Tectonic controls on nearshore sediment accumulation and submarine canyon morphology offshore La Jolla, Southern California

CHIRP seismic and swath bathymetry data acquired offshore La Jolla, California provide an unprecedented three-dimensional view of the La Jolla and Scripps submarine canyons. Shore-parallel patterns of tectonic deformation appear to control nearshore sedime ...

Hypolimnetic oxygen consumption by sediment-based reduced substances in former eutrophic lakes

Alfred Johny Wüest, Beat Mueller, Martin Schmid

We quantified the areal hypolimnetic mineralization rate (AHM; total areal hypolimnetic oxygen depletion including the formation of reduced substances) in two formerly eutrophic lakes based on 20 yr of water-column data collected during oligotrophication. ...

Geological characterization of cataclastic rock samples using medical X-ray computerized tomography

Pierre Guillaume Christe

Technical difficulties associated with tunnelling operations in tectonized geological settings are frequently encountered. They may include instantaneous and delayed cavity convergence, sudden collapse of walls or roof of a gallery, outpouring of fault-fil ...

One-Dimensional Numerical Modelling Of Mobile Bed Evolution In A Flume With A Side Weir

Anton Schleiss, Burkhard Rosier

Side weirs are widely used to control flow processes along a channel or river. The lateral loss of water reduces the sediment transport capacity in the main-channel leading to local sediment deposition near the overflow. The design discharge to be diverted ...

A study of the dynamics of saturated granular assemblages and its implications for transport, stress propagation and failure in marine sediments

Nicolas Le Dantec

The subject of small-scale marine sediment mechanics is an area of active research, motivated by its key role in beach and shelf processes. Much of the existing small-scale work has focused on two-phase flows and particle behavior at the sediment interface ...

Channel formation during flushing of large shallow reservoirs with different geometries

Anton Schleiss, Sameh Ahmad Kantoush

Depositional and flow patterns are first described to gain an understanding of the erosion patterns during hydraulic flushing in a reservoir. Considering the importance of this issue, two modes of flushing operation for control of sedimentation were perfor ...

Dry rock avalanche propagation

Irene Manzella

Rock avalanches are catastrophic phenomena which are not yet exhaustively understood. They consist of rock mass movements of more than one million cubic metres, involving a great amount of energy and travelling farther than expected with a normal sliding f ...

Influence of shallow reservoir geometry on the flow pattern and sedimentation process by suspended sediments

Anton Schleiss, Erik Bollaert, Sameh Ahmad Kantoush

Résumé Dans le cadre du projet de recherche sur la sédimentation de réservoirs à faible profondeur, en particulier les sédiments en suspension, les paramètres suivants ont été étudiés: l’influence de la géométrie du réservoir sur le transport des sédiments ...

Evolution of sediment deposition and flow patterns in a rectangular shallow reservoir under suspended sediment load

Anton Schleiss, Sameh Ahmad Kantoush

The deposition behavior of fine sediment is an important phenomenon, which remains unclear to engineers concerned about reservoir sedimentation. In the present case bed level changes, suspended sediment concentrations, and flow velocities were measured in ...
