This paper presents the first results of a study which aims at devising a hydro- geomorphic river typology of the Alsatian watershed of the Rhine rift valley. A Multiple correspondance analysis and a specific stream power map of 187 sites allow an initial morpho- dynamic régionalisation of the rivers under consideration. Use of a Hierarchical ascendant classification for the sites of the III and Rhine rivers and the division of the Eberbach river into different sections based on the longitudinal evolution of the unit stream power (an adaption of the method of Bernot et ai, 1996) shows how this initial régionalisation can be refined to produce a detailed typology. Finally, the muttivariate analyses allow a hierarchy to be established of different variables, which could be used in other geographical contexts. Source : Éditeur (via Persée) |
