National Assessment of Storm-Induced Coastal Change Hazards
The USGS National Assessment of Storm-Induced Coastal Change Hazards project assessed the storm events in the list below, in some cases as part of a real-time response. For each named storm, the response activities differ depending on the severity of the storm and may include:
Documenting pre-storm morphology using lidar topography, oblique aerial photography, and GPS ground surveys to determine the state of the beach before storm impact.
Assessing the probability of coastal-change impacts by comparing modeled elevations of storm-induced water levels to known elevations of coastal topography.
Measuring post-storm morphology using lidar topography, oblique aerial photography, and GPS ground surveys to determine the state of the beach after storm impact.
Quantifying storm-induced coastal change including dune elevation change, shoreline change, and beach and dune volume change by comparing pre-and post-storm morphology.
Evaluating and improving accuracy of pre-storm assessments (forecasts) of coastal change.
Updating assessments of coastal change probability by including post-storm beach morphology.
