“…As Vezér et al (2018) indicate, simple economic decision-making models are better affordable, more transparent, and more amenable to reproducibility and scrutiny. Moreover, simpler models can assess a wider range of options and scenarios, as van Berchum et al (2019van Berchum et al ( , 2020 and Ceres et al (2019Ceres et al ( , 2022 promote. They also help in policymaking preceding more detailed analyses supporting the final investments.…”

Storm surge barriers are large movable hydraulic structures which close during a storm surge to prevent coastal floods. In the regions they protect, a failure to close the barrier is often the most likely cause for a catastrophic flood. Nevertheless, flood risk assessments usually only focus on raising flood defences behind the barrier. Despite its importance, there is no general method to assess the costs and benefits of improving the closure reliability. This paper presents a model that optimises investments considering both closure reliability improvements and raising flood defences behind the barrier, using the region protected by the Maeslant barrier as a case. We substantiate that constructing the Maeslant barrier was an optimal economic decision. Moreover, we demonstrate large investments such as a redundant barrier already being economically sound with a few decimetres of sea level rise. Based on our experience with this case study, we expect the model is useful in finding strategies to adapt to rising sea levels and other developments that cause coastal flood risk to rise worldwide.

“…More informed policies generally result in improved policy outcomes (e.g., Giuliani et al, 2019;Woodward et al, 2014). Policy search methods have been used in flood (Ceres et al, 2022;Kwakkel et al, 2015Kwakkel et al, , 2016Woodward et al, 2014) and urban water supply (Mortazavi-Naeini et al, 2015;Paton et al, 2014;Zeff et al, 2016) infrastructure planning.…”

Climate change uncertainty challenges water supply planning (Gleick, 1989(Gleick, , 2000. Infrastructure systems, which are designed to last for many decades, must perform well under highly uncertain conditions (Cosgrove & Loucks, 2015;IPCC, 2022). Traditional water supply planning approaches usually oversize water infrastructure using a safety factor to account for uncertainty and reduce the chance of system failure (Stakhiv, 2011). However, overbuilding adds costs and environmental impacts, which are especially detrimental in more resource-scarce regions. One strategy to plan under uncertainty is flexible planning. Flexible, or adaptive, planning approaches can help mitigate infrastructure over-or underbuilding by changing the design or operations of infrastructure to respond to evolving conditions over time (Bertoni et al., 2021;Culley et al., 2016;Hui et al., 2018). For example, flexible plans may respond to hydrologic shifts, like a climate trending drier (Kumar et al., 2013), or changing societal values, such as a focus toward sustainability and ecological benefits (Kermisch & Taebi, 2017). Flexible plans also have downsides. They require identifying signs of system vulnerability (Dewar et al., 1994;Haasnoot et al., 2013) to trigger adaptations (Walker et al., 2001), which assumes that we can identify a reliable signpost for when to adapt. This may not be the case in many systems (Raso et al., 2019). Flexible plans also are expensive and may require additional costs for monitoring systems or repetitive structural elements to allow for future adaptations (

Flooding is a global threat, necessitating a comprehensive management approach. Due to the complexity of managing flood hazards and risks, researchers have advocated for holistic, comprehensive, and integrated approaches. This study, employing a systems thinking perspective, assessed global flood risk management research trends, gaps, and opportunities using 132 published documents in BibTeX format. A systematic review of downloaded documents from the Scopus and Web of Science databases revealed slow progress of approximately 11.61% annual growth in applying systems thinking and its concomitant approaches to understanding global flood risk management over the past two decades compared to other fields like water resource management and business management systems. A significant gap exists in the application of systems thinking methodologies to flood risk management research between developed and developing countries, particularly in Africa, highlighting the urgency of reoriented research and policy efforts. The application gaps of the study methodology are linked to challenges outlined in existing literature, such as issues related to technical expertise and resource constraints. This study advocates a shift from linear to holistic approaches in flood risk management, aligned with the Sendai Framework for Disaster Risk Reduction 2015–2023 and the Sustainable Development Goals. Collaboration among researchers, institutions, and countries is essential to address this global challenge effectively.
