This summer school is aimed at Ph.D. students, postdocs and engineers with a background in mathematics, fluid mechanics or environmental science, who wish to learn more about environmental fluid dynamics. The school includes four « core » courses on : fundamentals of fluid dynamics, flow instabilities, environmental fluid dynamics & cryosphere, and atmosphere & ocean. In addition to those core lectures given each year, applied lectures on more specific topics will also be offered with topics chosen every year according to the invited lecturers. Possible topics include: renewable energies, bioconvection, physical oceanography, geological flows, climate change. The originality of this school, compared to other similar events, is that the lectures are accompanied by numerous numerical and experimental afternoon sessions, where students have the opportunity to get hands-on experience in the physical processes studied in the lectures.
