Caractérisation et origine des "creuses" : approche sous SIG (exemples en Thiérache)

Abstract : "Creuses" are wooded ravine-like incisions with intermittent flowing that cut the chalky plateaus of the northern Paris Basin. They were formed during periglacial Quaternary periods, as a result of the concentration of the surface runoff leading to torrential flow. Nowadays, these landforms constitute specific environments and reservoirs of biodiversity in a field crops landscape. The determination of the morphometrical parametres and the analysis of the spatial distribution of 98 "creuses", held in a GIS, allow to highlight the respective role of the surface processes and the geological structure in their geometrical features and their localization within the watershed.
