Detailed Description
Examples of sediment dynamics offshore of barrier islands include the development and erosion of shoals, tidal deltas, and sand ridges. The perspective block diagrams above show elevations for a portion of the seafloor adjacent to Dauphin Island, Alabama (top left), measurement of accretion and erosion of these features (top right) reveal their dynamic nature over the past half-century. Data source and analysis from DeWitt and others (2018) and Flocks and others (2017).

Coastal Resource Evaluation for Management Application (CREMA)
Coastal environments are dynamic systems that provide high ecological, economical, recreational, and cultural value. Managing coastal systems requires a comprehensive understanding of the complex interactions between geological and ecological processes, as well as the ability to predict both the near-term and long-term impacts of storms and sea-level rise.
