Journal ArticleDOI
Concepts of hydrological connectivity: Research approaches, pathways and future agendas
Louise J. Bracken,John Wainwright,Genevieve Ali,Doerthe Tetzlaff,Mark W. Smith,Sim Reaney,André G. Roy +6 more
TL;DR: The extent to which different concepts of hydrological connectivity have emerged from different approaches to measure and predict flow in different environments is evaluated and the extent towhich these different concepts are mutually compatible is discussed.
Journal ArticleDOI
Flow and sediment dynamics in channel confluences
M. Leite Ribeiro,Koen Jacques Ferdinand Blanckaert,Koen Jacques Ferdinand Blanckaert,André G. Roy,Anton Schleiss +4 more
TL;DR: In this paper, a conceptual model is proposed for the hydromorpho-sedimentary processes in the Upper Rhone River, and compared to existing conceptual models for confluences with different characteristics, which is characterized by maximum velocities occurring near the bed, and a considerable increase in turbulent kinetic energy generated in the shear layer at the interface of the flows originating from the main channel and the tributary.
Journal ArticleDOI
Hydromorphological implications of local tributary widening for river rehabilitation
M. Leite Ribeiro,Koen Jacques Ferdinand Blanckaert,Koen Jacques Ferdinand Blanckaert,André G. Roy,Anton Schleiss +4 more
TL;DR: The hydromorphological implications of 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.
Journal ArticleDOI
Linking spatial patterns of perched groundwater storage and stormflow generation processes in a headwater forested catchment.
Genevieve Ali,Caroline L'Heureux,André G. Roy,André G. Roy,Marie-Claude Turmel,François Courchesne +5 more
TL;DR: In this paper, the authors examined hydropedological patterns and storage-discharge relationships towards catchment process understanding at a small forested site, the Hermine (Laurentians, Quebec, Canada).
Journal ArticleDOI
