PETROSELLI Andrea
(syllabus)
Part 1: basic concepts of hydraulics Hydrostatics: pressures, Stevin’s law. Hydrodynamics: total head and piezometric head, Bernoulli theroem, flow movement, discharge, continuity principle, types of movement, head losses and empirical formulas for their estimation, verification and design of pipes and channels. Generalities on pumps. Foronomy: orifices and weirs. Part 2: basic concepts of hydrology Hydrological cycle and its components. Description of the main hydrological variables: temperature, rainfall, discharge. Measurement of precipitation: raingauges, radar. Estimation of areal precipitation: the Thiessen polygons. Measurement of discharge: direct and not (stage discharge relationship). Concept of a watershed. Description of floods, of hydrological risk and hydrograph definition (direct runoff and baseflow). Elements of statistical hydrology. Main used distributions (Gumbel, Lognormal, Exponential). Return period of an hydrological variable. Intensity-Duration-Frequency Curves. Estimation of the design discharge: rational formula, concentration time, Giandotti formula. Part 3: basic concepts of irrigation Relationship between water and soil: soil physical properties, infiltration, movement of water into soil. Relationship between water and crops: evapotranspiration, irrigation parameters. Description of the main irrigation techniques (pipes and channels). Drainage of the terrain.

(objectives)
The course aims to introduce the technology of agricultural machinery in its constructive, functional and operational aspects. The setting-up of agricultural machinery (combustion engines, mechanical and hydraulic transmissions, tires, driving mechanisms and control systems, connection equipment, machine safety, ergonomics). The correct use of agricultural machinery (grip, slip control, compaction of soil, extent of work times and losses, performances in field, running costs, cost-benefit analysis). The approval and certification of agricultural machinery.
