Course description

The aim of the course is to analyze the role of the main hydraulic works at the service of urban communities, illustrate their characteristics and main artifacts, provide the necessary elements for their design, implementation and management, making the student able to draw up a preliminary project of such systems.

Learning outcomes (compared to the Dublin descriptors):
- Knowledge and understanding:
At the end of the course the student will have integrated their basic knowledge on the hydraulic behavior of free surface networks and pressurized networks. The student will be able to know and understand: the main functioning schemes of aqueducts and sewer networks; the criteria for sizing the elements constituting the water and sewerage networks, to acquire sensitivity with respect to the design criteria that include the management problems.

- Ability to apply knowledge and understanding
At the end of the study path the student will be able to apply design methods and criteria in the case of a consortium aqueduct, a water distribution network and an urban sewer. It will also be able to use specific software for the hydraulic simulation of the systems.

- Autonomy of judgment
The student must be able to compare the different calculation models used, identify and define the most suitable indicators and descriptors to evaluate the data and results obtained; finally, it must be able to identify possible and potential connections between the various aspects of a topic and / or a problem.

- Communication skills
During the course the student will have to collaborate within a working group, defining objectives, activities, tools to be used in the design of an aqueduct network and a sewer network. He must be able to present the design documents drawn up during the course, correctly using a technical-scientific language. Finally, it must be able to illustrate to a non-expert public the preliminary design of a hydraulic infrastructure.

- Learning ability
The student must be able to integrate the acquired knowledge on the functioning of the main hydraulic infrastructures and on the sizing criteria of these works through the consultation of texts and publications available on the teacher's website and through the use of Web search tools and dedicated software.

Prerequisites

You must have acquired the following knowledge provided by the Hydraulics course:

- Elementary concepts of fluid and its properties. The continuous fluid. Forces acting on a continuous fluid.
- The state of tension in a fluid at rest, cardinal equations of statics, static thrusts on flat surfaces and humps.
- The state of tension in a fluid in motion. Scheme of ideal fluid and Bernoulli's theorem.
- Fluid currents: definition and characteristic quantities. The principle of conservation of mass and quantity of motion for a current.
- The currents under pressure: The calculation of the resistances distributed in the currents under pressure in uniform motion.
- The free surface currents: the calculation of the resistances distributed in the currents in uniform motion. Possible free surface current states, critical depth. Stationary and non-uniform currents.

Teaching Methods

The teaching activity of the course is organized in lectures, individual and group work with the drafting of three project documents that will cover an external aqueduct serving one or more municipalities, a water distribution network and a drainage network.

Learning assessment

The exam takes place orally and involves a discussion on the design projects produced and on the theoretical and calculation aspects treated during the course. The student must demonstrate full mastery of the tools used to carry out the exercises and be able to justify the solutions adopted. It must also demonstrate that it has understood the formal, theoretical and practical aspects contained in the design procedures taught.
