Supporting Resilience Management of Water Distribution Networks through Network Analysis and Hydraulic Simulation

Resilience is usually associated to the capability of a networked infrastructure to guarantee an acceptable service even if some failure occurs. The paper presents a framework based on network analysis and software hydraulic simulation to supporting the resilience management in Water Distribution Networks increasing the sustainability of these Cyber Physical Systems while saving water and energy. The benefits of the proposed framework are evaluated on three real-world Water Distribution Networks. While graph-based measures computed on the graph associated to the physical network allows for computing network-wide measures and identifying components which are critical for the connectivity of the physical infrastructure (vulnerabilities) software hydraulic simulation is used to evaluate the impact of a failure on the supply service.
