### Objectives

Knowledge of the basic hydrological processes, their relationships and their importance according to the evaluation purposes of the course.
Basic elements of Statistics and Probability Theory.
In more specific terms:
1) extreme hydrological events (intense rainfall, floods) 2) resource availability for uses (drinking, irrigation, etc.).
The students will be able to quantitatively evaluate the main hydrological processes: evaporation, evapotranspiration, infiltration, surface runoff ...
and the relative hydrological quantities involved.
The course will provide the ability to evaluate and estimate extreme hydrological events of precipitation and runoff with assigned probability of occurrence (return time) both through the calibration of a probabilistic distribution with observed data, and by applying the probabilistic curves already obtained for Sardinia.
Moreover, it will provide the ability to apply inflow-runoff transformation models for the estimation of flood flows (event modeling) and water resources (extended time modeling).
The second part of the course will be devoted to
Statistical analysis of the sample series.
Statistical indexes of position and dispersion evaluation.
Main probabilistic distributions will be examined.
Check the statistical hypotheses will be examined

N. 8 EXERCISES on topics covered

### Teaching Methods

The course is developed in 80 hours of lectures held in the classroom and during which both theoretical aspects and numerical exercises on the topics covered will be developed.
It is believed that about 50 of the course hours will be devoted to lectures and 30 hours to exercises.
During the course there will be a visit to the laboratory at the Hydraulic Engineering section to illustrate the functioning of some measuring devices.
The exercises will examine a specific hydrographic basin on which the hydrological elaborations will be developed.

### Verification of learning

During the course, checks are planned on the progress of the exercises. However, no intermediate test is foreseen.
The final exam consists of an oral test in which the critical knowledge of theories, methods and tools covered in the course will be verified.
The final report of the exercises will also be examined.
The student's evaluation starts with an oral test that usually develops on three questions concerning the main topics covered in the course.
The student will have to demonstrate that he has acquired the knowledge and the ability of critical reasoning of theories, methods and tools covered in the course.
The score of the exam is attributed by a mark expressed in thirtieths according to the following rules: sum of the evaluation of the 3 questions and of the evaluation of the exercise papers.
In assessing the exam, the determination of the final grade takes into account:
1) Knowledge of the topic; 2) Critical reasoning ability; 3) Use of an adequate technical-scientific language; 4) Ability to relate the topics covered in the course and used in the elaborations conducted in the exercises.

### Texts

The slides projected in class are made available on the teacher's website.
The general reference text is: Technical Hydrology - U. Moisello - ed .: La Goliardica Pavese.
In addition, students will be given the opportunity to find other material reported during the course and downloadable from the teacher's website
