Digital twin (DT)

Digital twin (DT): is a digital model of an intended or actual real-world physical product, system, or process that serves as the effectively indistinguishable digital counterpart of it for practical purposes, such as simulation, integration, testing, monitoring, and maintenance (Moi, Cibicik, and Rolvåg 2020; Haag and Anderl 2018; Boschert and Rosen 2016; Wikipedia 2024a).

Digital Twin solution for realistic sea level rise simulation

Digital twin technology is increasingly being used to simulate the effects of sea level rise, providing valuable tools for decision-makers in areas such as urban planning, coastal management, and disaster preparedness. These virtual models integrate real-time data from various sources, including geospatial imagery, AI, and environmental monitoring systems, to create detailed simulations of how rising sea levels could impact specific regions. 

An overview of digital twins in water systems

Short summary: Digital twin (DT) technology for water systems is currently blooming. How are DT applied in water systems and why did they become so popular? In this article, the framework of DT and crucial technologies to build them such as space-based satellites, modern communication technologies, artificial intelligence, etc. are revealed to present how DT functionality is implemented. Application scenarios of DT from global to regional are shown with typical examples for modeling the global water cycle, regional floods, and urban water supply systems. Though DT offers a valuable solution in the context of water systems, attention needs to be given to accuracy, interoperability and data security of DT. DT can be smart systems, helping in comprehensive analysis to support decision making.
