- Objective of the course: to introduce students to the study of the main processes of fluid mechanics aimed at the reading of land accommodation and land improvement projects. The most important hydrostatic and hydrodynamic phenomena will be illustrated and formulated, both for surface waters and for underground waters, in the context of the evaluation of water resources, of water supply and of the reclamation. At the same time the student will be introduced to the analysis of the problems and to the resolution of the calculations for designing and testing the pipelines (long and short), the open canals, the drainage systems and the wells

- Learning verification modality
- Oral exam aimed to verify the student knowledges, his discussion capacity, his applicative capacity related to solve hydraulics problems. The exam consists in a discussion of about 30-45 minutes on 3 questions at least. The questions are related to different topics (hydrostatics, hydrodynamics, soil water retention) of the program illustrated during the lectures.
