« Etude de la suscepliblité liée aux risques géologiques sur le traçon routier cw06 allant d’Ighil Izougaren à Bouandas, wilaya du Sétif. »

Abstract

The issue of natural hazards in general and landslides in particular is a topical issue that marks a memorable action in the world and specifically in Algeria. The CW06 road is exposed each year during the winter period to degradation; which are caused mainly by land movements and particularly of the landslide type and boulder fall. These land movements are triggered either by natural and anthropogenic causes. GIS technologies are the ideal tool for combining the various factors that directly or indirectly affect the stability of slopes. They can be modeled in data and then interpreted in the form of layers of information of causal factors (geological, topographical, hydrological and geotechnical). To produce a map of the sensitivity of the study area. Thematic maps were prepared (density of faults, hypsometric, exposure, precipitation and slope ...) and digital terrain model (DEM) was prepared to examine the conditioning factors of landslides. The analysis of the susceptibility of soils to landslides using GIS is an important step in the protection and prevention of issues against natural hazards. This study showed that the road section studied has recorded areas susceptible to landslides.
