Simulation of fine sediment deposition on floodplains
Giovanni De Cesare, Carmelo Juez Jiménez
Rivers extend beyond the channels that are typically associated with this word. Of particular interest are flood plains, where important hydro- and morphodynamic processes occur as a result of recurrent flooding. Ecologically, they also support the establi ...
2023Exploring the efficacy of reservoir fine sediment management measures through numerical simulations
Giovanni De Cesare, Azin Amini, Samuel Luke Vorlet, Montana Marshall
Reservoir sedimentation is one of the main challenges in the sustainable operation of large reservoirs because it causes volume loss, affecting hydropower production capacity, dam safety, and flood management. To ensure the sustainability of deep reservoir ...
CRC Press/Balkema2023Reduction 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 ...
IRTCES2022Return period of vegetation uprooting by flow
Fluvial environments are dynamic systems whose evolution and management are strongly affected by the resilience of riparian vegetation to uprooting by flow. Similarly to other natural phenomena, the interactions between flow, sediment and vegetation uproot ...
2019Bottom slope influence on flow and bedload transfer through contractions
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastian Schwindt
In-stream open check dams are essential for flood protection at mountain rivers that are characterized by steep slopes (>1%) and sediment-laden flood discharges. These structures comprise an opening acting as a lateral or vertical flow contraction to force ...
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 ...
2019Adaptive locomotion of artificial microswimmers
Mahmut Selman Sakar, Fazil Emre Uslu
Bacteria can exploit mechanics to display remarkable plasticity in response to locally changing physical and chemical conditions. Compliant structures play a notable role in their taxis behavior, specifically for navigation inside complex and structured en ...
2019Catchment drainage network scaling laws found experimentally in overland flow morphologies
David Andrew Barry, Andrea Rinaldo, Paolo Perona, Mohsen Cheraghi
The scaling relation between the drainage area and stream length (Hack’s law), along with exceedance probabilities of drainage area, discharge and upstream flow network length are well known for channelized fluvial regions. We report here on a laboratory e ...
2018Parametric study on the influence of jet-like inflows and outflows on fine sediment settling
Anton Schleiss, Pedro Filipe De Almeida Manso, Samuel Luke Vorlet
This paper focuses on the dynamics of fine sediments in reservoirs exposed to hydropower cascade or pumped-storage operations. The aim is at analysing the influence of parameters such as the flow inlet and flow outlet relative position, the jet hydrodynami ...
