Abstract

Beach barrier systems along the coast of Phippsburg, Maine, provide understanding to processes affecting the seasonal and long-term changes of the coast. From long-term environmental issues, including deglaciation and sea-level rise, to anthropogenic affects, these beach barriers are in constant flux. Continuing to monitor these dynamic barrier systems is necessary, it provides further knowledge on the seasonal processes and better information for continuing studies.

Barrier beaches are heavily influenced by the migrating paths of the tidal inlets, Morse River and Sprague River. Popham, Seawall and Small Point pocket beaches, Little and Icebox Beach, are the beaches representative of the changing coastal landforms. These beaches have seen dramatic changes and erosion over the past decade, concurring with shifts in courses of the tidal channels which linked the coastal back-marshes to the ocean.

Through topographical surveying of the beach barriers and GPS mapping of tidal channels, this study will examine the processes affecting beach morphology.
