Obiettivi dell'insegnamento

Geophysical sounding is used for the remote detection and characterization of a target in the subsurface, producing images of its relevant properties for engineering, environmental, geological applications.

The course presents the seismic, electrical and electromagnetic investigation methods, from the fundamental theory up to the data collection and processing, with field lessons, computer lab sessions and presentation of case histories.

Course objective is to give the students competences and skills in the field of geophysical imaging.

Dublin Descriptors

Expected learning outcomes

1 - Knowledge and understanding

Students will gain clear understanding about:

  • the physics behind each geophysical method (seismic, electrical and EM)
  • the integration of surface and subsurface remote sensing technologies
  • signal processing methods for the treatment of seismic, electrical and EM geophysical data

2 - Applying knowledge and understanding

Students will be able to:

  • design a seismic, electrical or EM survey
  • define a seismic, electrical or EM data processing flow chart.
  • use and modify specialized SW to simulate a geophysical “scenario” (e.g. the elastic wave propagation in a layered medium) and to understand “experimentally” the theoretical principles.

3 - Making judgements

Students will be able to:

  • define the application fields and limits of seismic, electrical and EM geophysical method
  • analyze a geophysical image
  • read and understand a standard case history report 

4 - Communication

Students will learn to:

  • write a technical document on a specific case study (e.g.: design and implementation of a remote sensing survey, algorithm development, system analysis, etc.)
  • explain the physical principles and the way of operation of seismic, electrical and EM geophysical methods
  • design prototypal demonstrations by modifying/tuning specialized SW deveoloped/provided during the course
