WADITI - developing a roadmap for a water quality digital twin. A scoping study under UK-SCAPE

In this study, we develop a roadmap for a surface water quality digital twin, to provide now-casting and short-term forecasting of a range of environmental pollutants and ecosystem states in both rivers and lakes. Although shorter-term dynamics are our focus, we note that digital twins can be applied to longer-term system behaviour as well. Our aim was to integrate numerous aspects of water quality and UKCEH expertise in monitoring networks, data science, hydrological and water quality, and river and lake ecosystem modelling. Thus, we reviewed current data streams, available models, and data science approaches. We built upon the existing body of work that considers how best to conceptualise environmental digital twins.
