Hydromorphodynamic 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 ...
Gfg2017EFFECT OF THE BED LOAD GRADATION ON THE MORPHODYNAMICS OF DISCORDANT CONFLUENCES
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso
Within the fluvial network, river confluences are particular areas characterized by complex hydrodynamic, morphodynamic and sedimentary processes. These processes have been observed to be governed by parameters such as the discharge ratio, the junction ang ...
2017Local tributary widening for river rehabilitation
Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro
The hydro-morpho-sedimentary processes in confluence hydrodynamic zones (CHZ) subject to a local widening of the tributary were investigated in a series of laboratory experiments that were representative of the 20 major confluences of the Upper Rhone River ...
John Wiley and Sons2016Numerical 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 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-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 ...
