OVERVIEW

The HYDRAULICS course is the first course in Fluid Mechanics that students encounter as part of the Civil and Environmental Engineering degree programme. The course is divided into two modules of 60 hours each for a total of 120 hours and provides 6 training credits for each module for a total of 12 training credits.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide the fundamentals of the motion of free-surface fluid flows and the tools for calculating steady-state motion in river channels, and flood wave propagation.

AIMS AND LEARNING OUTCOMES

The course aims to provide the student with the following operational skills:

• Calculation of stationary free-surface current profiles.

The aim of the course is to provide the theoretical tools necessary to understand the fundamental concepts of fluid motion and, at the same time, to translate these concepts into application tools that enable the student to acquire the above operational skills.

PREREQUISITES

None.

TEACHING METHODS

The course consists of 60 lecture hours, of which 36 theory and 24 practical hours. The concepts that are gradually developed in the theory hours are used during the practice hours for application to cases of engineering interest.

Lessons will be delivered in the classroom.

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.

SYLLABUS/CONTENT

Free surface flows - calculation of distributed resistances in steady and uniform motion currents. The possible states of free surface currents, the critical depth. Stationary and non-uniform currents, the profile equation. Localised phenomena: hydraulic prominence, inlet, outlet, section narrowings. Notes on wave propagation in free surface currents, the kinematic wave model.

EXAMS

EXAM DESCRIPTION

The examination comprises one written test and a final oral examination. The written test covers the application topics dealt during the course. Students will be admitted to the oral examination after obtaining a score of at least 18/32 in the written tests. Two written interim tests are scheduled during the course. Each intermediate test is considered passed if the student has obtained a mark of at least 15/32. The student is exempt from taking the written examination if he/she has passed both midterm examinations with an average mark of at least 18/32.

ASSESSMENT METHODS

The written tests, both intermediate and final, focus on application exercises relating to the topics covered in class, with particular reference to the topics developed during the exercise hours and the operational skills stated in the training objectives. The written tests include exercises relating to the qualitative and quantitative determination of stationary motion profiles in free-surface currents. The final oral examination, which the student accesses after passing the written tests, is aimed at ascertaining the understanding of the theoretical knowledge acquired by the student. The examination thus focuses on the formulation of the problem of fluid motion and the consequent demonstrations, which allow the formalisation and derivation of the application tools already used in the written tests.

Working students and students with certified DSA, disabilities or other special educational needs are advised to contact the lecturer at the beginning of the course in order to agree on teaching and examination methods that, while respecting the teaching objectives, take into account individual learning methods.
