Creating and operating a simulation-based digital twin service for the ARSINOE project

Within the field of water engineering, digital twins represent an exciting new technology that offers opportunities within both simulation and visualisation to create applications that allow non-expert users (in water engineering) to visualise and hypothesise potential scenarios based on real-world situations allowing for both short-term tactical and longer-term strategic decision making and policy setting to be considered. This paper presents the design, implementation and operation of a flooding digital twin for the ARSINOE project [1] based on flood, traffic and cascading failure modelling for the Torbay region of Devon, for the Torbay municipality. Simulation results are presented through a Mapbox-based website, and considerations are given to future development steps. This paper was presented at the 21st Computing and Control in the Water Industry Conference (CCWI 2025) at the University of Sheffield (1st - 3rd September 2025).
