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.

Expected learning outcomes
The aim of the course is to give a solid method of hydrologic analysis and the fundamental tools and techiniques for the analysis and solution of hydrological problems, including irrigation water demand estimation and flood protection.The aim of the course is to give a solid method of hydrologic analysis and the fundamental tools and techiniques for the analysis and solution of hydrological problems, including irrigation water demand estimation and flood protection.

Course syllabus
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. Estiamtion 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.
