Abstract : This article examines the potential sensitivity of the soil to water erosion in the West Bekaa from a qualitative approach. Using a GIS, it allows to cross data such as: the erodibility and crusting of the soil, slope gradient and soil coverg influence on erosion. The result of the mapping allows to identify areas threatened by erosion in order to protect them. Threequarters of the study area have a high or very high sensitivity. For us, it is to present a method that can be applied to other fields.
