Corso:
Laurea Magistrale in
Ingegneria per l'ambiente e il territorio (cod. 8894)
Valido anche per Laurea Magistrale in Civil Engineering (cod. 8895)
Conoscenze e abilità da conseguire
Il corso fornisce una conoscenza teorica avanzata nonché strumenti applicativi per il dimensionamento di grandi dighe, con particolare enfasi sulla stima delle forze agenti, sui manufatti idraulici, sulla prevenzione e l'identificazione di perdite e sul dimensionamento di grandi impianti idroelettrici. Gli studenti acquisiscono esperienza nell'ambito della gestione di grandi opere idrauliche, con attenzione anche all'impatto ambientale. Verranno infine analizzati alcuni casi studio relativi a grandi dighe costruite recentemente.
Contenuti
Requirements/Prior knowledge
A prior knowledge and understanding of basic hydraulics and hydrology is required to attend with profit this course. Advanced Hydrosystem Engineering (or any similar courses about Water Supply and Urban Drainage) is a preferential pre-requisite.
Fluent spoken and written English is a necessary pre-requisite: all lectures and tutorials, and all study material will be in English.
Course content
Introduction to water resources engineering: design approaches; water availability and consumption; water-control and water-use systems; water use; systems of unit; sustainability (2 hours)
Review of hydrologic processes: hydrologic cycle; world water distribution; hydrologic balance; rainfall (measurement, statistics, spatial interpolation, distribution, regimes); climatic variability; runoff (measurement, distribution, regimes); urban areas (3 hours)
Water distribution systems; review of principles of fluid mechanics: physical properties of water; mass and energy conservation; frictional and fitting losses; energy and hydraulic grade lines. Exercises (4 hours)
Pumps: types of pumps; performance of pumps (performance curves and specific speed); pump selection (characteristic and system curves); operating point; cavitation and limits on pump location; multiple pump systems. Exercises (7 hours)
Dams and reservoirs: principal parts of a dam; types of dams; additional classification of dams; types of dam spillways; reservoir storage; sediment accumulation. Exercises (3 hours)
Gravity dam design: general design considerations; loads; stability analysis. Exercises (3 hours)
Examples of dams: Three Gorges Dam, Bilancino Dam, Montedoglio dam (3 hours)
Dam failure: large dams and failure; notable dam failures across the globe; basics of dam breaking modeling; climate-induced failure of aging dams (8 hours)
Reservoir: determination of the design volume and exercises; management for irrigation & hydropower production and exercises (6 hours)
Water for Hydroelectric Generation: hydropower production and demand; types of hydropower plant; turbines; energy potential, flow-duration method). Exercises (9 hours)

Metodi didattici
Theorical lessons (in presence/online) and computer-based exercises on key topics.
Lessons attendance is a key requisite to acquire a detailed knowledge. Students should attend all lectures or obtain the notes from their colleagues when absent.
Modalità di verifica e valutazione dell'apprendimento
Achievements will be assessed by means of a final written examination. This is based on an analytical assessment of the "expected learning outcomes" described above. The exam is composed by:
-
3 open questions
-
2 exercises
To obtain a passing grade, students must demonstrate a knowledge of the key concepts of the subject and a comprehensible use of technical language.
Higher grades will be awarded to students who demonstrate an organic understanding of the subject and a good ability for critical application, without any numerical/anlytical error.
Failing grade will be awarded if the student shows knowledge gaps in key-concepts and logic failures in the analysis of the subject.
Strumenti a supporto della didattica
Use of powerpoint and blackboard/tablet. Powerpoint presentations and videos of the lessons will be available on virtuale.unibo.it.
