The huge socio-economic impact of extreme weather on coastal communities has been clearly highlighted by recent hurricanes. For example, it is estimated that in 2017 there were over a dozen separate climate events causing losses exceeding one billion dollars. Losses caused by only three of these events (hurricane Maria, Harvey and Irma) are estimated to have exceeded $300 billion. In order to increase the resilience of communities to such events, a new generation of multi-fidelity surrogate-based simulation frameworks are required. In particular, coupled simulation environments are fundamental to fully capture the true extent of damage and losses caused by the combined action of severe winds, flying debris and storm surge (including pluvial flooding). This project brings together fine-grain hurricane vulnerability models with state-of-the-art flood models within a coupled multi-fidelity surrogate-based simulation framework that has the potential to shed new light on the evolution of damage and loss during events such as hurricane Harvey.
