CODE 98074 2024/2025 5 cfu anno 2 ENVIRONMENTAL ENGINEERING 10720 (LM-35) - GENOVA ICAR/01 English GENOVA 1° Semester Questo insegnamento è un modulo di: AULAWEB

## AIMS AND CONTENT

### LEARNING OUTCOMES

The course is aimed at introducing the student to the hydrodynamics and morphodyanics of the coastal region

### AIMS AND LEARNING OUTCOMES

```The course is aimed at making the student capable of formulating and solving the problems related to the propagation of sea waves from the offshore region to the coastline considering refraction and diffraction phenomena and the possible wave breaking. The morphodynamic phenomena generated by sea waves will be also described.

```

### TEACHING METHODS

Frontal lectures.

Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Federico Scarpa (federico.scarpa@unige.it), the Polytechnic School's disability liaison.
