The aim of the ZwillE project is to develop methods and tools for the creation of a digital twin of the urban drainage infrastructure as a basis for proactive management of extreme weather events in urban areas. By linking simulatable models with high-resolution forecast data, the concept of the digital twin is realised in the form of a virtual image of the real drainage system. This virtual image is a precondition for the effective management of extreme weather events.
The concrete scientific and technical sub-goals of ifak are to improve the methods and tools for creating a digital twin of the urban drainage infrastructure and to make them suitable for practical use. Within the scope of the project, an integrated simulation model of the drainage infrastructure of Hannover will be created. The simulation model is to be used by linking it with real-time measurement data for the use cases (1) representation of the current state, (2) short-term planning of measures to cope with extreme weather events and (3) long-term planning of infrastructure adaptations.
A particular challenge is to create suitable user interfaces for the different use cases and to achieve the integration of the decision support function based on methods of explainable artificial intelligence with the inclusion of empirical knowledge.
