Learning objectives
The aim of the course is to complement the basic hydrologic concepts
(acquired in the course “Idrologia”) and to develop the main topics
concerning basin management plans, mainly with reference to flood
defence. To complete also the knowledge of flood control measures in
mountain streams and in plain rivers.
Prerequisites
Hydraulics, Hydrology.
Course unit content
Hydrology complements. Flood volume estimation; Synthetic Design Hydrographs (SDH) for gauged and non-gauged sections.
Dam and land protection regulations. River floodways. Torrent settlement.
Flood routing: Hydrologic unsteady flow models: theory, parameter calibration and application of Muskingum method. Hydraulic unsteady flow models: De Saint Venant hypotheses and equations; initial and boundary conditions for sub- and supercritical flows; methods of solution: characteristics, finite difference (explicit and implicit), Courant-Fredrichs-Levy stability criterion.
Sediment grain size and properties. Threshold of sediment motion: Shield’s diagram. Bed load estimation formulas. Check dams for sediment control. Local scouring around bridge piers and abutements.
Fish passes. Types of fish passes, design and dimensions.
Rivers settlement and floods control. longitudinal (levees, bank protections) and transversal (check dams, sills, groynes) hydraulic structures.
Flood control. Structural measures: land reforestation, river embankments, stream corrections, canal spillways, diversions, reservoirs, flood control reservoirs. Non-structural measures: flood hazard maps.
