Decadal shoreline erosion and recovery of beaches in modified and natural estuaries
Sandy beaches in estuaries and bays (BEBs) are common landforms on the coasts of many major cities. They exist under a wide range of settings and their morphology is controlled by their distance from the estuary/bay entrance, exposure to different types of ...
ELSEVIER2021A Physical Model for the Uprooting of Flexible Vegetation on River Bars
Sediment deposition and bank accretion are promoted by the establishment and growth of pioneer plant species, a direct consequence of plant survival during flood events. Similarly, the uprooting of riparian vegetation on river bars during floods can subseq ...
2019Biomorphological scaling laws from convectively accelerated streams
Paolo Perona, Giulio Calvani, Coralie Schick
Worldwide convectively accelerated streams flowing in downstream-narrowing river sections show that riverbed vegetation growing on alluvial sediment bars gradually disappears, forming a front beyond which vegetation is absent. We revise a recently proposed ...
2019Hydrodynamics of mountain-river confluences and its relationship to sediment transport
Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña
Mountain confluences are characterized by narrow and steep tributaries that provide important sediment load to the confluence, whereas themain channel supplies the dominant flow discharge. This results in a marked bed discordance between the tributary and ...
American Geophysical Union2017Impacts of wave and tidal forcing on 3D nearshore processes on natural beaches. Part I: Flow and turbulence fields
David Andrew Barry, Roham Bakhtyar
The major objective of this study was to develop further understanding of 3D nearshore hydrodynamics under a variety of wave and tidal forcing conditions. The main tool used was a comprehensive 3D numerical model – combining the flow module of Delft3D with ...
Techno-Press2016Impacts of wave and tidal forcing on 3D nearshore processes on natural beaches. Part II. Sediment transport
David Andrew Barry, Roham Bakhtyar
This is the second of two papers on the 3D numerical modeling of nearshore hydro- and morphodynamics. In Part I, the focus was on surf and swash zone hydrodynamics in the cross-shore and longshore directions. Here, we consider nearshore processes with an e ...
Techno-Press2016Assessing the Hydro-Morphodynamic Response of a Beach Protected by Detached, Impermeable, Submerged Breakwaters: A Numerical Approach
Coastal areas host a large fraction of the world's population and are exposed to natural extreme events, which are a serious threat to human life, as well as to economies. For this reason, sea storms are increasingly the object of studies, and the design o ...
Coastal Education & Research Foundation2016Flow-induced uprooting of young vegetation on river bedforms
Paolo Perona, Benoît Crouzy, 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. ...
Crc Press-Taylor & Francis Group2014Above and below-ground Salix dynamics in response to river processes
Riparian vegetation influences hydraulic and morphodynamic river processes and may contribute to sediment stabilization. In turn, vegetation recruitment and growth on non-cohesive fluvial deposits strongly depends on river hydrology and the ability of root ...
Wiley-Blackwell2014Experimental assessment of riverbed sediment reinforcement by vegetation roots
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 ...
