Effects 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 ...
2021Hydrodynamics of mountain-river confluences and its relationship to sediment transport
Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña
Mountain confluences are characterized by narrow and steep tributaries that provide important sediment load to the confluence, whereas themain channel supplies the dominant flow discharge. This results in a marked bed discordance between the tributary and ...
American Geophysical Union2017Numerical simulation of 3D flow in right-angled confluences with bed elevation discordance in both converging channels
The paper studies a combined effect of bed steps (BS) in both converging channels on the 3D flow in a confluence with alpha = 90 degrees. Nine combinations of bed elevation discordance ratio values in the two channels are analysed. It is shown that: 1) a p ...
Elsevier Science Bv2016Hydro-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 ...
2015Hydro-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-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 ...
