Landslides
are one of the most significant natural damaging disasters
in hilly environment？[1]. The
locationof our
study area is to the north of Tunisia, home to several manifestations of land
instabilities, we bring to study this area of interest by GIS and geomatic
approach to reduce social economic losses due to landslides.The performance of a
cartographic data base for the landslide study in the Cap-Bon region was
realized through studying geologic 1/50,000 and topographic 1/25,000 maps, aster optic Remote Sensing, land
observation, and climatologic seismic data. These data will be digitalized, georeferenced,
vectorized, spatially analyzed, classified and geotreated in order to produce a
landslides card. The findings have shown that fields with smooth and friable
lithology which are located at rather important seismic zones (more than 4 at
Richter’s scale) have some stability. However, the most endangered zones are in the North-West
around Oued El Kbir and El Ain. Realizing this work helps to determine the most
hazardous zones so that policy makers have an effective field intervention.
