- The course examines hydroelectric power and hydraulic machinery, irrigation methods and structures and drainage systems, design of hydroelectric machinery and of irrigation methods.
The main expected learning results will be:
•knowledge and understanding of the hydroelectric power and hydraulic machinery, irrigation methods and structures and drainage systems, monitoring network for hydrometeorological quantities;
•skill to select and apply proper hydroelectric power system in order to optimize energy production and to design irrigation and drainage systems. - Prerequisites
- In order to deeply understand mathematical models involved in the program of the course and to reach the expected learning results the following elements are required:
•Mathematical analysis: analytic functions, differential and integral calculus of functions of single and several variables, partial differential equations.
•Physics and Rational Mechanics: vector calculus, cardinal equations of statics and dynamics.
•Hydraulics: elements of Hydrostatics, open channel flow and pressurized flow.
•Municipal Water Systems: static analysis of underground pipes.
•Hydrology: main components of hydrological cycle (precipitation, runoff, infiltration)and basic hydrological modeling. - Teaching methods
- The course is organized in:
•Face-to-face lessons;
•Practical training;
•Seminars. - Other information
- The main course Water Resources Management and Hydraulic Systems is divided into two coordinated modules: i) Water Resources Management ii) Hydraulic Systems.

- HYDRAULIC SYSTEMS
The exam of the course consists of an oral discussion over the contents of the course program.
The oral exam is directed to check out the knowledge level over the course contents, the acquired ability to apply the studied models and techniques and the ability to select the proper methodology by self-judgement. Furthermore, the oral exam has also the objective to evaluate communication skills and the usage of an appropriate language about the theoretical and practical subjects of the course.
The grade of the exam is certified with the local grade system, which is a number on a scale from 18 to 30.
WATER RESOURCES MANAGEMENT AND HYDRAULIC SYSTEMS
The exam of the course consists of a written test and two oral discussions over the contents of the two parts of the course program, to be performed separately or in the same exam session.
The written exam, lasting 1 hour, consists of the solution of problems related to the water resources management modeling. The test has the aim to prove the ability of understanding the proposed problems and applying theoretical knowledge in order to obtain quantitative results, the skill to elaborate by self-judgment proper remarks, and the capacity to effectively communicate in a written form.
The two oral exams, each one lasting about 45 minutes, are directed to check out the knowledge level over the course contents, the acquired ability to apply the studied models and techniques and the ability to select the proper methodology by self-judgement. Furthermore, the oral exams have also the objective to evaluate communication skills and the usage of an appropriate language about the theoretical and practical subjects of the course.
The grade of the exam is certified with the local grade system, which is a number on a scale from 18 to 30. The exam mark will be provided by a weighted average of the results obtained in the separate tests, with the following weights: written test: 1/6; oral test related to the first part of the course program (Water Resources Management): 1/3; oral test related to the second part of the course program (Hydraulic Systems): 1/2. - Extended program
- The course deals with hydroelectric power and hydraulic machinery, irrigation methods and structures and drainage systems. All these elements are directed to the design of hydraulic infrastructures The course is organized in different units as follows:
Hydroelectric power: thermal versus water power, systems and load, project arrangement, electrical equipment.
Hydraulic machinery: turbines, centrifugal and axial pumps.
Optimal design of branched and looped systems. Irrigation: water requirements, soil water relationships, water quality, irrigation methods, irrigation structures.
Drainage: estimate of flow, land drainage.
