High resolution hybrid seismic investigation for mapping the weathering layer thickness and for estimating the bedrock quality near a nuclear power station; 2 hybrid seismic profiles totalling 400 m, depth of investigation: 50 m. Down-hole measurements in 8 borholes down to 50 m to determine p- and s-wave-velocity to derive the poisson’s ratio. Multichannel analysis of surface waves (MASW) to determine the shear-wave velocity field; 2 profiles of 200 m length each. Crosshole test and crosshole tomography over three boreholes.
