St. Petersburg Coastal and Marine Science Center
USGS forecasts of coastal change during hurricanes provide critical information to identify areas vulnerable to extreme, and potentially catastrophic, erosion during landfall. The Storm Impacts and Vulnerability of Coastal Beaches project will use post-Sandy lidar elevation data to update assessments of storm-induced coastal erosion hazards for Northeast beaches. Extensive data sets on beach morphology and storm hydrodynamics will be used to evaluate and improve the accuracy of pre-landfall forecasts of erosion. Social, economic, and infrastructure elements will be incorporated into the forecasts to identify community exposure and sensitivity to coastal-change hazards.

Post-Sandy Coastal Elevation and Elevation Change Data
Provide post-Sandy coastal elevation data from post-storm surveys including extracted features such as shoreline position and dune elevations. Calculate magnitudes of dune, shoreline and beach volume change from NY to NC.
Update Assessments of Storm-Induced Erosion Hazards on Sandy-Impacted Coastlines
Calculate probabilities of coastal change during category 1-4 hurricanes using post-Sandy dune elevations and beach slopes. Develop wave climate scenarios for nor'easters and other regional storm conditions and assess associated coastal change hazards.
Assess Coastal Impacts of Sandy and Evaluate Accuracy of Pre-Storm Forecasts
Describe the coastal change caused by Hurricane Sandy, evaluate accuracy of pre-landfall forecasts of coastal erosion, investigate reasons for observed errors, and propose new research directions aimed towards improving model performance.
Assess Community Vulnerability to Coastal Change Hazards for Hurricanes and Other Storm Scenarios
Describe variations in community exposure and sensitivity along the U.S. eastern seaboard to post-Sandy coastal-change hazards associated with category 1-4 hurricanes, wave-climate scenarios, and sea-level-rise scenarios
Automate Coastal Change Probability Forecasts
Define wave/weather scenarios, real-time inputs, and required outputs. Develop user-friendly tools and results for a wide range of users.
Improve Forecasts of Beach Change During Storms
Study the evolution of the beach during storms and incorporate into coastal change models. Improve models of wave runup during extreme events. Examine the role of vegetation in dune erosion and recovery. Integrate storm-scale coastal change hazards with longer term changes, including sea level rise.
