Abstract:This report focuses on the transportation resiliency of the Long Wharf area in the City of New Haven, CT,
with the aim of identifying resiliency strategies for these transportation assets. The report begins with
reviewing the important transportation assets in Long Wharf area, which includes highways, bridges and
railways. Subsequently, a statistical analysis is carried out to regress the extreme water levels to atmospheric
forcing in the region. In order to simulate the potential total water level, a simulation scheme that combines a
high-resolution atmosphere model, a land-surface model and a parametric wind-wave model is devised,
considering both the actual Superstorm Sandy and simulated future scenarios. The derived total water levels
from actual and future Sandy simulation scenarios are used to generate GIS-based flood inundation maps for
the study area, followed by the evaluation of resiliency of the transportation assets due to flood hazards during
hurricanes. Finally, based on a comprehensive review of the resiliency options utilized across US coastal
regions, potential resiliency options are made for the study area.
