The Role of Paraglacial and Periglacial Processes in Shaping Glacial Valleys
Are U-shaped valleys, long regarded as the exclusive result of glacial erosion, significantly shaped by processes occurring during interglacial periods? This study challenges conventional glacial geomorphology by quantifying the sedimentary contributions of interglacial sequences.Focusing on the Nesdalur valley in Iceland's Westfjords—a U-shaped valley sculpted by repeated glaciation-deglaciation cycles and marked by its Tertiary basalt structure…
Hybridizing Geographically Weighted Regression and Multilevel Models
Multilevel models are one of the main statistical methods used in modeling contextual effects in social sciences. A common limitation of these methods is the use pre‐set boundaries—usually administrative units—to define contexts, when these boundaries do not always match up with the “true” causally relevant contexts that may affect the outcomes of interest. In this study applied to the obesity geography in the Paris area (France), we propose a ne…
Spatial patterns of vineyard landscape evolution and their impacts on erosion susceptibility
Erosion susceptibility in vineyards is approximately one order of magnitude above the reference level calculated for all agricultural activities, and preventing soil erosion is thus one of the most important environmental issues in vineyards. Spatially explicit models are necessary to address the coevolution of erosion susceptibility and anthropogenic practices because of the heterogeneous spatial patterns of erosion within vineyards. In this pap…
An early Holocene age for the Vatn landslide (Skagafjörður, central northern Iceland)
Recent research in northern Iceland has highlighted a significant period of rock slope instability during the early Holocene due to the combined effects of postglacial rebound, relative sea-level fall, and glacially oversteepened mountain slopes. Using the Vatn landslide (Skagafjörður, central northern Iceland) as an example, this paper focuses on this period and describes the sequence of events that led to landsliding. Geomorphic mapping, strati…
The Höfðahólar rock avalanche (sturzström)
The Höfðahólar rock avalanche, in the Skagafjörður area of northern Iceland, was investigated on the basis of a geomorphological analysis of its landforms and close surrounding environment. Thanks to sound chronological constraints ( 14 C dating from birch remnants in peat areas that developed within depressions over the chaotic rock-avalanche deposit, tephrochronological sequences resulting from subsequent ash fallouts over the deposit, calibrat…
Entretien avec Yvette Dewolf

Les variations récentes (1975-2000) de l’englacement dans le Massif de l’Aconcagua (Mendoza, Argentine)
La région de Mendoza est particulièrement vulnérable au réchauffement climatique. Les glaciers du massif de l’Aconcagua ont amorcé un important retrait depuis la fin du Petit Âge de Glace. Or la disparition de ces glaciers risque d’entraîner une modification des régimes hydrologiques qui, jusqu’à présent, se caractérisaient par de hautes eaux estivales. Ce pic estival pourrait à l’avenir être atténué et remettre en cause les stratégies de gestion…
