Les fleuves sont considérés comme des voies de transfert importantes où les macrodéchets plastiques seraient linéairement et continuellement transférés vers l'océan. Récemment, certaines études démontrent pourtant que les macrodéchets peuvent s'accumuler dans les systèmes fluviaux durant des années, voire plusieurs décennies. Tout l'enjeu est de sa...
In the field of hydrology, the Geomorphological Instantaneous Unit Hydrograph (GIUH) is central to describing a watershed response. The application of GIUH is extended to individual hydrological events by accounting for the influence of rainfall spatial distribution. A method is proposed herein to identify the Geomorphological Instantaneous Unit Hy...
The effects of spatial variability of rainfall, geomorphology, and climatology of precipitation and temperature on the hydrologic response remain poorly understood. This study characterizes the catchment response in terms of a variable called flashiness, that describes the severity of the flood response as the rate of rise of the unit discharge. It...
The present work is based on The RYSCMED project supported by PHC-UTIQUE 2016-2018 (16G 1005 –34854QC). The RYSCMED is an interdisciplinary project which gathers different disciplines (e.g. sedimentology, hydrology, geochemistry, ecology, paleontology, biochemistry, archeology) to quantify the sediment flow of the land-sea. This research aims at id...

Unlike alpine-like high mountain ranges, medium-high mountain ranges are generally not considered to be avalanche-prone areas. However, when terrain and climate characteristics are favourable, significant avalanche activity can affect these environments, playing a major role in landscape structuring. Specifically, avalanche-forest interactions leav...
On forested paths, dendrogeomorphology has been demonstrated to represent a powerful tool to reconstruct past activity of avalanches, an indispensable step in avalanche hazard assessment. Several quantitative and qualitative approaches have been shown to yield reasonable event chronologies but the question of the completeness of tree-ring records r...
À l'heure de la GEMAPI (Gestion des milieux aquatiques et protection contre les inondations) les praticiens ont besoin, lors de l'étude de nouveaux aménagements de cours d'eau, d'outils pour évaluer le volet GEMA qui soient complémentaires aux analyses coûts-bénéfices et multicritères (ACB et AMC) développées pour évaluer le volet PI. L'état géomor...
