Learning Objectives

The student will learn about the fundamentals of linear wave theory, wave propagation, sea waves, wave hindcasting methods, wave climate analysis, coastal morphodynamics, harbour and coastal structures. At the end of the course, also thanks to the complementary practical exercises, the student will be able to carry out a full study of the wave climate, which is needed for design of coastal and maritime works.

Course Structure

The course is organized as follows:

-traditional lectures, carried out using a participative approach in order to obatin the maximum involvement of the students;

- practical exercises, carried out in informatic classrooms. Such excercis are supervised in order to be sure that all the students will learn during the classtime how to apply the most important concepts and methods to be used in the field of maritime hydraulics, coastal and port engineering;

-guided tours of the laboratory of hydraulics of DICAR, to teach students about the experimental methods used for the physical modelling of coastal problems;

-field visits at building sites of maritime and coastal works and/or at the premises of public or privaty bodies involved in the coastal management (Port Authorities, Technical Offices, PEs, etc.).
