At the end of the course students should be able to: - Identify landslide kinematisms and the triggering mechanisms - Select the proper method of slope stability analysis - Select the appropriate shear strength parameters - Evaluate the degree of stability of the slope - Know the main aspects of risk analysis - Select mitigation and stabilization techniques

The student must know the fundamental principles of Physics I; Applied geology; Hydraulics; Geomechanics. In particular the main principles of soil mechanics are considered a compulsory prerequirement and are not explained in class. In the web site of the course recorded lectures on these main principles of soil mechanics will be available.

A. Classification and description of kinematisms and causes of movement I. Natural and Artificial Slopes II. Identification and classification of slope movements III. Description of different kinematisms IV. Landslide triggering mechanisms B. Methods of stability analysis I. Numerical and Analytical methods of slope stability II. The Limit Equilibrium method: the infinite slope and the methods of slices III. Soil slope stability analysis with the Limit Equilibrium method. Drained and Undrained conditions. Shear strength parameters IV. Rock slope stability analysis with the Limit Equilibrium method: Planar failure, Wedge failure, Toppling failure V. Rockfall: factors affecting the process and analysis of motion VI. Risk analysis and Description of some mitigation and stabilization techniques VII. Slope stability in dynamic conditions

The course is organized in theoretical lectures and practical lessons. During the practical lessons the students have to solve exercises by applying the theory explained in lectures. Two practical lessons are devoted to verify the stability of a slope with a software. Each student has to calculate the safety factor of a slope with given paramenters. A global sensitivity analysis, based on the the students' calculations is carried out.

Exam: Compulsory oral exam;

The exam is aimed at evaluating knowledge, competences and skills acquired during the course. The student should be able to carry out stability analyses, to select strength parameters and to evaluate the effect of water pressure in a given case. The exam will be oral through a platform of Politecnico di Torino. A group of 4-5 students will be connected contemporarily according to a calendar that will be published on the course page after the term for exam enrollment. The oral exam comprises 3 main questions. Questions are related to the topics explained in class. Questions consist of discussion of a given topic and/or the solution of a practical exercise. The exam duration is about 2 hours for each group of 4-5 students.
