Barrier islands and their associated backbarrier ecosystems front much of the U.S. Atlantic and Gulf coasts, yet threshold conditions associated with their relative stability (i.e., state changes between progradation, erosion, and landward migration) in the face of sea-level rise remain poorly understood. The barrier islands along Virginia's Eastern Shore are among the largest undeveloped barrier systems in the U.S., providing an ideal natural laboratory to explore the sensitivity of barrier islands to environmental change. Details about the developmental history of Parramore Island, one of the longest (12 km) and widest (1.0–1.9 km) of these islands, provide insight into the timescales …

Predicting coastal infrastructure reliability during hurricane events is important for risk-based design and disaster planning, including delineating viable emergency response routes. Previous research has focused on either infrastructure vulnerability to sea-level rise and coastal flooding, or the impact of changing sea level and landforms on surge dynamics. This paper represents a multidisciplinary effort to provide an integrative model of the combined impacts of sea-level rise, landscape changes, and coastal flooding on the vulnerability of highway bridges - the only access points between barrier islands and mainland communities - during extreme storms. Coastal flooding is forward modeled for static projections of …
