Élaboration d'une typologie des formes de vallées. Application au bassin de la Maine (plateaux du Nord-Ouest de la France)

Abstract: International audienceValleys are rarely studied as specific relief elements. We propose a typology based on morphological data processing from a digital elevation model (DEM). Valleys were extracted from the hydrographic network and STRAHLER stream ordering, as well as a width strip, which varied depending on the ordering. Elevation data were processed using the "Topographic Position Index" (TPI). Changes in the slope at the bottom and on the sides of the valley as well as the width of the valley floor were t… Show more

“…Taxonomy methods are welcome wherever problems of classification arise—be it in the biological sciences: phylogenetics, evolutionary biology, or in the human and social sciences: stemmatology, linguistics, psychology, economy, geography, and sociology (among others: Barbrook, Blake and Robinson 1998; Reinert 1987; Rexová, Bastin and Frynta 2006; Van Meter et al 1987; Baldwin et al 2012; Alhaskeer et al 2014; Van Meter 1999). Leaving aside the differences, all scholars build trees based on the similarities and differences between the taxa under study.…”

“…Further research results from various areas proved, however, that these muds were deposited throughout the late glacial and Holocene, although at a different rate (Kalicki, 2006). Many authors, however, still closely associate the appearance and sedimentation of these muds with an anthropogenic factor (e.g., Klimek, 1988Klimek, , 2003Lipps, 1988;Hiller et al, 1991;Pastre et al, 1991;Litt, 1992;Brown, Keough, 1992a, 1992bAlexandrowicz, 1996), which undoubtedly had a strong influence from the Middle Ages (e.g., Schirmer, 1995;Klimek, 1996;Houben, 2003) and initiated such deposition in small mountain catchments in the last few centuries (e.g., Hong, 1995;Mäckel and Zollinger, 1995;Klimek et al, 2003;Kukulak, 2004).…”
