A millennium-long management perspective for promoting the geological-social resiliency of barrier islands: a preliminary proposal for Fire Island, NY

摘要: Barrier islands, such as Fire Island, NY, are complex geological-social systems, driven by mesoscale (centuries/ millennia) processes. The natural resiliency of these thin, linear landforms depends mainly on their capacity to migrate land- ward (rollover) in response the slow, persistent rise sea level. This happens overwash processes during storm surges, whereby beach and dune sand ocean side is eroded transferred island's interior back-barrier shore. Also breaches inlet formation enable de- velopment flood-tidal deltas, which likewise supply large volumes backshore barriers. If curtailed shortsighted engineering solutions, barrier islands will lose morphologic either disin- tegrate or drown place. ideas this paper argue for a millennial management perspective based not interfering with process rollover over geologically significant spans time. To be effective, people need think about adapting continual change system level, rather than relying conventional, short-term so- lutions local erosion problem, strategy that compromise integrity Island level continues foreseeable future.
