Using the raindrop size distribution to quantify the soil detachment rate at the laboratory scale

David Andrew Barry, Alexis Berne, Seifeddine Jomaa, Joël Jaffrain

Rainfall simulators are beneficial tools for studying soil erosion processes and sediment transport for different circumstances and scales. They are useful to better understand soil erosion mechanisms and, therefore, to develop and validate process-based e ...

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 ...

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 ...

Effect of stone coverage on soil erosion

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

Soil surface coverage has a significant impact on water infiltration, runoff and soil erosion yields. In particular, surface stones protect the soils from raindrop detachment, they retard the overland flow therefore decreasing its sediment transport capaci ...

Large-eddy simulation of a curved open-channel flow over topography

Koen Blanckaert

Large-eddy simulation LES is performed of a curved open-channel flow over topography based on the laboratory experiment by Blanckaert _“Topographic steering, flow circulation, velocity redistribution and bed topography in sharp meander bends,” Water Reso ...

Cross-comparison of meteorological and avalanche data for characterising avalanche cycles: The example of December 2008 in the eastern part of the French Alps

Johan Alexandre Philippe Gaume

In December 2008, an intense avalanche cycle occurred in the eastern part of the southern French Alps. Southerly atmospheric fluxes that progressively evolved into an easterly return caused important snowfalls with return periods up to 10 years. Cold tempe ...

Process-based model for nearshore hydrodynamics, sediment transport and morphological evolution in the surf and swash zones

David Andrew Barry, Roham Bakhtyar

Nearshore hydrodynamics and sediment transport in the nearshore zone were modeled numerically taking into account turbulent unsteady flow. The flow field was computed using the Reynolds Av-eraged Navier-Stokes equations with a k-ε turbulence closure model, ...

One-Dimensional Numerical Modelling Of Mobile Bed Evolution In A Flume With A Side Weir

Anton Schleiss, Burkhard Rosier

Side weirs are widely used to control flow processes along a channel or river. The lateral loss of water reduces the sediment transport capacity in the main-channel leading to local sediment deposition near the overflow. The design discharge to be diverted ...

Euler–Euler coupled two-phase flow modeling of sheet flow sediment motion in the nearshore

David Andrew Barry, Roham Bakhtyar

A two-dimensional numerical model was presented for the simulation of sediment transport under oscillatory sheet flow conditions in the nearshre zone. Most existing mathematical models for predicting sediment transport in this area are based on the governi ...

Two-phase hydrodynamic and sediment transport modeling of wave-generated sheet flow

David Andrew Barry, Roham Bakhtyar

This numerical investigation was carried out to advance mechanistic understanding of sediment transport under sheet flow conditions. An Euler-Euler coupled two-phase flow model was developed to simulate fluid-sediment oscillatory sheet flow. Since the conc ...
