Finalità
The course deals with the hydraulic design of hydropower plants, artificial drainage networks and irrigation plants, both pressurized and open-channel.

Programma
Adduction main pipelines: gravity and lift schemes, hydraulic transients control, charge and compensation basins, oscillatory wells.
Hydropower plants: basic schemes, plants with and without flow regulation, forced pipelines, interception, regulation and security valves, plant project and design.
Hydraulic turbines: definitions, classification and functional features, fundamental equation of hydraulic turbines, similarity and characteristic rounds number, characteristic curves, problems in machine operation.
Hydroelectric power plants: operating programmes, automatic regulations of hydroelectric groups, pressure control and escape velocity of groups.
Irrigation plants: scope and definitions, relationships between soil, climate and crops, field water supply, pressurized and open-channel irrigation networks, watering methods and schemes. Outlines of drainage networks: hydrological references, scope, hydraulic design.

Attività d'esercitazione
Four numerical exercises are provided, three of which are compulsory: 1) mass oscillation computations in hydropower plants, 2) waterhammer computations in hydropower plants, 3) design of pressurized irrigation plant, 4) design of drainage network. The numerical analyses entail the PC general knowledge and the use of specific tools to be provided by the Course. The exercises should be completed and produced al least 7 days before the final examination, in paper and magnetic form.

Modalità d'esame
In order to take the final examination, the numerical exercises must be produced 7 days in advance.
The examination splits into two parts: A) discussion on exercises and practical test with their computational tools ; B) questions about the course programmein written or verbal form (student’s choice).
