Learning objectives
Knowledge and ability to understand:At the end of the course of the course the student will have to know the main theoretical aspects for the study of coastal processes.Skills:The student must be able to describe the physical process with the use of mathematical analysis; to identify the process parameters by separating them from the variables; to solve the application cases, carrying out checks to the advantage of security.Autonomy of judgment:The student must possess the tools to critically evaluate the applicability of the acquired models or the need to resort to more advanced and detailed models.Communication skills:The student must possess the ability to clearly present the results of the analysis, both orally and in writing, also through the use of tables and graphs.
Prerequisites
Hydraulics, Differential analysis, Geometry, Rational Mechanics, Physics.
Course unit content
The course provides the student with advanced concepts of Hydraulics and Fluid Mechanics in coastal processes. The student is able to solve some technical problems of Environmental Hydraulics, with the application of conceptual models, numerical and physical models. Five numerical exercises are planned in order to concretely demonstrate some aspects of the topics covered. A visit to the Hydraulics laboratory is scheduled.

Teaching methods
The theoretical part of the course will be illustrated through lectures using a tablet PC connected to a video projector, used as an electronic board. The lectures will be complemented by educational videos. A part of the course is reserved for analytical and numerical exercises.
Assessment methods and criteria
The examination is based on an oral exam. Three questions for a maximum 0.5 h.Evaluation elements: theoretical questions (knowledge and understanding), 50%; application of the theory or application examples (skills, independence of judgment), 35%; exposure properties (communication skills), 15%.
The vote is in thirties.
Other information
Lectures attendance is highly recommended.
