Landslide susceptibility assessment by EPBM (Expert Physically Based Model): strategy of calibration in complex environment

Abstract : Physically based model may be used to assess landslide susceptibility over large areas. However, majority of case studies are applied for complex phenomena for a one event, a little site or over large areas when landslides have simple geometry and environmental conditions are homogeneous. Thus, assessing landslide prone areas for different type of landslides with several geometries and for large areas needs some specific strategies. This work presents an application of a specific procedure based on a physically based model for one complex area with several landslide types. By different steps, it is demonstrated that it is possible to improve susceptibility map and to take into account different slope failure with different depths. This first attempt encourages us to continue on this path in order to improve the existing susceptibility maps in this area.
