The fundamental objective of the course is to provide basic methodological tools to understand the main processes related to the world of water engineering, going from the management of "good" waters (surface and pressurized water networks) to that of "bad" waters (linked to the concept of hydrogeological risk)

(syllabus)
PART 1: general concepts of Hydraulics. Hydrostatic: pressures and Stevino's law. Hydrodynamics: piezometric heads and total heads, Bernoulli's theorem, flow rate, continuity principle, types of movement, load losses and related formulas, verification and design of channels and pipelines. Pumping systems: general information, design problems, types of pumps. General concepts of foronomy PART 2: general concepts of Hydrology. The hydrological cycle and its components. Description of the main hydrological quantities: temperature, precipitation, flow rate. The Hydrological Annals. Precipitation measurement: the pluviometer, the pluviograph, the Thiessen polygon method. Measurement of flow rates: direct measurements (flowmeters) and indirect measurements (rating curves). Description of a river basin. Description of river floods. Hydrogeological risk. Definition of design hydrograph. Surface and deep flow. Identification of the two components of the design hydrograph. Elements of hydrological statistics. Overview of the main distributions used (Normal, Gumbel, Exponential). Return Time of a hydrological quantity. Design and interpretative importance of Return Time. Return time formula. Statistical analysis of the precipitation to be used as input for the definition of the design discharge with assigned return time. Depth-Duration-Frequency Curves and Intensity-Duration-Frequency Curves. Rainfall-runoff modeling. Rational Formula. Concentration time. PART 3: general concepts of Irrigation. Water-soil relationships: physical properties of the soil, filtration motions in saturated soil, wells and water tables. Water-plant relationships: generality, evapotranspiration and calculation methods, irrigation parameters. The irrigation of the land: by submersion, by compartments, by sliding, by artificial rainfall, micro irrigation, mechanized irrigation.

Far conoscere la tecnologia delle macchine agricole motrici nei suoi aspetti costruttivi, funzionali e operativi. La costituzione delle macchine agricole (motori endotermici, trasmissioni meccaniche ed idrauliche, pneumatici, organi di guida e di controllo, sistemi di collegamento attrezzi, sicurezza delle macchine, ergonomia). Il corretto impiego delle macchine agricole (aderenza, controllo dello slittamento, costipamento del terreno, misura dei tempi di lavoro e delle perdite, rendimenti di campo, costi di esercizio, analisi costi-benefici). La certificazione e omologazione delle macchine agricole.
