An observation-based stochastic model for sediment and vegetation dynamics in the floodplain of an Alpine braided river

Riparian vegetation dynamics in Alpine rivers are to a large extent driven by the timing and magnitude of floods which inundate the floodplain, transport sediment, erode the river bed, and create and destroy suitable germination sites. Here we present a st ...

Deposition of sediment mixture due to jet effluent into a rectangular shallow reservoir

Anton Schleiss, Sameh Ahmad Kantoush

Shallow reservoirs are threatened by fast filling up with sediments, even if the entering sediments are only suspended loads. The sedimentation process is strongly influenced by the geometry of such shallow reservoirs. In the framework of a research projec ...

Parameter Changes from Upscaling of a Local Scale, Process-Based Erosion Model

David Andrew Barry, Seifeddine Jomaa

Soil erosion affects agricultural productivity, the natural environment and infrastructure security. Soil loss and its associated impacts are important environmental problems. Consequently, model-based predictions of erosion are beneficial for a variety of ...

Experimental study on the influence of the geometry of shallow reservoirs on flow patterns and sedimentation by suspended sediments

Sameh Ahmad Kantoush

The worst enemy of sustainable use of reservoirs is sedimentation. Often the main silting process is the result of settling down of suspended sediments. In shallow reservoirs the flow pattern and the sediment deposition processes are strongly influenced by ...

Transport of suspended sediment under the dam-break flow on an inclined plane bed of arbitrary slope

The problem of transport of suspended sediment after the break of a dam on an inclined bed is considered. To that end we use the shallow-water approximation for arbitrary, constant slopes of the bottom, taking into consideration the effect of friction. The ...

Sediment management in alpine in alpine regions

Giovanni De Cesare, Javier García Hernández, Rémi Martinerie

Sediment transport in alpine rivers is responsible for numerous problems related to reservoir sedimentation, river training works and flood protection. These different subjects are often treated locally, even if they are part of a more global solid transpo ...

Stochastic sediment-Vegetation dynamics in an Alpine braided river

Paolo Perona, Peter Molnar

We propose a stochastic modelling framework to simulate the spatially lumped sediment and vegetation dynamics in a flood plain of a braided gravel bed river as an alternative to detailed morphodynamic modelling. The idea is that floods intermittently erode ...

Near-field flow structure of a confined wall jet on flat and concave rough walls

Ulrich Lemmin, Ismail Albayrak

Experimental results are presented of the mean flow and turbulence characteristics in the near field of a plane wall jet issuing from a nozzle onto flat and concave walls consisting of fixed sand beds. This is a flow configuration of interest for sediment ...
