Learning outcomes of the course unit
The course aims to provide an overview of the main hydraulic plant and equipment not discussed in other courses (Hydraulic Constructions, Territorial Hydraulic Protection, Hydraulic Infrastructure). Special consideration is given to supply schemes under pressure, hydroelectric plants, and the main types of open channel systems, for irrigation and reclamation purposes.
Hydraulics, Hydrology, Geotechnics, Construction Science.

The exercise papers must be handed in at least 7 days before the examination to be allowed to sit for the exam that has two parts: A) discussion of the exercises, with possible practical test on the use of the calculation tools used; B) questions on the topics of the course programme in verbal or written form, as preferred by the candidate. The exam includes 4 numerical exercises, of which 3 are compulsory to be chosen from: 1) mass oscillation calculation, 2) water hammer calculation, 3) irrigation network calculation, 4) drainage network calculation. The exercises require the general use of a PC and some specific tools provided in the course.
