Assessing and Mitigating Transportation Infrastructure Vulnerability to Coastal Storm Events With the Convergence of Advanced Spatial Analysis, Infrastructure Modeling, and Storm Surge Simulations

69A3551847102In this project, the research team studied the convergence of remote sensing, digital twin, web technologies, and flood simulation for creating an advanced flood preparedness system. The project used Manville, a frequently flooded township in New Jersey, as an exemplar case. The team created a calibrated hydrodynamic model for the entire township and beyond. The team also mapped out the entire township with a high-resolution 3D mapping system, and created a digital twin for the entire township. We extracted key elevation information for buildings and critical infrastructure systems, and used them in joint with the hydrodynamic models to assess flood impacts. The flood impacts focused on buildings and accessibility to emergency services. We created two modules of assessment tools for these purpose so that they are generalizable to other places. At the end, we created a flood information dashboard which serves a center place to visualize hydrodynamic model results and flood impacts to communities and to support decision making in flood mitigation choices. The project is the first application of integrating mobile lidar derived city level data with hydrodynamic models for flood impact visualization and analysis
