Influence of beach grain size and bed slope on nearshore hydro- and morpho-dynamics
David Andrew Barry, Roham Bakhtyar
Two major parameters that determine the beach type are sediment grain size and beach slope. Intermediate beaches normally have steep slopes and are associated with coarse-grained sands and narrow surf zones, while dissipative beaches generally have mild sl ...
2012Signatures of sea level changes on tidal geomorphology: Experiments on network incision and retreat
How do tidal networks respond to changes in relative mean sea level (RMSL)? The question on whether the morphological features of a tidal landscape retain signatures of past environmental forcings, or are in equilibrium with current ones, is critical to ou ...
2012Modeling of Sediment Management for the Lavey Run-of-River HPP in Switzerland
Anton Schleiss, Martin Peter Bieri, Michael Müller
Reservoir sedimentation hinders the operation of the Lavey run-of-river hydropower plant (HPP) on the Rhone River in Switzerland. Deposits upstream of the gated weir and the lateral water intake reduce the flood release capacity and entrain sediments into ...
2012Numerical experiments on breaking waves on contrasting beaches using a two-phase flow approach
David Andrew Barry, Roham Bakhtyar
A mechanistic understanding of beach environments needs to account for interactions of oceanic forcing and beach materials, in particular the role of waves on the evolution of the beach profile. A fully coupled two-phase flow model was used to simulate nea ...
Elsevier2012Etude expérimentale de refuges à poissons aménagés dans les berges de rivières soumises aux éclusées hydroélectriques
Downstream of hydroelectric storage dams, the rivers suffer from rapid, frequent and intense flow variations linked to the power production constraints. Subjected to this hydropeaking phenomenon, the fish population suffers from a known decline. In the res ...
EPFL2011Cross-shore sediment transport estimation using fuzzy inference system in the swash zone
The interactions between fluid and sediment in the swash zone dominate the erosion or accretion of the beach, and they act as boundary conditions for nearshore hydrodynamic and morphodynamic models. Thus, the evaluation of sediment transport is of particul ...
