Traffic induced noise analysis for river embankment monitoring

We use traffic induced noise generated by vehicles over a river embankment to retrieve seismic surface wave dispersion curves along the embankment structure. The vehicle transit is tracked in the noise records in space and time and the trace closer to the source at each time interval is used as a virtual source. Interferometry is applied and a dense dataset is obtained and processed to retrieve dispersion curves. The results are compared with active data dispersion curves and show that a small number of vehicle transits allow for the seismic characterization of the embankment and the foundation soil.
