Geologia applicata all'ambiente
(objectives)
The objectives of the course are transmission of the basics of applied geology and environmental. The course provides tools and techniques for understanding, analyzing and solving geological problems applied to soil and groundwater protection and management. Geotechnical soil and rock properties, hydrogeological properties, slope dynamics are examined in the geomorphological context of reference for sustainable management and for the prevention of geological and environmental hazards.
Expected learning outcomes
Knowledge and understanding: At the end of the training activity, the student will acquire knowledge on geotechnical soil and rock properties, erosion processes and dynamics of the slopes, groundwater flow. The student will be able to distinguish the most common forms of erosion and landslides, and to analyze slope dynamics. The student will be able to understand the hydrogeological processes by linking them to the geological characteristics.
Applied knowledge and understanding: At the end of the training activity, the student will have to demonstrate that he is able: to interpret the results of a geotechnical characterization of soils and rocks, to read and interpret landslide maps, to analyze hydrogeological data, to calculate flow rate of aquifers.
Making judgments: Through the examples presented during the lessons and exercises, the student will acquire autonomy of judgment based on the acquired knowledge, analyzing different Italian geological, geomorphological and hydrogeological environments.
Communication skills: The student will acquire an appropriate technical language both during the lessons and during the exercises so that they can interact with professionals and experts involved in environmental analysis, management and design. Communication skills will be verified during intermediate tests and/or final examination.
Learning skills: The student must demonstrate his ability to investigate geological, geomorphological and hydrogeological areas which differ from those considered during the course. The student must be able to analyze geotechnical characteristics, slope dynamics and hydrogeological features of an area useful for safeguard and monitoring of the soil and groundwater resources.
