Objectives

The course aims at providing students with fundamental and practical knowledge of nondestructive testing methodologies for subsoil and (recent and historical) manufactures characterization.
Basics of mechanics, electromagnetism, and applied geology will be discussed. In addition, within the course framework, for each methodology, after the introduction of the physical principles, measurement techniques, and data processing and interpretation strategies, also practical laboratory and fieldwork activities will be performed with the active involvement of the students.

Prerequisites

None, except for preparatory courses as indicated in the general degree plan.
Clearly, some prior knowledge of the main geophysical methodologies might be helpful

Contents

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).

Teaching Methods

The course includes:
1) lectures and exercises with the use of instruments (30 hours);
2) fieldwork and practical activities, and, possibly, data processing at the computational lab (10 hours).

To face the potential problems connected with the pandemic outbreak, the lectures will be held also on-line. Copies of the recorded lectures will be made available upon request. In addition, the more practical parts will be, in case, offered by means of the ICT tools available.

Verification of learning

The assessment of the acquired competencies consists of the submission and discussion of a research product by the student.

Due to the pandemic situation, the discussion might be held via the alternative ICT tools available.

The student is supposed to demonstrate a good understanding of the principles of the non-destructive methodologies for the characterizations of the manufactures and subsoil, and of the rationale and frameworks to apply them effectively.

The exam grade is in thirties.
In the exam evaluation, the exam grade is based on the following criteria:
1. level of understanding of the principles of the methodologies used in the student’s research product
2. level of critical thinking concerning the effectiveness and appropriateness of the solutions adopted in the student’s project
3. ability to extend the studied methodologies to different problems/contexts
4. exposition clarity
5. logic coherency in the presentation of the project

Meeting requirement no.1 is necessary to get a grade greater than 20/30. A grade greater than 27/30 can be obtained by the student who meets all four criteria.
