AIMS AND CONTENT

LEARNING OUTCOMES

Il modulo affronta il dimensionamento e la realizzazione di impianti idraulici e manufatti per il controllo e gestione delle acque in ambiente urbano e sul territorio. Fornisce strumenti concettuali/operativi per il dimensionamento e realizzazione di opere idrauliche per il controllo degli scarichi di origine antropica, la laminazione delle piene e ripartizione delle portate, degli impianti di pompaggio dell’acqua e stazioni di sollevamento.

AIMS AND LEARNING OUTCOMES

After attending the module "Design of Hydraulic Systems and Infrastructures", students will be able to design and dimension hydraulic works for water flow diversion and partitioning, storage tanks and storage areas, as well as pumping stations by knowing the main characteristics and hydraulic performance of centrifugal pumps, the various types of impellers, the risk of cavitation, the contemporary use of multiple pumps and the dimensioning of the pump sump and the associated damping and vortex prevention devices.

Students will develop the capability of managing their social interactions with a collaborative attitude and adopting constructive communication processes. They will develop decision-making autonomy, a collaborative attitude, the ability to manage information and materials, to negotiate solutions and to treat the uncertainties.

TEACHING METHODS

The module is organised in a series of frontal lectures in the classroom, including practical exercises on the dimensioning of simple design cases, and in a laboratory experience about the dimensioning of a lateral spillway.

Part of the module will be organised by dividing students in groups, to whom a design problem is assigned involving the dimensioning of a lateral spillway by means of software tools and experimental validation in a laboratory test, to be presented in the form of a technical report. In the last scheduled hours of the module, each group will be asked to illustrate the obtained result to the class; after the presentations, a discussion will be open addressing the specific cases encountered by each group and the adopted technical solutions.

Working students and students with learning disorders ("Disturbi Specifici di Apprendimento", DSA), disability or other certification of special educational needs are advised to contact the teacher at the beginning of the course to agree on teaching and exam methods which, in compliance with the teaching objectives, take into account individual ways of learning.

EXAMS

EXAM DESCRIPTION

The student knowledge of the course programme will be assessed by means of an oral exam. The discussion of the group work will be an integral part of the exam.

Students with learning disorders ("Disturbi Specifici di Apprendimento", DSA) will be allowed to use specific modalities and supports that will be determined on a case-by-case basis in agreement with the delegate of the Engineering courses in the Committee for the Inclusion of Students with Disabilities.

ASSESSMENT METHODS

For the report on the dimensioning of a lateral spillway based on the laboratory experience, the assessment of the student qualification is performed by evaluating the correctness of the solution provided for the assigned group work, the theoretical basis exploited and the experimental results. The interaction with other students within the group and the whole classroom will be also considered, as well as the ability to discuss technical-design aspects based on the questions posed by the teacher.

For the oral part, the assessment is performed based on the correctness of the exposition and discussion of design and/or conceptual topics concerning content of the whole course.
