An Integrated Dynamic Modeling Approach for Flooding of Coastal Transportation Infrastructure Assessment of Impacts on Emergency Operations

Low-lying coastal areas of Hampton Roads, Virginia are vulnerable to recurrent flooding. Flooding impacts are exacerbated by climate change and sea level rise as the region is experiencing the nation’s second highest rate of relative sea level rise. With climate change, the intensity and the frequency of storms are expected to increase and make the region more susceptible to coastal flooding. As such, addressing frequent flooding problems is the top priority in the City of Norfolk. Of particular interest is the flooding impact on access to emergency care facilities in the City. Sentara Norfolk General Hospital houses the only Level 1 trauma center in the region and is located near the Ghent neighborhood. During high tides, storm surge, and heavy rain situations, the transportation network near this area floods, leading to challenges in accessing the trauma center. These challenges can have life threatening implications. For major trauma victims, the “golden hour” is critical; during this hour immediately after the injury, medical treatment has the highest likelihood of preventing death. Transportation delays have clear detriments in this setting and the delays are only anticipated to worsen over the years without intervention. Therefore, it is critical to predict the flooding impact on access to the facility, and plan emergency operation such that alternatives exist for areas with disrupted access to the trauma center. To achieve this, reliable estimates of flooding depth, duration, and spatial distribution over the transportation infrastructure are needed. These estimates can then be used to optimally position mobile medical assets.
