An approach towards deterministic landslide hazard analysis in GIS. A case study from Manizales (Colombia)

Auteur(s) et Affiliation(s)



Description :
A one-dimensional deterministic slope stability model (infinite slope model) was used to calculate average safety factors and failure probabilities for the city of Manizales, in central Colombia. An engineering geological data base has been created on the basis of a series of parameter maps (geology, geomorphology, Digital terrain models and slope classes), using logic reasoning in Geographic Information Systems (GIS). The results presented are a first approach towards a deterministic landslide hazard analyysis using GIS.
