Summary

Barrier islands provide important ecosystem services, including storm protection and erosion control to the mainland, habitat for fish and wildlife, and tourism (Barbier and others, 2011; Feagin and others, 2010). These islands tend to be dynamic due to their location along the estuarine-marine interface. Besides gradual changes caused by constant forces, such as currents and tides, barrier islands face numerous threats including hurricanes, accelerated sea-level rise, oil spills, and anthropogenic impacts (Pilkey and Cooper, 2014). These threats are likely to influence the future of barrier islands in the latter part of the 21st century, especially as climate-related threats to coastal areas are expected to increase in the future [...]

Purpose

Barrier islands provide important ecosystem services, including storm protection and erosion control to the mainland, habitat for fish and wildlife, and tourism (Barbier and others, 2011; Feagin and others, 2010). These islands tend to be dynamic due to their location along the estuarine-marine interface. Besides gradual changes caused by constant forces, such as currents and tides, barrier islands face numerous threats including hurricanes, accelerated sea-level rise, oil spills, and anthropogenic impacts (Pilkey and Cooper, 2014). These threats are likely to influence the future of barrier islands in the latter part of the 21st century, especially as climate-related threats to coastal areas are expected to increase in the future (Knutson and others, 2010; Hansen and others, 2016). As a result, natural resource managers are concerned with monitoring changes to these islands and modeling future states of these environments. This model framework could be coupled with hydrodynamic geomorphology models that can incorporate coastal morphodynamics and dune evolution for forecasting alternative states of barrier islands with and without various management actions or for producing contemporary or historical detailed barrier island habitat maps using remotely sensed imagery and light detection and ranging (lidar) data. These data were created for one component of a larger collaborative effort between the U.S. Army Corps of Engineers, the State of Alabama, and the U.S. Geological Survey, funded by the National Fish and Wildlife Foundation Gulf Environmental Benefit Fund (project ID: 45719) to investigate viable, sustainable restoration options that protect and restore the natural resources of Dauphin Island, Alabama.
