Learning objectives
An understanding of rainfall, runoff, evapotranspiration and water dynamics in soil and groundwater is essential for those involved in the science, engineering or management of land and environment. This module provides a conceptual and quantitative understanding of hydrology, as a basis for applied studies of water use in agriculture, water tresources conservation and flood protection.An understanding of rainfall, runoff, evapotranspiration and water dynamics in soil and groundwater is essential for those involved in the science, engineering or management of land and environment.

The course aims to provide the basic knowledge of hydrology necessary to address problems of water use for irrigation and of flood protection of the territory, in addition to elements of management of irrigation and flood protection infrastructures. CFU. 1.The hydrological cycle and the fundamental hydrological processes. Precipitation. Interception. Evaporation and transpiration. Runoff. Flow in unsaturated and saturated soil. River flow. The hydrological balance equation. The river basin. Instruments and methods and for measuring hydrological variables. CFU. 2. The water balance of the soil-vegetation-system. Calculation of crop water requirements and scheduling of irrigation. The rainfall-runoff transformation. The rational method and the kinematic method for the estimation of peak flow and flood hydrographs. Sources of hydrological data. CFU. 3. Elements of statistics and probability distributions. Extreme hydrological events. The return period. Elements of statistical analysis of hydrological variables. Estimation of the Intensity-Duration-Frequency curves from observed rainfall timeseries. CFU. 4. (tutorials) Calculation of crop water requirements and scheduling of irrigation with the FAO-paper56 method. Estimation of the time pattern of the total irrigation supply to a district with multiple crops and non-uniform soils. Estimation of the peak flow in a small basin with the rational and kinematic methods and through the direct analysis of observed discharge timeseries.
