Suitable for English-speaking students

Objectives

To provide students with an integrated view of different  geophysical methods within their geological context, namely: the physical principles they are based on, the most commonly used interpretation techniques, the related equipments and application domains, in particular mining, geotechnical, geo-environmental, archaeological and civil/structures.

Learning outcomes and competences

Ability to select adequate methods and to conduct field work, including acquisition, data analysis and basic interpretation.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Mathematical Analysis I and II; Physics

Program

Presentation. Course overview;
Summary of the different methods to be developed.

Geophysical Exploration
- seismic methods including refraction, reflection, down-hole, up-hole, cross-hole, tomography;
- geo-electrical methods including resistivity, spontaneous and induced polarization, electrical profiles, vertical electrical sounding (VES);
- electromagnetic radiation and induction methods in particular VLF and ground penetrating radar (GPR);
- gravimetric method;
- magnetic method.

For each method: - its geological context; - description of physical principles, field survey techniques and related equipment and interpretation techniques; in some cases such as in gravimetric, seismic and resistivity, the direct and inverse problems will be considered; - discussion about the application domains. Theoretical-practical complements of the considered subjects, namely related to the direct problem. Presentation of geophysical equipment, namely for resistivity, GPR and seismic, and their use during field classes, in short site investigation surveys. Interpretations examples with field data: Field lessons are planned in which some equipment will be used, namely for seismic methods, electrical resistivity, GPR and VLF. Examples of signal handling using the Excel spreadsheet, MatLab and ReflexW software. Presentation of public domain software for solving the direct problem in the resistivity method.

Eligibility for exams

Attendance according to the FEUP General Evaluation Rules. Must have  at leat 6.5 in the global distributed evaluation, "Avaliação Distribuída", which weighted average includes: two mid-term tests, 60%; assignments and performance, 40%. 

Calculation formula of final grade

The final mark will be the mark of the distributed evaluation/“Avaliação Distribuída”.

Non-approved students having obtained frequency/ “Obtenção de frequência”, may access a written resit exam. Final classification weighted average: 70% for resit exam plus 30% for assignments and performance components of “Avaliação Distribuída”.

Accreditation of marks exceeding 18 points shall be validated through an oral exam.

Examinations or Special Assignments

Not foreseen.

Special assessment (TE, DA, ...)

According to the general evaluation rules.

Classification improvement

Written and/or oral exam, possibly coincident with the resit/appeal exam.
