Beach and Barrier Dynamics Science Topic


Beach and barrier dynamics for the Atlantic Ocean and Great Lakes can vary extensively based on the sedimentary environments of these systems. Likewise, the settings can be complex and include components of mainland beachs, barrier islands and dunes, tidal flats and barrier platforms, salt marshes and lagoons, ponds, alluvial fans and inlet deltas, to name a few. The combination of wave, tidal, and storm impacts to coastal morphology also can differ by geographic location. However, barrier islands and spits may be the most vulnerable to changing sedimentary conditions due to human intervention, periodic extreme storms, and accelerating sea-level rise. The USGS is working to enhance mapping of these dynamic settings and provide long-term [...]
