TRANSPORT AND DIFFUSION IN THE OCEAN AND IN THE ATMOSPHERE
Lectures are in Italian. The professor is available to interact in English in class and during exams
The course aims to provide students with the basic, theoretical and applied knowledge, of the so-called Environmental Fluid Dynamics.
- Knowledge and understanding: The student must demonstrate the knowledge of the course contents and the best practices to tackle phenomena inducing chenges in the concentration of substances within a fluid environment.
- Ability to apply knowledge and understanding: The student must demonstrate the ability to apply the correct approach to situations of input of substances into a fluid environment, on the basis of the available data and of the requested output.
- Autonomy of judgment: Students must be able to independently evaluate different situations wrt the standard ones presented by the teacher during the course, and to adopt the best resolution methods.
- Communicative Skills: The student must have the ability to present the course material within an oral examination using the correct scientific language.
- Learning Skills: Students must be able to continue their education in the future through the consultation of texts and publications (mainly in English) in order to acquire the ability to deepen the understanding of transport and transformation processes in a fluid environment.
