The main objective of this thesis is to produce a methodology spatially characterizing the debris flow susceptibility at a regional scale. The methods used are based on geomatic and statistic fields and aim at integrating the predisposing factors to debris flow activity, especially the morphometry and the potential sediment availability.Robust statistical models allowed to predict the debris flow activity based on the morphometry of the reaches and their catchments in order to discriminate the bedload transport from the debris flow processes.In source areas, the second predisposing factor, i.e. the sediment availability, was first mapped thanks to the analysis of infrared orthophotos (IGN©) and then expertly combined with the morphometric s...
