    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 difraction phenomena and the possible wave breaking. The morphodynamic phenomena generated by sea waves will be also described.
    
     

    TEACHING METHODS

    Frontal lectures

    Working students and students with SLD, disability or other special educational needs are advised to contact the teacher at the beginning of the course to agree on teaching and examination methods that, in compliance with the teaching objectives, take into account their individual needs
