Impacts of Severe Storms on Beach Vegetation
In the winter of 1982/1983 the southern California coastline was subjected to a series of storms. High tides in conjunction with high swells reshaped beach topography in many areas. One...
Ebb-Tidal Deltas and Barrier Island Morphology
Offshore depositional features such as ebb-tidal deltas may have significant and perhaps controlling influence on barrier island morphology. These features serve three primary functions....
Geological Processes and Conservation Management Strategies for Barrier Islands of the Virginia Coast Reserve
A barrier island is a sandy deposit that is located immediately offshore and parallels a mainland coast. It is the principal environment of six interactive environments that make up the...
A Carrying Capacity Study of Hatteras Island
This article summarizes a study done of Hatteras Island, North Carolina, a largely undeveloped and natural barrier island. 'Carrying capacity' means the ability...
