1016133 - PORT AND COASTAL ENGINEERING
Teacher: ROSARIA ESTER MUSUMECI
Expected Learning Outcomes
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.).
Required Prerequisites
It would be good to have a background on hydraulics and/or fluid mechanics
Attendance of Lessons
Attendance to classes is strongly encouraged to favor active participation.

Learning Assessment
Learning Assessment Procedures
At least 7-10 days before the date of the final exam, the student must send a draft of the report about the practical excercise on the class topics, printed or via mail. Once revised, the student should bring a copy of the final version of such a report the day appointed for the finals.
During the finals,the student should answer, generally, three oral questions about the topic of the class (refer to the Most frequent questions below).
The evaluation will be based on the:
- quality of the report on practical applications (50%);
- completeness and clarity of the answers to the oral questions (50%).
Active participation to class work will be also accounted for.
Examples of frequently asked questions and / or exercises
Linear wave theory
Dispertion relationship
Wave refraction
Shoaling and breaking
Wave reflection
One-line model of shoreline evolution
