Learning objectives

Knowledge and ability to understand: learn the basics of the equations describing the flow of fluids (in particular in porous media) and of the advective transport of contaminants.
Knowledge and understanding skills applied: ability to read and understand how to apply the theoretical knowledge acquired to examples of the modeled case studies.
Making judgments: knowing how to evaluate the content of innovation present in the examples of case studies based on the acquired theoretical knowledge.
Communication skills: knowing how to present and organize the exposition of a specialized subject based on the developed topics.
Ability to learn: to learn more about a topic starting from previous knowledge applied to similar examples and applications of modeling a fluids flow problem.

Course unit content

The course intends to provide on one side, an overview of mathematical models describing the flow of fluids (especially in porous media) and the advective transport and to the governing equations that describe these phenomena.
On the other hand, it intends to provide numerical calculation tools for modeling and forecasting in time and space using examples of real case studies.

Teaching methods

Lectures and activities in the laboratory of modeling and simulations of case studies and real cases.

Assessment methods and criteria

The ability to autonomously use, integrate and communicate the student's knowledge is verified in different phases of the course, through problems assigned and solved by the students.
The acquisition of knowledge is verified through an oral exam, in the course of which theoretical knowledge is applied to real case studies. 'Lode' is given in cases in which an extraordinary ability to face and solve the problems posed is demonstrated. For foreign students English is used.
