How to link statistical and deterministic models for assessing landslide hazard?

Résumé

Landslide hazard assessment at coarse scales (1:50,000 to 1:10,000) is often restricted to the analyses of landslide susceptibility by direct or indirect approaches, i.e. the spatial and static component of the hazard which is considered as a ‘relative hazard assessment', while the analyses of the probability of landslide occurrence, i.e. the temporal and dynamic component of the hazard, is restricted to detailed scale (1:10,000 to 1:2,000). Because the scales of work are different for both approaches, the thematic data are dissimilar especially in terms of nomenclature and investigation scale. Therefore, linking both methods to obtain realistic landslide hazard maps needs specific strategies. The objective of this study is the application of a statistical and a deterministic dynamic model on the same dataset of environmental factors to produce hazard maps at 1:10,000 scale.
