Learning outcomes of the course unit
The course presents the basic knowledge about water diversions with and without flow regulation. The main types of dams are rewieved, according to the Regolamento Dighe. Weirs and floodgates are presented. Some basic information is given about fluvial and coastal structures concerning inland and marine navigation.
Hydraulics, Hydrology, Geotechnics, Structural engineering
Course contents summary
General pur pose of hydraulic structures. Water resource concept. Water uses examined in the course: A) Municipal water supply, B) Agricultural supply, C) Industrial (hydropower generation), D) Transport and Navigation.
A-B) Municipal and Agricultural water supply -: 1) Dams and Reservoirs, 2) Diversions and Offtakes, 3) Interceptions
1) Dams and Reservoirs: Regolamento Dighe, stresses over retenrion structures, design criteria, building, management and maintenance of dams. Gravity dams, arch dams, other concrete type dams. Earth dams, rockfill dams.
2) Diversions and offtakes: fixed weirs, movable floodgates,. Piping and heaving, saturated-unsaturated flow in porous media (analytical and empirical solutions). Levees, desilting basins, outlets.
3) Interceptions: spring interception, groundwater withdrawal.
C) Industrial use : hydropower generation : short outline
D) Transport and Navigation1) Inland navigation : features of inland transport, international treaties on inland navigation. Natural waterways: canalization and regularization of waterways, Fargues laws. Man-made waterways: design criteria and linkage to the natural network. Subsidiary works: locks, canal-bridges, pumping plants.2) Sea NavigationShort account on winds, waves, currents, tides. Phenomena of wave motion: breaking, shoaling, rifraction, diffraction, reflection. Ports: piers, wharfs, docks.
Four numerical exercises are provided, two of which are compulsory: 1) Stress analysis of a gravity dam, 2) Stress analysis of an arch dam, 3) Regulation analysis for a multi-purpose reservoir, 4) Statistical analysis of river diversion without flow regulation.

In order to take the final examination, the numerical exercises must be produced 7 days in advance.The examination splits into two parts: A) discussion on exercises and practical test with their computational tools ; B) questions about the course programmein written or verbal form (student’s choice).
