Hydro-morphological processes through permeable sediment traps at mountain rivers

In alpine regions, villages are often situated near alluvial fans, which are fed by mountain rivers transporting high sediment load during floods. In the past, these mountain rivers on the alluvial fans have often been channelized near urbanized areas, whe ...

Measuring Bedload Sediment Transport with an Acoustic Doppler Velocity Profiler

Koen Blanckaert, Joris Heyman

Acoustic Doppler velocity profilers (ADVP) measure the velocity simultaneously in a linear array of bins. They have been successfully used in the past to measure three-dimensional turbulent flow and the dynamics of suspended sediment. The capability of ADV ...

Hydro-morphological processes through permeable sediment traps at mountain rivers

Sebastian Schwindt

Sediment traps are used for the protection of urban settlements at rivers in mountainous regions. These structures aim at the retention of sediment in the case of hazardous floods, but existing sediment traps tend to retain sediment also when the discharge ...

Effects of Lateral and Vertical Constrictions on Flow in Rough Steep Channels with Bedload

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastian Schwindt

Two-phase flows occurring at flow constrictions such as bridges or open sediment check dams are complex, especially for steep rivers with bedload transport. Dangerous bedload deposition and backwater effects may occur in steep mountain rivers at bridges. I ...

Stochastic bedload transport model in mountain streams.

Christophe Ancey

Describing bedload transport as a stochastic process is an idea that emerged in the 1930s with the pioneering work of Einstein. For a long time, the stochastic approach attracted marginal attention, but the situation has radically changed over the last dec ...

Bedload tranport rate fluctuations in a flume with alternate bars under steady state conditions.

Christophe Ancey, Blaise Etienne Marceau Dhont

Bedload transport rate in gravel-bed rivers under steady flow conditions shows large fluctuations (Singh et al., 2009). The development, destruction and migration of bedforms (Gomez et al., 1989; Recking et al., 2009), in combination with grain sorting (Is ...

Replenishment of sediment downstream of dams

Elena Battisacco

Dams on rivers alter the sediment continuum, trapping water and sediment in the upstream reservoirs. River reaches downstream are affected by several negative effects, such as bed incision, reduction of the river morphological variability, development of a ...

Time Scales, Bedforms and Bedload Transport

Blaise Etienne Marceau Dhont

Bedload transport rates in mountain streams may exhibit wide fluctuations even under constant flow conditions. A better understanding of bedload pulses is key to predict natural hazards induced by torrential activity and sediment issues in mountainous area ...

Tracking bed load particles in a steep flume: Methods and results.

Christophe Ancey, Joris Heyman

In this paper, we present an experimental study about the motion of bed load particles in water. Recent developments in the stochastic theory of bed load transport call for precise experimental data to validate the models. We set up the experiment in a til ...
