Flood of 23 November 2019 on the French Riviera: a comparison of discharges estimated by image analysis and hydrological modelling
Gauthier Paul Daniel Marie Rousseau, Etienne Robert
The short and heavy rainfall events observed on the French Riviera often lead to flash floods on coastal catchments: during the flood of 2 October 2015, a peak discharge between 185 and 295 m(3)/s was estimated on the Brague at Biot at 8:00 PM, whereas the ...
ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD2022Effects of vegetation at a bar confluence on river hydrodynamics: The case study of the Arno River at Greve junction
River bars often form at river confluences due to variation in flow discharges or in sediment transport capacity; once these bars are grown, they constitute favourable habitats for vegetation development. In this work, we analysed the effect of vegetation ...
2021Hydromorphodynamic effects of the width ratio and local tributary widening on discordant confluences
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso
River training works performed in the last couple of centuries constrained the natural dynamics of channel networks in locations that include the confluences between tributaries and main channels. As a result, the dynamics of these confluences are currentl ...
Gfg2017Hydro-morphodynamics of open-channel confluences with low discharge ratio and dominant tributary sediment supply
River confluences in which the tributary supplies the dominant sediment load, and the flow discharge is abundantly provided by the main river, are typically observed in mountain-river basins. The existent knowledge on the hydrodynamic, morphodynamic and se ...
EPFL2015Morphodynamics in river confluences
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso
Within the fluvial network, confluences are considered particular areas in what concerns ecological connectivity, flood safety and water quality. These characteristics were degraded in many cases, by previous channelization works, which resulted in rivers ...
2015Hydro‐morphodynamic evolution in a 90° movable bed discordant confluence with low discharge ratio
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso
Confluences with low discharge and momentum ratios, where narrow steep tributaries with high sediment load join a wide low-gradient main channel that provides the main discharge, are often observed in high mountain regions such as in the upper- Rhone river ...
Wiley-Blackwell2015Hydro-morphodynamics of open-channel confluences with low discharge ratio and dominant tributary sediment supply
River confluences are not only hot spots of diversity but also main elements for the connectivity in water catchments. In the past century many of the Alpine rivers in Europe as well as their tributaries have been channelized. Especially the confluences ha ...
EPFL - LCH2015Hydro-morphodynamic differences induced by different angles in an experimental discordant confluence
Confluences, within the fluvial network, are considered particular areas with great ecological value, where flow dynamics and bed morphology are complex and highly three-dimensional. Several parameters influence the morphodynamics and hydrodynamics of rive ...
2015Ecomorphodynamic approaches to river anabranching patterns
We investigate the influence of vegetation on river morphological instabilities using an analytical framework. We first discuss the important role of the hydrological (flooding frequency) and biological (vegetation development rate) timescales. As long as ...
Elsevier2015Hydrological Processes in a High Alpine Watershed
Alpine hydrology is particularly challenging due to the complexity of mountainous terrain and the spatial and temporal variability of meteorological parameters such as precipitation, temperature and evaporation. Yet improving our understanding of hydrologi ...
