Waterborne Virus Transport and Risk Assessment in Lake Geneva Under Climate Change
Climate changes influence lake hydrodynamics and radiation levels and thus may affect the fate and transport of waterborne pathogens in lakes. This study examines the impact of climate change on the fate, transport, and associated risks of four waterborne ...
2024Decadal 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 ...
ELSEVIER2021Monthly to decadal evolution of sandy beaches in the Pittwater estuary
Even if the total length of shorelines in low-wave environments like bays, sounds, lagoons and estuaries greatly exceed that of open-ocean coasts, the morphodynamics of such systems are poorly understood. Only few studies developed models to predict change ...
2018Impacts 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-Press2016Types and concentration of microplastics found on remote island beaches during the Race for Water Odyssey
Luiz Felippe De Alencastro, Florian Faure, Frédéric Sciacca, Clément Levasseur
Initiated in 2015 by the Race for Water Foundation,
the Race for Water Odyssey is an environmental expedition which sailed across Atlantic, Pacific & Indian Oceans. It has 3 main goals: i) analyse plastic pollution on beaches of remote islands; ii) raise a ...
2016Influence of beach grain size and bed slope on nearshore hydro- and morpho-dynamics
David Andrew Barry, Roham Bakhtyar
Two major parameters that determine the beach type are sediment grain size and beach slope. Intermediate beaches normally have steep slopes and are associated with coarse-grained sands and narrow surf zones, while dissipative beaches generally have mild sl ...
2012Numerical experiments on breaking waves on contrasting beaches using a two-phase flow approach
David Andrew Barry, Roham Bakhtyar
A mechanistic understanding of beach environments needs to account for interactions of oceanic forcing and beach materials, in particular the role of waves on the evolution of the beach profile. A fully coupled two-phase flow model was used to simulate nea ...
Elsevier2012Numerical experiments on interactions between wave motion and variable-density coastal aquifers
David Andrew Barry, Alessandro Brovelli, Roham Bakhtyar
A comprehensive two-dimensional (cross-shore) process-based numerical model of nearshore hydrodynamics (based on the Navier-Stokes equations, k-ε turbulence closure and the Volume-Of-Fluid method), beach morphology, and variable-density groundwater flow (S ...
Elsevier2012Numerical experiments of breaking waves on dissipative and intermediate beaches using a two-phase flow method
David Andrew Barry, Roham Bakhtyar
A fully coupled two-phase flow model was developed to simulate nearshore fluid-sediment turbulent flow. It includes the Reynolds-Averaged Navier-Stokes equations and turbu¬lent stress closures for each phase, and accounts for inter-granular stresses. It wa ...
2011Influence of Tributary Widening on Confluence Morphodynamics
In alpine regions of Europe, river training works were typically the reason for the transformation of wide and braided rivers into linear river systems with a lack of structural diversity, i.e. gravel banks, islands, woody debris, riffles or pools. These i ...
