Continuous monitoring of morphological changes from sediment augmentation by field measurements and flume experiments
Giovanni De Cesare, Christian Mörtl
In this study, we present results from continuous field monitoring and a flume ex-periment of a sediment augmentation measure in a residual flow reach of the Swiss midlands. A straight morphological channel with fixed bed material was constructed to repres ...
2023Influence of channel geomorphic units on bedload transport and river morphology during low‐magnitude bed‐forming floods coupled with sediment augmentation
Giovanni De Cesare, Severin Stähly, Christian Mörtl, Robin Schroff
In this study, we map different types of channel geomorphic units in a sediment-starved, residual-flow reach before and after an artificial flood. Bedload particles of a previous sediment augmentation measure are tracked with passive integrated transponder ...
2023Simulation 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 ...
2023Impact of substrate clogging on vertical connectivity
Giovanni De Cesare, Romain Maxime Dubuis, Robin Schroff
Connectivity between the hyporheic zone and the flow is essential for the development of benthos and the reproductive success of spawning fish. The infiltration of fine sediment leads to clogging of the riverbed, reducing porosity and vertical water exchan ...
2023Sediment continuity and augmentation measures
Giovanni De Cesare, Robin Schroff
Impaired sediment transport can have numerous adverse impacts on the eco-morphodynamics of the riverscape. If well designed, sediment augmentation measures present a promising mitigation approach at different scales. This chapter focuses on flume experim ...
2023Étude du ruissellement de surface sur le territoire jurassien - Analyse hydrologique et évaluation du risque
Le ruissellement de surface occupe une place importante dans la problématique d'inondation. Cette étude a cherché à caractériser les paramètres à ajuster pour une modélisation hydrologique visant à évaluer ce danger. Par l'étude d'un secteur pilote d'envir ...
2023Un outil pour évaluer l’adaptation des villes au changement climatique: la Matrice Bleue-Verte
Giovanni De Cesare, Sabine Chamoun, Loé Maire
La majorité des zones urbaines à travers le monde sont fréquemment touchées par le changement climatique, notamment à travers les effets d'îlots de chaleur ou l'augmentation de la fréquence des inondations. Les villes éponges, concept développé en Chine en ...
2023Contribution of the Hydraulic Laboratories of the Swiss Federal Institutes of Technology to Dam Safety
Giovanni De Cesare, Azin Amini, Samuel Luke Vorlet
Bien que la construction de barrages en général et l’hydraulique des barrages en particulier soient des domaines techniques très développés, le potentiel de risque associé aux barrages justifie dans la plupart des cas la vérification et l’optimisation de l ...
2023Effects of water releases and sediment supply on a residual flow reach
Giovanni De Cesare, Robin Schroff, Camille Blanck
An artificial floods program has been implemented on the Sarine residual flow reach, downstream of the Rossens dam. Two artificial floods were released in 2016 (coupled with sediment augmentation) and in 2020. A natural flood occurred in 2021. The indicato ...
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 ...
