A Dynamic Hurricane Risk Modeling Framework to Improve Bridge Safety under Changing Climate

Coastal regions have been experiencing more frequent and more intensive tropical cyclones (TC) due to climate change in recent years. In 2020, the tropical storms in the Atlantic Ocean made a number record in a season, with 30 named storms in total, 13 of which progressed into hurricanes. Global warming will continue and climate change will follow (USGCRP, 2018), leading to more severe winds and storms and threating the safety of bridges in coastal regions. In order for local governments to take pro-active adaptations and measures, it is essential to understand the local impact of global climate change. To address this, this project will develop a new, efficient hurricane wind model and then develop a new, dynamic hurricane risk modeling framework that can reflect climate change. This will inform decision-makers when they develop near-term measures and long-term plans for mitigation and adaptation to climate change. To achieve this research goal, the following two research tasks have been planned. First, by balancing the advantages and disadvantages of existing parametric TC models for engineering applications, this project will develop a high-fidelity, computationally efficient three-dimensional nonlinear TC model that can consider the varying land cover and terrains without too much simplification of the kinetic equations. Second, the developed hurricane wind model will be used to generate a great number of synthetic hurricanes to develop a hurricane risk model that can reflect the changing climate. The obtained results can be used to improve the American Association of State Highway and Transportation Officials (AASHTO) Bridge Design Specifications periodically to accommodate the future climate change, enhancing the resilience of bridges.
