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

<p dir="ltr">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.</p><p dir="ltr">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).</p>
