Skills (skills):
- Knowing how to obtain the basic data
- Knowing how to interpret the data available
- Knowing how to process the data available
- Knowing how to choose the system best suited to specific application
- Knowing how to identify the critical points of a system
- Provide guidance on the management of the systems
Behaviors (interpersonal skills)
- To have acquired communication and interpersonal skills to work in group
- Having acquired the skills to operate in an interdisciplinary field - Prerequisites
- In order to understand and know how to apply most of the techniques described in teaching, it is necessary to have knowledge of mathematics and Physics. These knowledge are a prerequisite for the student who wants to follow the course with profit
- Teaching methods
- Starting from the operational and functional aspects of the discipline, anchoring aspects of the technical applications, the course investigates the correlates conceptual and methodological aspects. At the same time a case study will be developed.
- Learning verification modality
- The oral exam consists of a discussion lasting about 45 min aimed at ascertaining the level of knowledge and understanding achieved by students on the theoretical and methodological implications mentioned in the program. The oral exam will also test the ability in communication of the student in thecnichnical language on the topics in theoretical content and design.
- Extended program
- The course is aimed at
- Provide adequate basic knowledge of hydrology and hydraulic function of irrigation and drainage in the planning and design and testing of irrigation and drainage systems;
- Describe and analyze the criteria and techniques of irrigation and drainage planning, design / verification / compliance and facilities management.
