Physical Modeling of Sediment Trap for Le Bez River, Switzerland

Giovanni De Cesare, Azin Amini, Romain Nathan Hippolyte Merlin Van Mol, Najla Schaller

The Le Bez torrent in the Canton of Bern, Switzerland, is known for flashy and violent floods due to its watershed topography and vegetation conditions. Such floods can bring a substantial amount of sediment and wood into the small downstream village of Vi ...

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 ...

Wind Tunnel Studies of Shear Stress Partitioning in Live Plant Canopies

Benjamin Andreas Walter

The earth's surface is permanently exposed to the atmosphere and accordingly to strong wind forces in many regions. Aerodynamic entrainment, transport and redeposition of sand, soil or snow are able to considerably reshape the surface morphology and influe ...

Shear-Stress Partitioning in Live Plant Canopies and Modifications to Raupach's Model

Michael Lehning, Benjamin Andreas Walter

The spatial peak surface shear stress on the ground beneath vegetation canopies is responsible for the onset of particle entrainment and its precise and accurate prediction is essential when modelling soil, snow or sand erosion. This study investigates she ...

Mathematical modelling for the evolution of aeolian dunes formed by a mixture of sands: entrainment-deposition formulation

Fabio Nobile, Luca Formaggia

In this work we present a mathematical model of the evolution of aeolian sand dunes, in particular we consider the case of dunes formed by a mixture of sands with different characteristics. We first recall a basic model for the evolution of two dimensional ...

Drift stabilization of ballooning modes in an inward-Shifted LHD configuration

Jonathan Graves, Wilfred Anthony Cooper, Lucie Brocher

A drift-magnetohydrodynamic theory is applied to a background anisotropic pressure equilibrium state to generate a drift corrected ballooning mode equation. The ratio of the mode frequency to the hot particle drift frequency constitutes the critical expans ...

Impacts Of Sand Transport On Flow Variables And Dissolved Oxygen In Gravel-Bed Streams Suitable For Salmonid Spawning

Mário Jorge Rodrigues Pereira Da Franca, Ana Margarida Da Costa Ricardo

Increased sediment production resulting from the erosion of unprotected soil in a catchment may result in severe changes in the morphodynamics and hydrodynamics of mountain rivers. Sediment overfeeding can lead to the degradation of salmonids' spawning sit ...

Drift stabilization of ballooning modes in a high-$\langle \beta \rangle$ LHD configuration

Jonathan Graves, Wilfred Anthony Cooper, Lucie Brocher

Ideal MHD yields at best inconclusive predictions about the stability of the LHD heliotron for

\langle \beta \rangle \geq 3\%

. We investigate the impact of the drift stabilization of ballooning modes for the inward shifted LHD configuration (vacuum magne ...

The effect of migrating dune forms on the flow field of an alluviral river

Koen Blanckaert

The bed of an alluvial river is highly susceptible to changes during the course of its existence. Besides variations of the large scale topography and plan form of the river, smaller scale dune forms can be observed. These recurring dune forms migrate on t ...

Efficiency of Brushwood fences in shore protection against wind-wave induced erosion

Selim Sayah

Shore protection in confined water bodies is of major importance in Switzerland where many lakes suffer severe shore erosion. It occurs mainly in shallow zones due to several reasons such as: the fluctuations of the water level , the wind-wave impact durin ...
