Potential Hydrodynamic Loads on Coastal Bridges in the Greater New York Area due to Extreme Storm Surge and Wave

This project makes a computer modeling study on vulnerability of coastal bridges in New York City (NYC) metropolitan region to storm surges and waves. Prediction is made for potential surges and waves in the region and consequent hydrodynamic load and scour at bridge piers in conditions of climate change/sea level rise (SLR) and change in hurricane patterns. In particular, two tasks are (1) Computer modeling of storm surges and waves in the greater NYC area during hurricane Sandy, and the modeled results compare reasonably with field observation. (2) Prediction of storm surges and waves in the region in conditions of SLR and change of hurricane patterns, and, on this basis, a preliminary estimate of hydrodynamic load and scour at selected bridges along the coastlines. The study indicates that both rise in sea level and change in hurricane patterns could result in pronounced increase in hydrodynamic load and scour at bridge piers, and such increase should be taken into consideration in development of resilient coastlines.
