Learning Objectives
The course aims to provide students with information on the following topics:
Acquired kwnoledge:
- applicability of monitoring instruments in different geological and geomorphological contexts
- analysis and interpretation of data collected by a monitoring system
Technical skills
- design and implementation of a monitoring system
- critical analysis, assessment and synthesis of data collected
Coomunication skills:
- dissemination of data collected by a monitoring system
Prerequisites
Knowledge of geology, geomorphology and applied geology.
Basic knowledge of remote sensing and GIS applications/techniques
Teaching Methods
- Frontal lessons with with the use of a video projector;
- Practical exercise;
- Seminars of expert scholars on particular topics
Further information
Highly-recommended attendance to the lessons for the interdisciplinary nature of the topics
Type of Assessment
Final oral exam to determine the level of the student knowledge and link capability in between the different subject of the course. Each student will have to answer some questions related to the main topics discussed during the course. Written tests or intermediate checks are not foreseen. Written (practical) exercises are possible in the classroom, but they do not contribute to the final evaluation.
The exam topics are only those covered during the course and contained in the distributed teaching material.
Exam dates are defined by the official calendar.
