A seismic survey was carried out on a tidal flat in the SW‐Netherlands in order to determine shear‐wave velocities in sediments by means of higher‐mode Rayleigh waves. The dispersion properties of these Rayleigh waves were measured in the 2‐D amplitude spectrum–or f, k ‐spectrum–and resulted in phase velocities for six different modes as a function of frequency (5–30 Hz). These observed phase velocities were inverted for a nine‐layer model for the shear‐wave velocity to a depth of 50 m.
