Obiettivi Formativi
By the end of the course, the student must be able to:
- recognize type and occurrence of natural and man-made slope movements
- assess/evaluate the key geotechnical parameters that govern slope stability
- use methods for slope stability assessment, modelling of slope movement and back-analysis of failed slopes
- judge capabilities and limitations of slope stability analysis software
- decide the fundamental steps for landslide investigations and select remedial measures
- use the appropriate terminology of the discipline
- apply knowledge to practical problems.

Two intermediate tests, project (including technical report and discussion) and oral (optional if the average of the votes is greater than 18) are needed to verify if the student is able:
- to recognize type and occurrence of natural and man-made slope movements
- to assess / Evaluate the key geotechnical parameters that govern slope stability
- to use methods for slope stability assessment, modelling of slope movement and back-analysis of failed slopes
- to judge capabilities and limitations of slope stability analysis software
- to decide the fundamental steps for landslide investigations and select remedial measures
- use the appropriate terminology of the discipline
- apply knowledge to practical problems.
Intermediate tests can be replaced by oral discussion.
