Coastline Management: A Challenge for Developing Countries
Coastal erosion has been a worldwide problem of primary concern to coastal management and development. To arrest the coastal erosion processes along the coastline of developing countries...

Effects of Sea Level Rise on the California Coast
Although California is thought to be an emerging coastline which would be little affected by a change in sea level, a 5 foot rise over the next 100 years could have a significant impact...

Success of Dune Restoration After Removal of UXO
The discovery of unexploded ordnance (UXO) at South Beach, a popular recreational beach on Martha's Vineyard island in Massachusetts, necessitated that the area be declared...

The Exxon Valdez Oil Spill: Update on Persistence and State of Alaska Activities
The Exxon Valdez incident of 24 March 1989 caused the oiling of over 1,100 miles of Alaskan coastline and over 11,000 square miles of coastal waters. The State responded immediately to...

Land-Use Issues Raised by Offshore Oil and Gas Development
While prudent development of offshore energy resources may provide benefit to the nation overall, it invokes several issues for local and regional planning. In particular, petroleum development...

Effective Mitigation of Air Emissions from OCS Sources
Unmitigated, platforms and associated facilities in the OCS typically emit large quantities of air pollution from power generation, drilling, transportation and other activities related...

How to Pay for Coastal Protection: Governmental Approaches
Beach erosion is a major problem in the United States, particularly in California. At the same time, coastal resource protection is becoming increasingly expensive as state and federal...

Critical Examination of Longshore Transport Rate Magnitude
Inconsistencies in the field data and predictions of longshore sediment transport (LST) rates associated with the CERC and Bagnold formulae are discussed. Practical errors in direct application...

Field Measurements of the Vertical Structure of Suspended Sediment
The use of acoustic backscatter measurements to determine suspended sediment concentration gives a new view of the instantaneous sediment distribution as a function of height above the...

The Sedimentary Organisation and Behaviour of Drift-Aligned Gravel Barriers
Drift-aligned barriers formed of coarse clastic materials and described in terms of their organisational evolution at two levels, a) sorting and selection of clasts; b) development of...

Gravel Spit Stabilized by Unusual(?) High-Energy Wave Climate in Bay Side, Tierra Del Fuego
A 17 km-long sand and gravel spit grew from the Atlantic coast of Tierra del Fuego in the late Holocene, semi-enclosing a large and deep embayment. Strong westerly winds generate high-energy...

Accurate Shoreline Mapping: Past, Present, and Future
Mapping historical shoreline changes and predicting future shoreline positions requires both accurate and precise analyses of time-dependent fluctuations in water levels and sediment volumes...

Mapping Barrier Island Changes in Louisiana: Techniques, Accuracy, and Results
Changes in shoreline position along Louisiana's rapidly changing barrier coastline were compiled using cartographic data sources and aerial photography from 1855 to 1989. An interactive...

Accuracy Standards and Development of a National Shoreline Change Data Base
Data associated with mapping shoreline position provides baseline information used by scientists, managers, and planners for quantitative assessment of historical trends and prediction...

Keys to High-Accuracy Mapping of Shoreline Changes
For many years it has been difficult to overlay maps and aerial photographs with different scales and publication dates using conventional techniques. Large processing errors also made...

Geologic Framework and Depositional History of the Southeastern Texas Coast
Effective management of coastal resources and accurate prediction of future land losses are impeded by the lack of geologic framework investigations that link coastal processes with depositional...

Geologic Controls on the Formation and Evolution of Quaternary Coastal Deposits of the Northern Gulf of Mexico
A study of the barrier islands and wetlands in the deltaic plain of Louisiana is presented. Its purpose was to document rapid changes and to learn more about the processes responsible...

Morphodynamics of the Isles Dernieres Barrier Shoreline, Louisiana: 1984?1989
An aerial videotape mapping system was used to monitor spatial and temporal variability of the coastal morphology along the Isles Dernieres barrier shoreline. Between 1984 and 1989, nine...

Late Quaternary (Pre-Holocene) Coastal Systems of New Jersey
The coastline and the area adjacent to the present shoreline of New Jersey has not been explored as intensely as the same region of neighboring states for pre-Holocene high sea level stillstands....

Migrating East Australian Barriers and Reefs Under Greenhouse Scenario
Geological evidence which bears directly on the question of human-induced sea-level change and migrating shorelines is difficult to find. If we could find an ancient analog of the rapid...
