Spatial and temporal variation of landsliding in the Flemish Ardennes, Belgium
10 / 2002 - 10 / 2006
Important questions concerning the landslides in the Flemish Ardennes are: WHERE and WHEN are landslides initiated or reactivated?, WHICH FACTORS are responsible for this initiation or reactivation? And HOW IMPORTANT IS THE DAMAGE caused by landslides? To answer these questions the following objectives are defined: 1. to determine the spatial distribution of the landslides. (by mapping and classifying the landslides in the study area). 2. to determine the factors which cause the initiation or the reactivation of the landslides in the study area. Factors that have to be taken into account are lithology, topography, vegetation, land use, the presence of springs or brooks nearby. 3. to determine the factors which are responsible for the timing of landslide initiation or reactivation on different timescales (short, medium and long term). 4. to create a landslide susceptibility map, which indicates the sites in the study area which are most prone to landsliding in the near future. If possible also a landslide hazard map will be created, as contrasted with a susceptibility map, a hazard map takes into account the element of time. 5. to assess the damage caused by landsliding. This information will be collected from technical services and local people. 6. to formulate recommendations for a sustainable land use.
