Water safety is a huge challenge in delta areas. Flood prevention and management require that water be seen as an important spatial and societal structuring element. Based on thorough analysis, we both provide and contribute to the design of future-proof and (data-) intelligent water infrastructure. Our Digital Twin approach is a useful tool (Digital Water) in this process. The approach links the infrastructure’s physical and digital identities in an inextricable manner. The objective is to have a traceable, future-proof and reliable water infrastructure. This approach leads to improved efficiency, cost reductions and a reduced failure probability in every phase of the infrastructure’s lifecycle. We have collected our instruments and competences in the SPiFRAME and REDO Toolboxes. We can work with these, together with the client, in making projections and supporting the adaptable design of future-proof water infrastructure.
