Limits between surface and inner clogging of riverbed by fine sediment
Giovanni De Cesare, Romain Maxime Dubuis
The deposition of fine sediment on top of the riverbed affects the reproduction of spawning fishes and some species of benthos. The clogging of the substrate resulting from this deposition is a well-known issue in rivers affected by anthropogenic activity ...
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 ...
2023Dynamics of Dual-Mode Bedload Transport With Three-Dimensional Alternate Bars Migration in Subcritical Flow: Experiments and Model Analysis
Mehrdad Kiani Oshtorjani, Zhipeng Li, Yong Zhang
Bedload transport often exhibits dual-mode behavior due to interactions of spatiotemporal controlling factors with the migrating three-dimensional bedforms (characterized by the fully developed patterns in the bed, such as alternate bars, pools, and cluste ...
AMER GEOPHYSICAL UNION2023Experimental Study on Bedload Transport and Bedforms: Behaviour and Interplay in Steep Turbulent Streams
In mountain regions, steep streams play an important role in water and sediment connectivity. In these highly dynamic systems, water flow features, sediment fluxes and stream morphologies are tightly interlinked over a broad range of temporal and spatial s ...
