The final meeting of the ZwillE project took place at the Hannover Municipal Drainage Authority (SEH). The project impressively demonstrated how a digital twin developed with the help of SIMBA# and ifakFAST enables cities to proactively manage extreme weather events and thus strengthen urban resilience.
Essentially, a virtual image of Hanover's drainage infrastructure was created, linking high-resolution weather forecasts with real-time measurement data. The following three core elements were particularly important in the project: mapping the current status quo, short-term planning of countermeasures in the event of heavy rain or flooding, and long-term planning of infrastructure adjustments.
Another focus was on suitable user interfaces that enable quick and clear access to all relevant information. In addition, AI-supported decision assistance provides support by transparently integrating experience and expert knowledge and delivering comprehensible recommendations for action.
We would like to express our sincere thanks to all our cooperation partners and the Federal Ministry of Research, Technology, and Space (BMFTR) for their support, which made the success of the ZwillE project possible. We look forward to transferring the technology developed to other cities, thereby making an important contribution to sustainable water management and urban resilience.
