Abstract
Summary
In this study we investigate the application of seismic interferometry (SI) to seismic reflection data recorded over a landfill. Landfills represent strongly heterogeneous subsurfaces making the seismic reflection imaging challenging. We show that SI improves the imaging of high-density areas, which create scattering events in the recorded data. In addition, we use SI to subsequently predict surface-wave energy and remove it from the original data to improve the imaging of reflectors. The combined interpretation of the conventional reflection seismic data, SI and reflection data with surface waves removed improves the understanding of the landfill body.
