Transitions of Tonality: A Model-Based Corpus Study
Tonality has been the cornerstone of Western music-theoretical discourse for centuries. This study addresses the subject, using traditional music analysis, data-driven corpus methods, and computational models, concentrating on historical changes of tonalit ...
EPFL2019Hydromorphodynamic 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 ...
Gfg2017Local 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 Sons2016Evaluation des flux de biphényles polychlorés (PCBs) dans les affluents du lac Léman à l’aide de capteurs passifs
The aim of this study is to investigate Lake Geneva’s tributaries using passive samplers in order to establish polychlorinated biphenyl (PCB) fluxes. Silicon rubber sheets are therefore deployed during six weeks at the mouth of eight tributaries and in fou ...
2016Hydro-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 - LCH2015Morphodynamics 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 ...
2015Morphodynamic differences induced by different confluence angles in widen confluences
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso
River widening is commonly used as a solution for the rehabilitation of rivers with the main purposes of allowing the river to adjust to its natural dynamics and to improve riparian and instream habitat for flora and fauna, by increasing the heterogeneity ...
CRC Press/Balkema2014Three dimensional flow field at confluent fixed-bed open channels
Sebastián Guillén Ludeña, António Heleno Cardoso
River confluences are known for their marked 3D patterns and, due to the complexity of local flow features and bed morphology, they require particular consideration. Although there are studies on the flow structure in junctions of two streams, amore detail ...
CRC Press/Balkema2014Herbicides export dynamics of a mid-sized lake tributary: lessons from observations and modelling
Andrea Rinaldo, Enrico Bertuzzo, Bettina Schaefli, Pierre Claude Jean Queloz
We present here a model which couples the hydrologic component and the transport of herbicides within a catchment. The model used takes into account the age structure of the stream water in order to characterize short and long term fluctuations of herbicid ...
2013Hydromorphological implications of local tributary widening for river rehabilitation
Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro, André Roy
The hydromorphological implications of the local widening of a tributary where it enters a confluence were investigated in a laboratory setting that is representative of the 20 major confluences on the channelized Upper Rhone River. Although local tributar ...
