Investigating Regional Patterns of Shoreline Change
… exists. What are the physical processes driving shoreline change, and over what spatial and temporal scales are they manifest? If forces driving the littoral system change, how does the shoreline respond? Can we attribute observed patterns of shoreline change to a particular process?</p><p>Recent …

An Analysis of Shoreline Change at Little Lagoon, Alabama
In Alabama, the term "coastal shoreline" applies to the Gulf shoreline and the shorelines of estuaries, bays, and sounds connected to the Gulf of Mexico and subject to its tides. However, Alabama shoreline studies have yet to include Little Lagoon, which has been connected to the Gulf of Mexico for …

Managing for Self-Organization in a Changing World : Societal Responses to Shoreline Change
… communities to cope with and adapt to the changes brought about by the events in question. Determining how individuals and communities cope with such impacts - their resilience - can provide insight and understanding into avenues for adaptive management and strategies to cope with a range …

Decadal-scale evolution of a barrier island : Insights from storm overwash and shoreline change on Ocracoke Island, NC
… evolution in order to best prepare for future change. In this study, multiple methods were used to evaluate the recent decadal evolution of Ocracoke Island, NC. Shoreline change rates were calculated using a transect-based approach with imagery from 1949, 1974 and 2006. Other aerial imagery …

Change in Shoreline Position for Two Consecutive Years Using LIDAR Along the Outer Banks, North Carolina
<p>The signal of shoreline change for the Outer Banks, North Carolina is non-stationary. A baseline, west of the first line of dunes, is created for each 5 km section and shore-perpendicular profiles constructed every 20 meters in the alongshore direction. The profiles are obtained from two light …

Machine Learning and remote sensing applications to shoreline dynamics
… automated, and wide-scale determination of shoreline position, and its migration at the engineering scale (10-1 – 102 km), is imperative for future coastal risk adaptation and management. The recent increase in the acquisition and availability of Big Datasets, including multispectral remote …

Response and Recovery of Horn and Petit Bois Islands, Mississippi, USA to Tropical Cyclone Impacts: 2004 – 2016
… datasets from 2004 to 2016, spatial and temporal changes of the islands’ area, sediment volumes, and shorelines were measured to ascertain their geomorphic responses and recovery rates following the impacts of these devastating tropical cyclones. During the 2004–05 hurricane seasons, Horn Island …

Convexity, Concavity, and Human Agency in Large-scale Coastline Evolution
… by storm patterns, which are expected to change with the warming climate, and the associated changes in coastline shape are likely to increase rates of shoreline change in many places. Humans have historically responded to coastline change by manipulating various coastal processes, …

A Comparative Analysis of the Subsurface Stratigraphic Framework to the Geomorphic Evolution of the Caillou Bay Headland, South-Central Louisiana
… This research investigates historical changes in the surface geomorphology of the Caillou Bay headland in relation to the distribution of subsurface lithosomes. The stratigraphic framework was developed for the headland, and lithosomes were identified to establish the distribution of …

Coastal vulnerability assessment of Co. Dublin and Co. Wicklow to impacts of sea-level rise
… in understanding coastal exposure to water-level change was quantifying the important characteristics that make it susceptible to change over the next century. The bulk of the work comes from identification, compilation and quality control of indicators of coastal change, which in this area were …

Assessing the Effects of Sea-Level Rise on Piping Plover (Charadrius Melodus) Nesting Habitat, and the Ecology of a Key Mammalian Shorebird Predator, on Assateague Island
… Coast and is highly vulnerable to habitat change and predation. We have addressed these two threats by 1) developing and implementing a linked model system that predicts future change to piping plover habitat resulting from sea-level rise and beach management efforts by joining dynamic …

Tidal hydrodynamic response to sea level rise and coastal geomorphology in the Northern Gulf of Mexico
… submergence, increased flooding, and increased shoreline erosion. Low-lying coastal environments such as the Northern Gulf of Mexico (NGOM) are particularly vulnerable to the effects of SLR, which may have serious consequences for coastal communities as well as ecologically and economically …

Infragravity waves over topography : generation, dissipation, and reflection
… nonlinearity is important. Infragravity waves exchange energy with swell and wind waves (periods from 5 to 20 s) via conservative nonlinear interactions that approach resonance with decreasing water depth. Consistent with previous results, it is shown here that as waves shoal into water less than …
