In correspondence to consequences of change in climate and hurricane patterns, this research investigates impact of ocean surges and waves on coastal bridges and the resulting vulnerability of them to extreme surges and waves during storms and tsunamis. Computer modeling study is made on wave impingement at coastal bridges to understand relevant physical phenomena, and analysis is presented on mitigation measures. Modeling systems are developed for high fidelity simulation of surge and waves at bridges. Hindcast modeling has been made for storm surges and waves in the metro NYC region during the Hurricane Sandy, and, on this basis, potential extreme surge and wave events in this region are predicted in conditions of sea level rise and different hurricane patterns in the future, together with analysis on vulnerability of coastal bridges to scour and hydrodynamic load. The results of this project shed light in understanding of involved physical processes and phenomena, and they present new modeling capacity for their prediction. It is anticipated that the results of this project will be beneficial to development of future coastal bridges and resilient coastlines.
