Teaching Methodologies
Oral exposition – used for the presentation of academic contents detailing principles and foundations, illustrated with practical cases, with the support of the projection of video of schematics and images.
Problems of numerical calculation – used for the development of specific reasoning skills for the subject of the curricular unit, also aiming at self-assessment so that the student becomes aware of his/her level of understanding of the subject Field visit – used for presentation and explanation by the teacher of examples of irrigation and drainage systems and equipment, seeking to motivate and encourage the student to study; the visit, in principle, takes place on agricultural grounds of the School. Project – used to develop a work of verification or design of components of irrigation and drainage facilities at the plot level, requiring the integration of theoretical and practical knowledge already acquired
Learning Results
1. Understands the relationship among agricultural production and the environment;
2. Know the basics of irrigation and drainage, referenced to water resources, soil, climate, crop water needs and hydraulic equipment’s;
3. Knows the irrigation methods, criteria of choice and procedures for calculating facilities at the field level;
4. Know the drainage systems and techniques and their design and maintenance criteria.
Program
1. Introduction to water resources management and environmental problems associated with irrigation.
2. Bases of irrigation and drainage: water resources; soil water and usable capacity, infiltration; crop evapotranspiration, soil water balance method, irrigation need and applied hydraulics.
3. Irrigation methods: performance indicators; surface irrigation – characteristics and modernization, water distribution systems, land leveling operation and irrigation process; sprinkler irrigation – types of installation and characteristics, wind problem, calculation of fixed installations; microrrega – types of installation and characteristics, filtration and fertigation, calculation of installations; comparison of irrigation methods.
4. Drainage: drainage benefits, irrigation-drainage ratio, soil characteristics, drainage parameters; surface drainage – factors and techniques, systems maintenance; underground drainage – techniques and drainage materials, sizing and maintenance criteria
