Lidar topography sequence showing the Chandeleur Islands, berm construction (Feb 2011), and subsequent berm and island evolution.

Medium-term coastal evolution involves the interaction of submerged and subaerial geomorphology, oceanography, sediment supply and other geologic constraints, and biological interactions associated with marshes and dune grasses which may capture or release sediments. The resulting sediment budgets determine the balance of topographic and bathymetric elevations and dictate how barrier island trajectories will proceed in the future.
