Ultrasonic sediment flux profiling with ACVP Technology: application to sediment-laden Boundary Layer flows
Giovanni De Cesare, David Hurther
Sediment transport in geophysical boundary layer flows has relevance to a broad spectrum of sciences ranging from the physical and chemical, to the biological, ecological and geological. Advances in sediment transport modelling and prediction strongly suff ...
2023Experimental modeling of fine sediment routing: SEDMIX device with thrusters
Giovanni De Cesare, Azin Amini, Montana Marshall
Reservoir sedimentation is a key challenge for storage sustainability because it causes volume loss, affecting hydropower production capacity, dam safety, and flood management. A preliminary EPFL study proposed and studied an innovative device (called SEDM ...
CRC Press/Balkema2023Quasi-stationary flow structure in turbidity currents
Giovanni De Cesare, Shun Nomura
A turbidity current is a particle-laden current driven by density differences due to suspended sediment particles. Turbidity currents can transport large amounts of sediment down slopes over great distances, and play a significant role in fluvial, lake and ...
IRTCES2020Field characterization of the negatively buoyant inflow of the Rhône River into Lake Geneva
David Andrew Barry, Ulrich Lemmin, Koen Blanckaert
River inflows have a major influence on lake and reservoir water quality through their input of momentum, heat, oxygen, sediment, nutrients and contaminants. The fate of these components is controlled by the hydrodynamic processes at the interface between ...
2020Sediment flushing downstream dams: a study on the clogging by fine sediments
Giovanni De Cesare, Christophe Ancey, Romain Maxime Dubuis
Water reservoirs used to produce electricity have an impact on the environment and durability by : • stopping the natural sediment flux • changing the flow regime downstream of the reservoirs • storing (fine) sediments that reduce the storage volume Those ...
2019A Physical Model for the Uprooting of Flexible Vegetation on River Bars
Sediment deposition and bank accretion are promoted by the establishment and growth of pioneer plant species, a direct consequence of plant survival during flood events. Similarly, the uprooting of riparian vegetation on river bars during floods can subseq ...
2019Geomorphic work by gravity currents with varying initial conditions
Gravity currents are density-driven flows that are able to transport high amounts of sediment and are responsible of great geomorphic changes. Moreover they can have severe repercussions on the environment since they are conveyors of substances, e.g. pollu ...
