Hydrodynamic/GIS Simulation of Storm Surge Flooding in the NY/NJ Harbor System
In order to evaluate the effectiveness of storm surge barriers for reducing storm impacts at locations within the NY-NJ Harbor System, a three-dimensional hydrodynamic model was used to simulate several conditions, and resultant sea level data was used in GIS to assess inundation extent. The validated hydrodynamic model was used to simulate several storm surge events under three projected climate change-related sea level rises with and without operation of the four storm surge barriers. Storm surge barriers would reduce the maximum water elevations as much as 1.5 m at locations protected by the storm surge barriers. A GIS model was developed and a series of iterative processing steps were performed to delineate the inundated area based on the storm surge model results for each scenario. The results indicate that implementation of storm surge barriers would likely result in significant benefits with regard to land area flooded (roughly 25 percent less), population affected (roughly 20 percent less), property value impacts (roughly 35 percent less), and number of hazardous material/waste sites impacted (roughly 50 percent less).
