Deep-water coastal upwelling events during wintertime in a large lake (Lake Geneva)

David Andrew Barry, Ulrich Lemmin, Andrea Cimatoribus, Rafael Sebastian Reiss

Convective winter cooling is an important process in the annual cycle of a lake ecosystem, because it brings oxygen to the deeper layers. However, in deep lakes, convective processes are often not strong enough to extend the mixing down to the deepest laye ...

Impacts 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 ...

Assessing 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 ...

Three-Dimensional Simulation of Lake Ontario North-Shore Hydrodynamics and Contaminant Transport

Damien Bouffard

The hydrodynamics and contaminant transport in the nearshore region of Lake Ontario, from Port Hope to Cobourg, were simulated. The model results were comprehensively validated against observations of water level, temperature, and currents collected during ...

3D modelling of nearshore coastal morphodynamics

David Andrew Barry, Roham Bakhtyar

Coastal 3D nearshore processes were considered with an emphasis on the effects of oceanic forcing and beach characteristics on sediment transport in both cross- and alongshore directions, as well as on foreshore bathymetry changes. In our numerical experim ...

Numerical 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 ...

Wave-induced watertable fluctuations, sediment transport and beach profile change: Modeling and comparison with large-scale laboratory experiments

David Andrew Barry, Alessandro Brovelli, Roham Bakhtyar

Coastal groundwater systems can have a considerable impact on sediment transport and foreshore evolution in the surf and swash zones. Process-based modeling of wave motion on a permeable beach taking into account wave-aquifer interactions was conducted to ...

Impacts of 3D wave and tidal forcing on nearshore hydrodynamics

David Andrew Barry, Roham Bakhtyar

Numerical investigations covering all the physical processes occurring in the surf and swash zones, including the cross-shore and longshore flows, have not been fully developed, although considerable work in 2D has appeared in recent years. However, given ...

Numerical 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 ...

Cross-shore sediment transport estimation using fuzzy inference system in the swash zone

Roham Bakhtyar

The interactions between fluid and sediment in the swash zone dominate the erosion or accretion of the beach, and they act as boundary conditions for nearshore hydrodynamic and morphodynamic models. Thus, the evaluation of sediment transport is of particul ...
