Waterborne Virus Transport and Risk Assessment in Lake Geneva Under Climate Change

Tamar Kohn, Chaojie Li

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 ...

Decadal shoreline erosion and recovery of beaches in modified and natural estuaries

Vincent Henri De Staercke

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 ...

Impacts 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 ...

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 ...

Numerical 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 ...

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 ...

Numerical simulation of two-phase flow for sediment transport in the inner-surf and swash zones

David Andrew Barry, Roham Bakhtyar

A two-dimensional two-phase flow framework for fluid- sediment flow simulation in the surf and swash zones was described. Propagation, breaking, uprush and backwash of waves on sloping beaches were studied numerically with an emphasis on fluid hydrodynamic ...

Numerical simulation of surf-swash zone motions and turbulent flow

David Andrew Barry, Roham Bakhtyar

A two-dimensional numerical model was presented for the simulation of wave breaking, runup and turbulence in the surf and swash zones. The main components of the model are the Reynolds-Averaged Navier-Stokes equations describing the average motion of a tur ...

Prediction of Longshore Sediment Transport Using Soft Computing Techniques

David Andrew Barry, Roham Bakhtyar

An important task for coastal engineers is to predict the sediment transport rates in coastal regions with correct estimation of this transport rate, it is possible to predict both natural morphological or beach morphology changes and the influence of coas ...

Tidal influence on behaviour of a coastal aquifer adjacent to a low-relief estuary

David Andrew Barry

The tidal influence on groundwater hydrodynamics, salt- water intrusion and submarine groundwater discharge from coastal/estuarine aquifers is poorly quantified for systems with a mildly sloping beach, in contrast to the case where a vertical beach face is ...
