Job description

The topic ‘3D seismic imaging of the near surface’ has a wide range of applications. These include geotechnical, geophysical, archaeological, infrastructural/NDT (non-destructive testing), and safety and security related applications. Specific applications also contribute to the energy transition. For instance, the determination of mechanical properties of the shallow subsurface for the purpose of wind turbine foundation design, or the imaging/monitoring of the near surface for CO2 sequestration activities. The scale, and hence the frequencies involved, vary considerably among the listed applications. Notwithstanding, they are all based on the same (wave) physics.

Extracting information about the near surface can be achieved using surface waves. The current way of extracting information from surface waves is usually based on retrieving information from their dispersion curves via a 1D tomographic inversion per record. By combining these 1D profiles, a 3D image is subsequently obtained. The (lateral) resolution of these images, however, is far from optimal.

Project goals

  • To make an inventory of the various near-surface imaging applications and methods, and connect with groups within TU Delft that deal with these. Creating the circumstances for optimum cross-fertilization between these groups/application areas.
  • To develop a method for improving the (lateral) resolution of 3D (x,y,z) near-surface images in terms of shear-wave velocity, and possibly density. In addition, detection, localization and classification of subsurface anomalies (scattering objects, voids) is part of the goals.
  • To demonstrate the improvement for a number of different application areas (e.g., geotechnical and NDT) using both synthetic and real data.

The PhD project is financed by the Delphi Consortium. For more information, please click here.
