72879 - Urban Hydraulic Systems M

Course contents

Recommended Prerequisites

To successfully follow the course, students must possess a good understanding of hydraulics and hydrology, particularly concerning pressure and open-channel flow, hydro-meteorological measurements, and the statistical analysis of extreme events. Additionally, proficiency in using spreadsheets and/or programming languages (Matlab or R) is required.

All lectures, apart from seminars, will be held in Italian. Therefore, comprehension of the Italian language is necessary to successfully follow the course and utilize the provided learning materials.

 

Course contents

Module 1 - WATER DISTRIBUTION SYSTEMS

Components of water distribution systems, characteristics and methods of control.

State of the aqueduct infrastructure, identification of critical issues and interventions. The concept of resilience of water distribution systems.

Monitoring in water distribution systems: Supervisory Control And Data Acquisition and district monitoring systems.

Drinking water demand models and smart meters.

Numerical models of water distribution systems. The building of a numerical model. Steady-state model for numerical analysis on a single and extended period. Numerical model of the quality of distributed water. EPANET 2.2 code.

Design of water distribution systems, sectorization and pressure control.

Efficient management of water distribution systems. Water losses: estimation, control and reduction strategies. Criteria for the management of aqueduct systems in conditions of water scarcity.

Protection of water distribution systems in unsteady-state condition. Hydraulic protection devices and sizing criteria.

The integrated water service and its governance. The tariff method. Indicators for measuring technical quality. Water Safety Plan.

Design of a water distribution system. Using EPANET 2.2 software, students will be guided through the design of a water distribution system. This project aims to solidify the concepts covered in the course program. I twill be analyzed aspects related to distributed water quality, water losses, and sectorization. The project will include a detailed design report.

 

Modulo 2 - URBAN DRAINAGE SYSTEMS

Introduction to urban drainage systems: water management and climate change scenarios.

Design of sewer systems. Wastewater flow analysis. The hydrological cycle in urban areas. Statistical analysis of rainfall observation. Stormwater flow analysis: rational method. Design of drainage systems: pipelines cross-sections and materials, flow velocity bounds. Manholes. Gully pots. Combined sewer overflows.

Storage systems: water quantity and quality problems in urban areas respect to the receiving water bodies and groundwater. Detention and retention ponds and first flush tanks.

Numerical modeling of sewer networks under unsteady flow conditions: the EPA SWMM software.

Green Infrastructures. Sustainable Drainage Systems (SUDS): green roofs, infiltration trenches, permeable pavements, etc.

Sewer inside buildings: disposal of rainwater and wastewater from buildings. Design of systems for rainfall and gray water harvesting.

NO-DIG technologies for the installation and rehabilitation of pipes.

Stormwater management in roads, railways and airports.

Design of a Sewage System. Using SWMM software, students will be guided through the design of an urban sewage system. This project will also involve the sizing and verification of structures such as retention basins, first-flush tanks, and pumping stations. The project will include a detailed design report and some illustrative graphical outputs.

Teaching methods

Face-to-face and online teaching; seminars, practical sessions.

Assessment methods

Learning assessment through: i) final written exam where the student is called to solve short exercises and answer questions on the topics covered in class (students should attend all classes or take notes from colleagues when they are absent) without the help of notes or books; ii) oral exam will assess whether students have achieved the learning objectives, particularly the basic concepts for modeling and designing water supply and sewage systems, along with a discussion of the projects completed.

Passing the exam will be guaranteed to students who demonstrate mastery and operational ability related to the key concepts presented in the course, especially the design criteria used to size hydraulic systems.

Teaching tools

In addition to the reference texts, presentations or handouts relating to the topics covered during the course are available, published on the Virtual platform of the University of Bologna (virtuale.unibo.it).

The teaching material is in Italian and English.
