Characterisation of a Meander Structure using MASW and Direct Push-techniques

The use and combination of geophysical methods for the geomorphological characterization of subsurface features is becoming increasingly important. In order to delineate a filled in abandoned meander in the North of Saxony, Germany a MASW survey was conducted. A combination of different offsets provides reasonable results for delineating fluvial-geomorphological features of both, shallow and deep parts of the resulting pseudo-2D S-Wave velocity sections. Furthermore a shot-geometrical dependency for surface wave seismic can be inferred. The MASW data were compared and discussed with Direct Push invasive measurements, i.e. cone penetration testing (CPT) and soil core sampling.
