Influence of the shear stress on fine sediment exchanges with the substrate using UVP measurements
Giovanni De Cesare, Romain Maxime Dubuis
The dynamic of fine sediment in rivers is closely related to the interactions between fine particles, the riverbed and the flow conditions. The accumulation of fine sediment in the riverbed reduces vertical water exchanges and can have detrimental effects ...
2023The clogging of riverbeds: A review of the physical processes
Giovanni De Cesare, Romain Maxime Dubuis
Fine sediment represents an important part of the solid flux of rivers. Due to the size of these particles, they are often transported as suspended load. They gradually fill the pores of the substrate forming the hyporheic zone or cover the substrate by se ...
2023Clogging of riverbed substrates by fine sediment
Riverbeds represent the habitat of numerous aquatic species. Exchanges between the groundwater, the hyporheic zone and the surface flow are also essential for river ecosystems. Fine sediment transported by rivers deposits inside or on top of the bed and mo ...
EPFL2023Reduction of riverbed clogging related to sediment flushing
Giovanni De Cesare, Romain Maxime Dubuis
The ecological effects of dams on sediment and river flow have been subject to an increasing attention, leading to the implementation of mitigation measures such as environmental flow release and sediment replenishment. However, fine sediment dynamics have ...
CRC Press/Balkema2023p Spatio-temporal deposition profile of an experimentally produced turbidity current with a continuous suspension supply
Giovanni De Cesare, Shun Nomura
A turbidity current is a turbulent, particle-laden gravity current that is driven by density differences resulting from the presence of suspended sediment particles. The current travels downslope, bearing a large amount of sediment over a great distance, a ...
IRTCES2022Parameterizing snow saltation: the exponential decay of the mass flux profile and its relation to the saltation dynamics
Varun Sharma, Michael Lehning, Daniela Brito Melo, Armin Sigmund
Drifting snow events lead to snow redistribution and enhance snow sublimation. Taking into account the importance of snow sublimation to the correct prediction of the surface mass balance, a general consensus has emerged within the scientific community on ...
