CD33A:
Barrier Dynamics in a Changing Climate I


Session ID#: 37748

Session Description:
Barrier islands, spits and plains are dynamic environments shaped by interactions between marine and aeolian processes, plants and animals, underlying geology, sediment availability, and human development. They typically consist of beach-dune systems, washover plains, salt marshes and adjacent inlets. Sea-level rise and climate change have put many barriers around the world at risk, especially as they become more developed. We need a quantitative understanding of how biotic and abiotic processes interact to build, move, and influence the long-term (in)stability of these landforms. We invite multidisciplinary contributions on the human influences and bio-morphodynamic feedbacks between plants, sediment, and flow of air and water on barriers, and contributions on specific aspects of barrier dynamics. The scope may vary from the local spatial and event time scale, to the scale of chains of barrier islands and millennia.
