Hydrodynamics of mountain-river confluences and its relationship to sediment transport

Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña

Mountain confluences are characterized by narrow and steep tributaries that provide important sediment load to the confluence, whereas themain channel supplies the dominant flow discharge. This results in a marked bed discordance between the tributary and ...

Experiments on the effect of inflow and outflow sequences on suspended sediment exchange rates

Anton Schleiss, Giovanni De Cesare, Michael Müller

In laboratory experiments, the influence of inflow and outflow sequences on the behavior of fine sediment was investigated. The experimental set-up consisted of two interconnected rectangular basins, between which water was moved back and forth. Suspended ...

Prediction and forecast of Suspended Sediment Concentration (SSC) on the Upper Yangtze basin

Mário Jorge Rodrigues Pereira Da Franca, José Pedro Gamito de Saldanha Calado Matos

Sediment transport in suspension may represent 90% or more of the global annual flux of sediment. For instance, more than 99% of the sediment supplied to the sea by the Yangtze River is suspended load. Suspended load is an important component for understan ...

Impacts of wave and tidal forcing on 3D nearshore processes on natural beaches. Part II. Sediment transport

David Andrew Barry, Roham Bakhtyar

This is the second of two papers on the 3D numerical modeling of nearshore hydro- and morphodynamics. In Part I, the focus was on surf and swash zone hydrodynamics in the cross-shore and longshore directions. Here, we consider nearshore processes with an e ...

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 ...

Bedform migration in steep channels: from local avalanches to large scale changes.

Christophe Ancey, Joris Heyman, François Mettra

Many studies have emphasized the strength of bedload transport fluctuations in steep streams, especially at low and intermediate transport conditions (relative to the threshold of incipient motion). The origins of these fluctuations, which appear on a wide ...

From bedform evolution to channel slope fluctuations in steep-slope streams.

Christophe Ancey, Joris Heyman, François Mettra, Hongbo Ma

In mountain streams, bedload transport rates are prone to strong variability. Indeed an increasing number of laboratory and field studies in steep-slope conditions show fluctuations of bedload transport rate over several temporal and spatial scales. This b ...

Fine sediment dynamics in unsteady open-channel flow studied with acoustic and optical systems

Ulrich Lemmin, Fereshteh Bagherimiyab Hunkeler

In order to simulate fine sediment dynamics over an armored bed in a tidal river, unsteady accelerating, then steady open-channel flow over a movable (but not moving) coarse gravel bed (D-50=5.5 mm) was studied. A layer of fine sediment (D-50=120 mu m) was ...
