L’utilisation d’un modèle géospatial pour l’évaluation de l’influence des changements climatiques sur les mouvements de terrain dans la wilaya de béjaia (côté Est)

Abstract

The objective of this work is to contribute to the study of natural hazards (landslides) in the eastern part of the Wilaya of Bejaia. The essential first step in natural hazard studies is a historical research of past events. Using the visually-interpretation of satellite Ortho Photo, we detected and synthesized 636 historical shifts that have affected our study area. We have largely operated geographic information systems (GIS) for mapping the causative factors landslides inventoried this approach allows to study the distribution of the phenomenon its activity, and its links with certain geological setting, geomorphologic and climatic conditions. The results indicate that the eastern part of the province is affected, with a significant concentration of landslide
