Particle size-segregation in granular ows driven by a conveyor belt.

Christophe Ancey, Tomás Alfredo Trewhela Palacios, Kasper van der Vaart

Particle motion within the leading edge of bidisperse gravity-driven granular flows is affected by particle size segregation. Shear-induced segregation causes coarse particles to move towards the upper layers. Then, these are advected down to the tip regio ...

Continuous Monitoring of Bed-Load Transport in a Laboratory Flume Using an Impact Sensor.

Christophe Ancey, Blaise Etienne Marceau Dhont, Gauthier Paul Daniel Marie Rousseau

Bed-load transport rate in gravel-bed rivers shows large non-Gaussian fluctuations, even under steady flow conditions. The development of high-resolution measurement techniques during the last two decades creates research opportunities to study the intermi ...

Existence and Non-uniqueness of Global Weak Solutions to Inviscid Primitive and Boussinesq Equations

Elisabetta Chiodaroli

We consider the initial value problem for the inviscid Primitive and Boussinesq equations in three spatial dimensions. We recast both systems as an abstract Euler-type system and apply the methods of convex integration of De Lellis and Sz,kelyhidi to show ...

Entrainment,motion, and deposition of coarse particles transported by water over a sloping mobile bed

Christophe Ancey, Joris Heyman

In gravel bed rivers, bed load transport exhibits considerable variability in time and space. Recently, stochastic bed load transport theories have been developed to address the mechanisms and effects of bed load transport fluctuations. Stochastic models i ...

The nature and role of advection in advection-diffusion equations used for modelling bed load transport

Christophe Ancey, Joris Heyman

The advection-diffusion equation arises quite often in the context of sediment transport, e.g., for describing time and space variations in the particle activity (the solid volume of particles in motion per unit streambed area). Stochastic models can also ...

Stochastic interpretation of the advection diffusion equation and its relevance to bed load transport

Christophe Ancey, Joris Heyman

The advection diffusion equation is one of the most widespread equations in physics. It arises quite often in the context of sediment transport, e.g., for describing time and space variations in the particle activity (the solid volume of particles in motio ...

Sediment diffusion in deterministic non-equilibrium bed load transport simulations

Christophe Ancey

The objective of this paper is to examine the importance of sediment diffusion relative to advection in bed load transport. At moderate bottom shear stress, water turbulence is too weak for picking up and keeping particles in suspension and so shallow wate ...
