Educational objectives
The course aims to provide students with theoretical and practical knowledge for the understanding of hydrogeological phenomena and related risks.
In detail, students will acquire knowledge on:
- Triggering factors of landslides and slope dynamics;
- Hydrogeological risk assessment;
- Techniques for surveying geo-mechanical parameters of rock masses, useful for their classification and stabilization;
- Monitoring techniques for selecting the most appropriate and reliable alert systems according to the type of phenomenon;
- Management of emergency phases during extreme rainfall events related to the on-going climate of the Mediterranean area.

Main skills:
- Be able to interpret thematic cartography and critically analyze geological and hydro-meteorological data;
- Be able to interact with Local and National Authorities (Civil Protection, Prefecture, etc.), aiming to activate operative protocols during crisis situations induced by hydro-meteorological event;
In order to follow this course with profit, the student must have basic knowledge of applied geology and hydrogeology useful to understand the effect of the human impact, produced by the main engineering works, on environmental systems.
Teaching methods
Teaching consists of classroom lectures and field trips. Some technicians of local government authorities dealing with the hydrogeological risk will be involved by specific seminars.
Following a brief description of teaching methods:
- Classroom lectures: the topics are presented to students who are stimulated and involved during the lessons with questions and opinions on the issues discussed, also through the illustration of selected case studies.
- Field trip: students are involved in some field and lab experiences concerning the hydrogeological instability and monitoring.
Other information
The attendance of teaching activities is optional but strongly advised. Students have to be equipped with their own scientific calculator and drawing kit.
Learning verification modality
The exam consists of a multiple choice test questions aiming to ascertain the knowledge, skills, and abilities of the student in communicating and solving the problems related to the hydrogeological risk. The questions concern the different topics discussed during the course, taking into account both theoretical and practical aspects.

Information for students with disabilities are available at http://www.unipg.it/disabilita-e-dsa
