Hydromorphodynamic effects of the width ratio and local tributary widening on discordant confluences

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso

River training works performed in the last couple of centuries constrained the natural dynamics of channel networks in locations that include the confluences between tributaries and main channels. As a result, the dynamics of these confluences are currentl ...

Anisotropic Volumetric Response of Shales upon Suction Changes

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Anisotropic fabric and volumetric response to suction changes represent two main features of shales, which are involved in several engineering applications. However, a comprehensive understanding of the interaction between these two aspects is still missin ...

Assessment of the performance of numerical modeling in reproducing a replenishment of sediments in a water-worked channel

Anton Schleiss, Carmelo Juez Jiménez, Elena Battisacco

The artificial replenishment of sediment is used as a method to re-establish sediment continuity down- stream of a dam. However, the impact of this technique on the hydraulics conditions, and resulting bed morphology, is yet to be understood. Several numer ...

Influence of consecutive sediment replenishment on channel bed morphology

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Elena Battisacco, Lena Bösch

Dams interrupt the longitudinal connectivity of a river as they store water and trap sediment. When transport capacity downstream of dams exceeds sediment supply, water becomes hungry and channel incision, bed armouring and reduction of morphological diver ...

Exploring the physics of sediment transport in non-uniform super-critical ows using a large dataset of particle trajectories

Christophe Ancey, Joris Heyman

In this article, we present 10 experiments carried out in a steep, shallow water ume made of an erodible bed of natural, uniform gravel. We simultaneously recorded bed load particle motion, bed and water elevation using two high-speed cameras. Particle tra ...

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 ...

Bed load transport over a broad range of timescales: Determination of three regimes of fluctuations

Christophe Ancey, Joris Heyman, François Mettra, Hongbo Ma

This paper describes the relationship between the statistics of bed load transport flux and the timescale over which it is sampled. A stochastic formulation is developed for the probability distribution function of bed load transport flux, based on the Anc ...

Ripple formation and sediment-suspension events in unsteady depth-varying open-channel flow

Ulrich Lemmin, Fereshteh Bagherimiyab Hunkeler

The development of ripples and its effects on suspended sediment during unsteady flow was studied experimentally to understand and quantify the processes during floods. Quasi-instantaneous profiles of velocity and sediment concentration were taken simultan ...
