Advanced Numerical Methods for Environmental Modeling

Lecturers: Ilya Peshkov (UNITN/DICAM), Annunziato Siviglia (UNITN/DICAM)

Timetable: 2.5 weeks intensive course May 15 – 31, 2023

For convenience of the non-local participants, the course will be giving in a mixed online-on-site format. The online lectures will be available via ZOOM software.

Summary

The course on advanced numerical methods for modeling of environmental processes consists of a structured intensive 2.5 week program of 80 hours of theoretical lectures and computer laboratory exercises on advanced numerical methods for hyperbolic and nonlinear parabolic partial differential equations with applications in environmental engineering and science. The course covers standard explicit and flux-splitting finite volume methods for hyperbolic equations, semi-implicit finite volume methods for hyperbolic and nonlinear parabolic equations, e.g. shallow water equations, sediment transport (Exner equation), solidification (icing, Stefan model), ecomorphodynamic (vegetation growth, death and mutual interaction with sediments). Special emphasis is put on practical implementation of the discussed numerical methods. The lectures on the theory will be supplemented with laboratory-based computer exercises to provide hands-on experience to all participants on the practical aspects of numerical methods for hyperbolic and parabolic problems and applications using MATLAB software. The course is primarily designed for Master and Ph.D. students in applied mathematics, engineering, physics, computer science and other scientific disciplines.
