Conducted through cyber and/or physical channels, water supply terrorism seeks to compromise the availability and quality of drinking water. This threat has direct consequences on the population and on the resilience of the city.

Today, with the digital revolution, the resilience of a water distribution network (WDN) is linked to the security of information systems (IS). Failure detection and any appropriate countermeasures depend not only on the design of the WDN, but also on the integrity of the IS, composed of the sensor network, the monitoring system, and their data.

The aim of the CoRREau project is to address these issues by proposing digital solutions for the hydraulic network.

The CoRREau project's solutions integrate a "digital twin" connected to real-time observations and built from a hydraulic model of WDN, on the one hand, and a "digital shadow" trained and then activated from computer network traces, on the other. The mutual contributions of the digital twin to the detection of anomalies, and that of the digital shadow to the overall resilience of both infrastructures will be analysed, in order to pave the way for a complete digital twin integrating the two systems. Multi-objective optimisation for optimal design and anomaly detection will be addressed by genetic algorithms. The case studies will be based on scenarios of interest proposed by the Strasbourg water utility in France.
