Description :
The applicability of ground-penetrating radar (GPR) for the investigation of loose debris was tested at 2 sites (Viererkar and Zugspitzplatt), in the Northern Alps near the German-Austrian border. The aim of the investigation was to record the base of the debris layer, and thereby acquire an estimation of the backweathering rates of the adjacent rockwalls. The sites are characterized by steep limestone rockwalls and extensive talus accumulations. GPR seems to be a useful tool to evaluate the thickness of slope deposits and may help to separate recent and past debris covers. However, best results are to be expected by using GPR in combination with conventional methods.
