Mouvements de masse et dynamique d’un géosystème alpestre : étude dendrogéomorphologique de deux sites de la vallée de Boulc (Diois, France)

Abstract: Résumé Les mouvements de versant constituent un risque naturel majeur dans les Alpes du sud où la nature du terrain et le climat sont particulièrement favorables à leur développement. Ils représentent également une source importante de sédiments pour les cours d'eau. L'objectif de cet article est de dater, au moyen de l'analyse dendrochronologique, les mouvements ayant affecté deux versants instables d'un même bassin hydrologique. Les réponses de 41 pins sylvestres ( Pinus sylvestris … Show more

“…The earliest dendrogeomorphic studies of landslides date back to Alestalo (1971), and the method has been used ever since extensively in the United States (e.g., Reeder, 1979;Hupp, 1983;Osterkamp et al, 1986;Williams et al, 1992;Carrara and O'Neill, 2003), in Canada (Butler, 1979), but also in Quebec (Bégin and Filion, 1988). In Europe, tree rings have been used to reconstruct the frequency and landslides reactivation in the French (Braam et al, 1987;Astrade et al, 1998) and Italian Alps (Fantucci and McCord, 1995;Fantucci and SorrisoValvo, 1999;Santilli and Pelfini, 2002;Stefanini, 2004), in the Spanish Pyrenees (Corominas and Moya, 1999), and in the Flemish Ardennes (Belgium; Van Den Eeckhaut et al, 2009). …”

“…The first dendrogeomorphic study of a landslide body dates back to Alestalo (1971), and similar field and laboratory approaches have been used ever since in North America (Shroder, 1978;Butler, 1979b;Reeder, 1979;Hupp, 1983;Jensen, 1983;Osterkamp et al, 1986;Bégin and Filion, 1988;Williams et al, 1992;Carrara and O'Neill, 2003). In Europe, dendrogeomorphic tools were introduced much later to assess the frequency and reactivation of landslides in the French Alps (Braam et al, 1987;Astrade et al, 1998;Lopez Saez et al, 2012a,b), the Italian Apennines (Fantucci and McCord, 1995;Fantucci and Sorriso-Valvo, 1999;Stefanini, 2004), the Spanish Pyrenees (Corominas and Moya, 1999), or the Ardennes (Belgium; Van Den Eeckhaut et al, 2009). Table 3 provides an overview of past studies.…”

“…In the Diois mountains (Drôme), the Bonneval-en-Diois debris flow (Figure 8) was studied in 1990(Descroix, 1994. This debris flow and the Boulc landslide, very close to Bonneval (10 km downstream), were the subjects of a historical synthesis and a risk analysis (Leone, 1996) and of a recent study based on dendrochronology and geomorphological datings (Astrade et al, 1998). These methods led the authors to give precise dating for the last 50 years.…”
