Hydraulics, hydraulic constructions and hydrological risk

Learning objectives

The teaching aims to introduce the hydraulic and hydrological principles commonly used in the design, verification and management of hydraulic constructions aimed at the use of water resources and the hydraulic protection of the territory.
