Description :
Three geophysical methods, ground penetrating radar, 2D-resistivity and seismic refraction were applied to two landform complexes in a high-alpine valley of the Valais to investigate their internal structure. Results of the different methods were analysed separately, before conclusions about sediment thickness and geomorphologic implications were drawn. The combined geophysical investigation produced a detailed image of the subsurface composition of the 2 landform complexes that enhance the understanding of the paraglacial landform evolution in this hanging valley.
