Course objectives: the fundamental objective of the course is to provide the fundamental, basic methodological tools to understand the main processes linked to the world of water engineering, moving from the management of "good" water (hydraulic networks to free surface and under pressure) to that of "bad" waters (linked to the concept of hydrogeological risk). b) Expected learning outcomes: 1) Knowledge and understanding. Know the basic structure of most systems related to water engineering, both at the verification and design level. 2) Ability to apply knowledge and understanding. Learning of the basic tools necessary for the analysis of the main processes related to water engineering. 3) Autonomy of judgement. Knowing how to identify the key variables for the evaluation of most systems related to water engineering, both at the verification and project level. 4) Communication skills. Ability to transfer at a level of knowledge what has been learned during the design and verification phase of the main systems related to water engineering. 5) Learning ability. A condition for success in learning is the ability to know how to analyze in technical terms the main processes linked to the world of water engineering.

LEARNING OBJECTIVES Knowledge and Understanding The course aims to provide students with the theoretical knowledge, analytical tools and organisational instructions related to agricultural machinery technology in its constructional, functional and operational aspects. Students are expected to acquire the necessary elements for the knowledge of the constitution of agricultural machinery (endothermic engines, mechanical and hydraulic transmissions, tyres, driving and control organs, implement connection systems, machine safety, ergonomics) and the correct use of agricultural machinery (grip, skid control, soil compaction).
Applied Knowledge and Understanding The course aims to foster the student's acquisition of knowledge and understanding such as to - Understand the elements underlying the correct choice and use of an agricultural machine; - Design suitable work sites, both from the point of view of the forces involved (tractor-soil interaction) and from that of safety; - Define the economic aspects in the choice of the most suitable model for the farm's needs
Autonomy in Judgment The course aims to develop students' autonomy of judgement, such as: - Knowing how to choose the tractor according to the forces to be exerted; - Making analyses on the economic viability of machines; - Conducting research on models on the market and being able to understand their technical aspects.
Communication Skills The aim of the course is also to enable the student to develop specific skills through individual work with a ppt presentation on a particular agricultural machine model of the student's choice. The illustration in the examination trains the student in public presentation.
Learning Skills The course is designed to promote knowledge of the theoretical foundations and applications of physics (mechanics and thermodynamics) to modern agricultural machinery, knowledge that can be used in both professional and scientific activities. The knowledge will also be usable for understanding the technological applications underlying modern production systems.
