Knowledges in Hydraulics, Hydrology, Hydraulic Engineering are required

The course aims to provide knowledge and deepening on specific issues regarding the hydraulic constructions in urban areas, focused on water distribution systems and urban drainage systems. The course is divided into two modules: “Hydraulics networks” and “Urban drainage”. At the end of the “Hydraulics networks” module the student must know the basic concepts regarding the steady flow in the pressurized systems and their mathematical modeling. The student must also be able to carry out the design and the analysis problems of water networks in different topological configuration and feeding conditions. At the end of the “Urban drainage” module the student must have conceptual and practical knowledge related to the most advanced developments in the field, with particular reference to the quantitative and qualitative control of the meteoric waters discharge and modern construction techniques and rehabilitation of sewer networks.

“Hydraulics networks” (Prof. C. Ciaponi)
Introduction: pressurized pipe systems characteristics, long pipes, working under negative pressures, design and verification problems of long pipes.
Hints related to pumping systems: characteristic curves, NPSH, maximum suction lift, verification and design problems.
Pipeline systems: definitions and topology, schematic delivery.
The hydraulic analysis of pipeline systems: system of equations; numerical methods for the resolution; hydraulic verification of networks with complex feeding systems (several tanks and pumps).
Performance analysis of water systems: performance indicators and their quantification.
The design of pipeline systems: design problem; solution methods; design with linear programming techniques.
Software application: teaching is supplemented by exercises during which the students have to design and verify some water distribution networks, through the application of software given by the teacher.

“Urban drainage” (Prof. S. Papiri)
Sediment control in sewage systems.
Stormwater runoff: quantitative quality and management aspects.
Retention tanks: legislation, design.
Stormwater tanks: legislation, types, equipment.
Diagnosis of the functional problems for the existing sewer networks.
"no-dig" technologies for the rehabilitation of existing sewers.
"no-dig" technologies for the sewage construction.

Lessons (hours per year in the classroom): 36
Exercises (hours per year in the classroom): 18

Teachers will give documentation on the topics covered in the course. Further investigations will be possible through the consultation of bibliographical references. The lesson slides and the exercises solutions of "Hydraulic Networks"module are available on KIRO Platform

The “Urban drainage” module requires an oral test while the “Hydraulics network” module requires a written test. The average of the two votes (if both equal or greater than 18/30) will be the final vote. The positive result of one of the two tests, if accepted by the student, will be used for the final result even for subsequent exam sessions, once the second test will be passed.
