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 equations describing 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.
