Sediment traps with guiding channel and hybrid check dams improve controlled sediment retention
Mário Jorge Rodrigues Pereira Da Franca, Sebastian Schwindt, Stefano Tugulu, Alessandro Reffo
Sediment traps with partially open check dams are crucial elements for flood protection in alpine regions. The trapping of sediment is necessary when intense sediment transport occurs during floods that may endanger urban areas at downstream river reaches. ...
2018Design optimization of permeable sediment traps for fluvial bed load transport
Anton Schleiss, Sebastian Schwindt, Mona Jafarnejad Chaghooshi, Anita Hélène Roth
Sediment traps are crucial elements for flood protection in mountain rivers with high sediment transport capacity. Existing structures often interrupt the channel connectivity. Ideally, a sediment trap should be permeable for bed load during non-hazardous ...
2018Hydro-morphological processes through permeable sediment traps at mountain rivers
Sediment traps are used for the protection of urban settlements at rivers in mountainous regions. These structures aim at the retention of sediment in the case of hazardous floods, but existing sediment traps tend to retain sediment also when the discharge ...
EPFL2017Hydro-morphological processes through permeable sediment traps at mountain rivers
In alpine regions, villages are often situated near alluvial fans, which are fed by mountain rivers transporting high sediment load during floods. In the past, these mountain rivers on the alluvial fans have often been channelized near urbanized areas, whe ...
EPFL-LCH2017Hydromorphodynamic effects of the width ratio and local tributary widening on discordant confluences
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso
River training works performed in the last couple of centuries constrained the natural dynamics of channel networks in locations that include the confluences between tributaries and main channels. As a result, the dynamics of these confluences are currentl ...
Gfg2017Hydro-morphodynamics of open-channel confluences with low discharge ratio and dominant tributary sediment supply
River confluences in which the tributary supplies the dominant sediment load, and the flow discharge is abundantly provided by the main river, are typically observed in mountain-river basins. The existent knowledge on the hydrodynamic, morphodynamic and se ...
EPFL2015Tectonic 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 ...
Elsevier2010Modeling Of Salt Tectonics
In this work a general framework for the simulation of sedimentary basins in presence of salt structures is addressed. Sediments and evaporites are modeled as non-Newtonian fluids and the thermal effects induced by the presence of salt are taken into accou ...
2007Calculation of geological uncertainties associated with 3-D geological models
3-D geological models are built with data collected in the field such as boreholes, geophysical measurements, pilot shafts or geological mapping. Unfortunately, these data are always limited in number. It implies that geological information is sparse and s ...
