosystem services. Intensive land use is degrading their natural values significantly reducing functions A significant part these key services related ability to retain water nutrients, which...
In spite of notable advances in the description river morphodynamics, long‐term dynamics meandering rivers is still an open question, particular, regarding existence a possible statistical steady state and its scaling properties induced by competing action cutoffs reach elongation. By means extensive numerical simulations, using three fluid dynamic models different complexity analysis real data from Amazon, North America, Russia, we show that cutoffs, besides providing stability...
Riparian vegetation is part of one the most diverse and fragile ecotones. The key role played by river discharge on dynamics riparian has been widely studied documented. However, although randomness a fundamental characteristic hydrology, very few quantitative studies take into account random nature discharge. Here we propose stochastic model ecosystem forced variations in solved, analytical expressions probability density function overall biomass its first moments are obtained. These...
The occurrence of cutoff events, although sporadic, is a key component in the complex dynamics meandering rivers. In present work, we show that has twofold role: (1) It removes older meanders, limiting planform geometrical complexity (geometrical role), and (2) it generates an intermittent noise able to influence spatiotemporal whole river (dynamical role). role limits spatial evolution sporadically eliminating portions planimetry. this way stabilizes mean geometry around statistically...
Nowadays, LiDAR is widely used for individual tree detection, usually providing higher accuracy in coniferous stands than deciduous ones, where the rounded-crown, presence of understory vegetation, and random spatial distribution may affect identification algorithms. In this work, we propose a novel algorithm that aims to overcome these difficulties yield coordinates height trees on basis point density features input cloud. The was tested twelve areas, assessing its performance both...
Abstract Riparian zones are the paragon of transitional ecosystems, providing critical habitat and ecosystem services that especially threatened by global change. Following consultation with experts, 10 key challenges were identified to be addressed for riparian vegetation science management improvement: (1) Create a distinct scientific community establishing stronger bridges between disciplines; (2) Make more visible appreciated in society policies; (3) Improve knowledge regarding...
Abstract In recent decades, fluvial geomorphology and ecohydraulic research have extensively used field observations, remote sensing or hydrodynamic modelling to understand river systems. This study presents an innovative approach that combines surveys, Light Detection Ranging (LiDAR)‐based topographical biomass analyses model‐derived hydro‐morphodynamic geostatistics examine short‐term biogeomorphological changes in the wandering gravel‐bed Orco River Italy. Our primary hypothesis is...
Several geomorphological fluvial features are able to induce hyporheic exchange between the rivers and alluvial sediments. However, while small‐scale induced by bed forms has been thoroughly investigated, role of larger remains poorly understood. Here, we focus on flows driven channel sinuosity in intrameander zone. A physically based model is adopted simulate morphodynamic evolution three different meandering rivers, from first stages meander until incipient cutoff. For each stage,...
The hierarchy of channel networks in landscapes displays features that are characteristic nonequilibrium complex systems. Here we show a sequence increasingly ridge and valley is produced by system partial differential equations coupling landscape evolution dynamics with specific catchment area equation. By means linear stability analysis identify the critical conditions triggering formation emergence spacing. ensuing channelization cascade, described dimensionless number accounting for...
Abstract Vegetation is crucial for stabilizing and developing coastal dunes. Different plant species exhibit different spatial distributions which reflect their environmental role adaptation strategy. This study aims to provide a fine‐scale species‐by‐species analysis of vegetation patterns on dunes within the San Rossore–Migliarino–Massacciuccoli Regional Park (Tuscany, Italy). A comprehensive data set generated by an Object‐Based Image Analysis (OBIA) algorithm applied high‐resolution...
Glacier-climate models are crucial for understanding and predicting climate change impacts on snow glacier-fed regions. However, their accuracy depends heavily the quality of input data. While general circulation (GCMs) provide broad-scale insights, coarse spatial resolution limits ability to capture fine-scale climatic variability, especially in complex mountainous We integrate high-resolution Regional Climate Models (RCMs) Convection-Permitting (CPMs) into a glacier-climate coupled model...
An important consequence of the rapid retreat Alpine glaciers associated with global warming is increasing extent proglacial areas. These environments are dominated by a heterogeneous and dynamic fluvial system, whose evolution mostly depends on interplay between varying water discharge coarse sediment supply coming from glacier terminus. Although understanding impact bedload yield essential for preservation high-mountain regions, long-lasting investigations processes occurring in areas...
Conditions for vegetation spreading and pattern formation are mathematically framed through an analysis encompassing three fundamental processes: flow stochasticity, dynamics, sediment transport. Flow unsteadiness is included Poisson stochastic processes whereby dynamics appears as a secondary instability, which addressed by Floquet theory. Results show that the model captures physical conditions heralding transition between bare vegetated fluvial states where nonlinear growth of finite...
The present work investigates how the dynamics of meandering rivers influence formation riparian vegetation patterns. To this aim, a model coupling river and evolution was developed. Meandering were simulated with fluid dynamical using shallow water equations on an erodible bed. takes into account some main actions caused by river, i.e., table oscillations, floods, sedimentation. A logistic law exponential decay used to increase decrease in biomass, respectively, consequent migration....
The arterial tree exhibits a complex spatio-temporal wave pattern, whose healthy behaviour depends on subtle balance between mechanical and geometrical properties. Several clinical studies demonstrated that such progressively breaks down during ageing, when the aorta stiffens remodels by increasing its diameter. These two degenerative processes however, have different impacts pattern. They both tend to compensate for each other, thus reducing detrimental effect they would had if arisen...
