Metodi didattici
The course consists of:
a) 4 cfu (32 hours) of frontal lessons to introduce the topics described in the syllabus;
b) 2 cfu (24 hours) of practical classes, where the students will deepens some of the topics presented during the lessons, by working in small groups on one of the following subjects: i) modeling of the physical processes introduced during the lessons; ii) collect and elaborate geophysical data-sets; iii) design of monitoring networks.
Attendance is strongly recommended.

Modalità di verifica dell’apprendimento e criteri di valutazione
Expected learning outcomes will be verified through the evaluation of two written documents and an oral exam. More in detail:
a) Students will produce a technical report of their activities during the practical classes; the technical report can be presented by a single student or as a group report. Non-attending students are required to perform a modeling/data processing activity previously agreed with the teachers.
b) In addition to the aforementioned technical report, the students will produce a document containing a brief literature review, where one of the topics covered during the lessons will be deepen by reviewing one or more selected scientific papers.
c) During the oral exam, the student will:
i. present the results and the content of the technical report and of the literature review mentioned in the previous points;
ii. be questioned about the topics discussed during the lessons.
The final assessment will be based on the following criteria: ability to present the topics in an appropriate and organic manner, also by using the proper specialist lexicon; strict application of the scientific method; critical reasoning; good command of the topics contained in the presented technical report and literature review.
The final score will be expressed in thirtieth.
