Learning objectives
The course aims: (1) to provide the scientific basis of hydraulics, with particular attention to the properties of liquids, the statics of fluids and the laws governing the water movement in open channels and in pipelines, (2) to provide concepts and procedures concerning the quantification of plant irrigation requirements, the irrigation techniques and materials, and the irrigation scheduling, (3) to apply theoretical arguments to the verification and the hydraulic design of basic infrastructures and irrigation systems.
Expected learning outcomes
The student acquires the basic knowledge to address and solve hydrostatic, hydrodynamic and water flow problems in open channels and pipelines, as well as problems of irrigation planning and scheduling. Moreover the student acquires the ability to apply the theoretical concepts to the verification and the hydraulic design of basic infrastructures, as well as to the design and the management of irrigation systems.
Course syllabus and organization

Single session

Responsible
Lesson period
Second semester
The lessons and the exercises will be held on the Microsoft Teams platform and can be followed both synchronously on the basis of the first semester schedule, and asynchronously because they will be recorded and left available to students on the same platform.
The program and reference material will not change.
The written and the oral exams will take place using the Microsoft Teams platform.
Course syllabus
The course is divided into two parts: Hydraulics and Irrigation
For the Hydraulics part, the program is concerned with the fundamentals of hydrostatics, hydrodynamics (only for uniform water flow in pipes under pressure and open channels), and foronomy.
For the Irrigation part, the program illustrates the main processes of the soil hydrology, particularly stressing the issues related to the agricultural hydrology, such as the soil water content dynamics, the soil water balance in the root zone, and the irrigation scheduling. Specifically, the program provides notions about: crop irrigation requirements, irrigation methods, quantification of the irrigation amounts, irrigation scheduling, main components of the irrigation systems (sprinkler and drip irrigation), basic knowledge for the hydraulic design of irrigation systems (sprinkler and drip irrigation).
The program also includes Exercises showing the application of the theoretical notions, by solving exercises on the hydraulic design of simple systems, the estimate of crop irrigation requirements, the irrigation planning and scheduling, the design of irrigation sectors
Prerequisites for admission
No prior knowledge is required
Teaching methods
The course includes Lectures (4 CFU) and Exercises (1CFU). In particular, the Exercises consist in solving problems on the hydraulic design of simple systems, the estimate of crop irrigation requirements, the irrigation planning and scheduling, the design of irrigation sectors
Attendance is strongly recommended

Assessment methods and Criteria
The exam consists of a written test and an oral test.
The written test (lasting two hours) consists in solving two exercises (one exercise related to the Hydraulics part, and one exercise related to the Irrigation part); the type of exam exercises is the same as those solved during the Exercises lessons. The resolution of the exam exercises requires understanding the problem and ability to apply the knowledge acquired. During the written test, only the formulary provided by the teacher (the same used for the exercise lessons) can be used.
The outcome of the written examination is expressed in thirtieths, and mainly depends on the correctness of the resolution method adopted and on the clarity in its application, as well as on the ability to assess the results obtained; secondly, the correctness of the calculation is considered. The outcome of the test is communicated on the notice board of the Ariel site of the course
The oral examination consists in the discussion of the written exam paper, and in some in-depth questions on the topics referenced in the written examination
