The aim of the course is to provide geological and geotechnical knowledge for the understanding of the natural phenomena that may affect the development and fruition of cultural heritages, both landscapes and/or architectural heritages. Additionally, the student must acquire appropriate training that allows multidisciplinary relationships with other professionals, which are involved in the protection and management of goods.
Expected learning outcomes
At the end of the course, the student will acquire basic knowledge about the rheology of geological media (soils, rocks and rock masses), of the main geotechnical and geomorphological processes to which they may be subject. The student will therefore be able to formulate reasonable hypotheses on the main issues that may affect the preservation and enjoyment of cultural, landscape and architectural heritage, in relation to their geological and geotechnical context. He will have a geological-technical glossary suitable to understand the content of geological-applicative documents, including thematic maps of susceptibility to instability, hazard and risk.
Lesson period: First semester
(In case of multiple editions, please check the period, as it may vary)
The course covers issues related to the assessment of natural hazards and risks that may compromise or threaten the preservation of cultural heritage, by developing approaches at different scale, from the regional scale to the local site scale. Both scales will include an introductory discussion on the general and theoretical principles related to the subject, with reference to current legislation, the presentation of survey and monitoring tools, analysis methods, and some indications on design and mitigation actions for the preservation of cultural heritage.
