Abstract: As catastrophic events become increasingly frequent, infrastructure systems face rising challenges from the dynamic environment. Enhancing the resilience of the current infrastructure system in advance has emerged as an essential strategy for catastrophe preparedness. This study explores the novel concept of resilience bonds in the context of financing flood-resilient infrastructures, using the Towyn Flood as a case study. It examines the mechanism of resilience bonds in developing infrastructure capable of withstanding floods, analysing the resilience bond value and the factors influencing its valuation. Simulation results indicate that resilience bonds can significantly extend investment resources, enhancing flood resilience and reducing unforeseen flooding risks. A sensitivity analysis provides detailed insights into how various factors impact the resilience bond's pricing model. These findings offer critical guidance for decision-makers considering the implementation of resilience bonds in flood-prone areas, highlighting their potential to improve infrastructure resilience against catastrophic events.
