The course focus on the theoretical background of geophysical methods applied to civil and environmental engineering, on the application in mining operation, and in study of snow/glacier and permafrost in alpine areas. The course aims to illustrate the data acquisition and interpretation methods of the geophysical parameters.

The course aims to illustrate the data acquisition and interpretation methods of the geophysical parameters.
The student will achieve competences in the context of applications of conventional geophysical surveys to different engineering fields. He/She must demonstrate its ability to plan geophysical surveys in multiple geological and morphological environment, to interpret the results of surveys and to understand the meaning of the geophysical parameters obtained. He/She will also acquire skills in the evaluation of the relationships between geophysical and geotechnical/hydrogeological parameters of soils and rocks. Students will acquire skills on the suitability of geophysical methods to characterise permafrost and glaciers.

The basic knowledges refer to the background in geology, hydrogeology and geophysics with reference to the petrophysical properties of the soils and rocks, the meaning of hydrogeological parameters (density, porosity, content, water permeability), geophysical properties of soils and rocks (electrical resistivity, seismic attributes, electromagnetic parameters) and environmental and geotechnical engineering (mechanical parameters). Basic knowledge on signal acquisition and processing is required. Skills in using computer tools (Matlab/Octave) for geophysical data processing are also required.

Lessons are intended to provide the principles of acquisition, processing and interpretation of geophysical data (about 50 hours). Field tutorials will enable students to learn practical-operational data acquisition methods; the laboratory exercises are aimed at deepening the aspects of data processing and interpretation of geophysical surveys. Laboratory Exercises provide for independent work by the student in the Computer Laboratories at the University.

ModalitÓ di esame: Prova orale obbligatoria;
Exam: Compulsory oral exam;
Gli studenti e le studentesse con disabilitÓ o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'UnitÓ Special Needs, al fine di permettere al/la docente la declinazione pi¨ idonea in riferimento alla specifica tipologia di esame.
Exam: Compulsory oral exam;
The exam consists of an oral test aimed at assessing the theoretical skills and the ability to integrate the results of geophysical surveys into different application contexts. The exam is organized with a question about theoretical aspects and one question about planning and carrying out surveys and interpretation of results. The discussion of the laboratory activities is also part of the exam. The final evaluation is based on the clarity of exposition (5 points), technical skills (5 points), capability to relate the different aspects of the subject (10 points), degree of competence achieved (10 points).
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
