Expected learning outcomes:
Acquire a picture of the professional activity of the geologist in the European and Italian regulatory context, with particular regard to the detection of the elements that contribute to the identification of the geological and environmental hazard for the purposes of risk mitigation. Acquire the theoretical and practical foundations that allow the characterization of the technical properties of geological materials (earths and rocks). Understand the kinematics and dynamics that influence the stability of excavation faces and natural slopes. Learn the minimum concepts and the physical laws that regulate the flow of water in the various types of aquifers, characterizing their hydrogeological properties. Knowing how to plan a survey plan based on the geological-technical or hydrogeological problem to be tackled. To solve simple geological-technical and hydrogeological problems that can influence the stability of the works and of the slopes
• Knowledge and understanding:
Acquire the ability to understand the main geotechnical and geomechanical characteristics that influence the behavior of soils and rock masses in reference to the main civil engineering works. To be able to understand the main geognostic, geotechnical and geomechanical investigations to be applied in relation to the geological context of reference and the type of project work. Understanding the hydrogeological cycle of water and the ways in which it moves underground.
• Ability to apply knowledge and understanding:
The student must be able to determine the main geotechnical and geomechanical characteristics of the different types of terrain and rocks and understand the methodological-operational aspects for the design of an investigation plan. It will have to be able to understand the geological, structural and hydrogeological elements that influence the behavior of soils and rocks.
• Autonomy of judgment:
The student must be able to formulate his own assessment based on the geological-technical and hydrogeological data acquired with a survey plan designed in a manner consistent with the problem under examination.
• Communication skills:
Knowing how to communicate information and solutions to specialists and non-specialists in relation to geological-technical and hydrogeological problems in a clear and concise manner.
It is allowed to take the examination only after having passed the examinations of General and Inorganic Chemistry, Physics and Mathematics and Statistics

In the case of pandemic emergency COVID-19, lectures could be given also via web streaming. For the same reason, indoor and outdoor practicals could be set on online/streaming platforms
Verification of learning
The actual acquisition by students of the expected learning outcomes will take place throughout the duration of the course:
1) During the lectures: students are asked to individually answer questions about the topics covered.
2) During laboratory and campaign activities: students are required to carry out individually and in groups tests for the determination of the properties of soil index, for the determination of the physical-mechanical characteristics of earth and rocks. For each experience carried out in the field and laboratory the written report is mandatary, also for students who were absent or not attending.
3) During the exercises: students individually perform tests (open and multiple answers), elaborate the tests carried out in the laboratory and make exercises on specific topics of the course.
4) During the final written and oral exam: The exam is divided into two parts: during the written exam the student must answer questions on the topics developed during the lectures, in the laboratory and in the field, proposed both in the form of exercises to be carried out as a multiple choice test. The oral test will be based on the discussion of the topics covered during the written test and will be aimed at evaluating the knowledge, skills and competences reached by the student.
The student must demonstrate knowledge of the theoretical basis of the discipline, to know how to design a survey plan, to know how to reason about the geotechnical and geomechanical characteristics of land and rocks on the basis of the geological context of reference.
The score of the exam is assigned by a vote expressed in thirtieths. To pass the exam (vote not less than 18/30) the student, even if not attending, must have delivered all the required reports, demonstrate that he has acquired sufficient knowledge of the geomechanical characteristics of land and rocks, know how to perform a technical and geomechanical geological survey, use a vocabulary appropriate to the discipline, know how to design an investigation plan in simple geological contexts.
To achieve a score of 30/30 cum laude, the student must demonstrate that he has acquired excellent knowledge of all the topics covered during the course and that he has an appropriate and unexceptionable vocabulary, must also have attended at least 90% of the lectures , laboratory and soil.
