The course aims at providing students with fundamental and practical knowledge of nondestructive testing methodologies for subsoil and (recent and historical) manufacts characterizations.
Basics of mechanics, electromagnetism, and applied geology will be taught. Moreover, within the course framework, for each methodology, after the introduction of the physical principles, observation techniques, and data processing and interpretation strategies, also practical laboratory and fieldwork activities will be performed with the active involvement of the students.
None, except for preparatory courses as indicated in the general degree plan.
Clearly, some prior knowledge of the main geophysical methodologies might be helpful
Introduction to the geophysical methods (0.5 hour)
Gravimetry: Earth gravitational field and its anomalies; data acquisition strategies for absolute and relative measurements; gravimetric surveys; processing and corrections of the observations; anomalies and filtering; qualitative and quantitative interpretation of the data (7 hours).
Seismics: elastic waves; Huygens' principle, wave fronts and seismic rays; Snell's law; Fermat's principle; attenuation; seismic refraction: data collection, processing and interpretation; down-hole, up-hole, cross-hole; seismic tomography; surface wave methods; acquisition devices; applications (7 hours).
Electrical methods: electrical properties of materials: resistivity, permittivity, chargeability; acquisition devices; self-potentials; induced-polarization; electrical resistivity tomography (7 hours).
Georadar: physical principles: propagation, attenuation and reflection of electromagnetic waves. Penetration and resolution; data processing, visualization and interpretation (6 hours).
Remote sensing: thermography and multispectral images (2.5 hours).
Lab and field activities (10 hours).
The course includes:
1) lectures and exercises with use of instruments (30 hours);
2) fieldwork and practical activities, and, possibly, data processing at the computational lab (10 hours)
Verification of learning
The exam consists of a written test with eight questions/exercises; for each question, the student gets a grade from 0 to 4. The final grade is simply the sum of the individual grades. In special cases, upon the student's request, the examination can be oral.
