Influence of geometry shape factor on trapping and flushing efficiencies

The trap efficiency of a shallow reservoir depends on the characteristics of the inflowing sediments and the retention time of the water in the reservoir, which in turn are controlled by the reservoir geometry. With the purpose of controlling the trapped a ...

Spatial patterns of aeolian sediment deposition in vegetation canopies: observations from wind tunnel experiments using colored sand

Katherine Colby Leonard

In environments affected by wind erosion, plants act as traps for aeolian sediment, which leads to a small-scale mosaic of depositional and erosional sediment transport regimes. This wind tunnel study used colored sand to visualize spatial patterns of sedi ...

Coupling between flow and sediment deposition in rectangular shallow reservoirs

Anton Schleiss, Erica Camnasio, Michel Pirotton

Flow velocity and sedimentation patterns were investigated experimentally and numerically in shallow rectangular reservoirs with different asymmetric locations of the inlet and outlet channels. Velocity fields were measured in the entire reservoir, both fo ...

The Hairsine-Rose Soil Erosion Model: Analysis for Total Sediment Concentration

David Andrew Barry, Seifeddine Jomaa

The Hairsine-Rose (HR) model considers rainfall- and shear-driven erosion of the soil bed, overland transport and sediment deposition. Here, we consider the model for rainfall-driven erosion. The model takes account of the different erodabilities of the or ...

Sedimentological processes in the Rhone Delta subaquatic canyons (France-Switzerland)

Nicolas Le Dantec

Deltas are very sensitive environments and highly vulnerable to variations in water discharge and the amount of suspended sediment load provided by the delta-forming currents. Human activities in the watershed, such as building of dams and irrigation ditch ...

Sedimentary processes and triggering mechanisms of debris flows in subaquatic canyons in Rhone delta (Lake Geneva, Switzerland, France)

Nicolas Le Dantec

Subaquatic canyons in deltas are major pathways for the transport of particles from land to the deep basins. They represent active environments with frequent deltaic failures and mass-movement deposits potentially leading to hazardous (tsunami waves) and e ...

Geological, geomorphological, facies and allostratigraphic maps of the Eberswalde fan delta

Geological, facies, geomorphological and allostratigraphic map of the Eberswalde fan delta area are presented. The Eberswalde fan delta is proposed as a sort of prototype area to map sedimentary deposits, because of its excellent data coverage and its vari ...

Flow and sediment dynamics in bed discordant channel confluences

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro

Confluences between small steep tributaries with dominant supply of poorly sorted sediment and larger main channels with dominant flow supply, which are characterized by a pronounced bed discordance, have not yet been considered in the literature. The hydr ...

Multi-robot olfactory search in structured environments

Ali Marjovi

This paper presents a cooperative distributed approach for searching odor sources in unknown structured environments with multiple mobile robots. While searching and exploring the environment, the robots independently generate on-line local topological map ...

Complémentarité de la modélisation physique et numérique à l’exemple d’un aménagement hydroélectrique / Complementarity of physical and numerical modeling using the example of a run-of-river hydropower plant

Martin Peter Bieri, Michael Müller

Comme beaucoup d’aménagements hydroélectriques au fil de l’eau, celui de Lavey sur le Rhône en Suisse est affecté de manière récurrente par l’alluvionnement de sa retenue. Outre la gestion sédimentaire, les thèmes abordés par la modélisation concernent éga ...
