Learning objectives

Knowledge and understanding:
At the end of this course the student will complete his knowledge in hydraulics and hydrology with that related to hydraulic plant design and will be owner of the overall concepts at the basis of the design of the main hydraulic plants not studied in other courses. The student will have examined in depth the different types of hydraulic machines and their use, he will be aware of the main problems related to realization and operation of hydroelectric power plants, he will be in possess of the concepts at the basis of the design of pressurized and open-channel irrigation networks.

Applying knowledge and understanding:
At the end of his study the student will be able to design different types of hydroelectric power plants in their different aspects: water supply works definition, choice of the scheme, sizing of penstocks, regulation, art works and special parts. The student will be capable of choosing and sizing the hydraulic machines proper for the case of interest and will be able to design operation and regulation of hydroelectric groups. For what concerns the irrigation plants the student will be capable to preliminary design irrigation networks on the basis of watering methods and schemes.

Making judgments:
By the end of the course, the student should own the instruments to identify and solve the main problems related to the design and operation of the hydraulic plants studied and of those that will be encountered in the future profession.

Communication skills:
At the end of the course the student will be capable of a correct use of language at least for what concerns the technical nomenclature proper of the course.

Learning skills:
The final lessons and technical tours have the main aim of introducing the student into the more recent develops concerning the design and realization of traditional, small and micro hydroelectric plants. The students should be in possess of the basic knowledge of the discipline to carry on, in the future, a personal in depth investigation of the topic.


It is useful to have attended the course of Hydraulics.
It is useful to have attended the course of Hydrology.
It is useful to possess a basic knowledge of Windows and Excel.

Teaching methods

Slides will be used to convey the most important messages of the theory lectures. A series of laboratory exercises at the pc will be developed for the application and personal development of numerical codes devoted to the study of the problems related with hydroelectric and irrigation plants. Spreadsheets and more complex computing tools will be adopted.
At the end of the course in-depth lessons related to some of the main topics will be developed. Technical visits to some hydroelectric plants will be organized. Every student will develop the design of a high head hydroelectric plant under the supervision of the professor.

Assessment methods and criteria

The examination is based on an oral exam and on a written report presenting the preliminary design of a high head hydroelectric plant. The examination is weighted as follows: 60% oral exam (theory questions, application of theory also to original problems and speaking ability), 40% written report discussion.

Other information

Lecture attendance is highly recommended.
