Pumping In and Pumping Out: Case Histories of Fluidized Sand Bypassing for Channels and Beachface Dewatering for Beaches
New technologies can change management of sand in coastal areas. Fluidization, pumping in additional water beyond the quicksand point, makes a 50:50 sand-water slurry that will flow down...
Dune Maintenance
Beach nourishment and stabilization may be achieved through the replacement of sand eroded from the dune. A generalized description of the physical processes and the storm protection benefits...
Increased Attention to Ocean and Coastal Protection Legislation in the 101st Congress
For all the grumbling about the ineffectiveness of Congress, the 101st Congress produced a surprising number of critical pieces of coastal- and ocean-related legislation, and began the...
Management of Sandy Inlets: Coastal and Environmental Engineering Imperatives
Management of sandy tidal inlets is required for maintenance of navigable channels and control of beach erosion. Management elements essentially entail 'resharing'...
A Re-Evaluation of Earthquake Hazards Within the California Coastal Zone: Lessons from the Loma Prieta Earthquake
The 7.1 magnitude Loma Prieta earthquake occurred on October 17, 1989, had a duration of 15 seconds, and took 62 lives. Among the lessons learned from this earthquake with regard to offshore...
Geotechnical Failure of Revetments
A calculation method is developed to analyse the stability of a granular subsoil underneath a revetment under wave attack. This method leads to a minimum revetment weight per square meter...
Geological Assessment of Offshore Sand Deposits
The United States Atlantic and Gulf of Mexico continental shelf contains large numbers of surficial sand deposits. The search for sand resources for metropolitan construction and coastal...

This paper highlights past to present nearshore Scotian Shelf heavy mineral and aggregate exploration activities and findings. Promising sites for heavy minerals, gold and extensive sand...
The Application of a Geographical Information System to Resource Management?The UK Offshore Sand and Gravel Case
In the United Kingdom coastal and offshore environments, the extraction of sand and gravel from the seabed requires a high level of professional management, because of the varied and often...
Grunion Spawning Versus Beach Nourishment: Nursery or Burial Ground?
At Cabrillo Beach in San Pedro, California, a major sand renourishment project was scheduled to commence during the annual grunion spawning season, which occurs from February through August....
Environmental Impact on Sepetiba Beach
This paper describes the erosive and sedimentary processes which have been causing damage to the most important beach on Sepetiba Bay in Brazil. Remote sensing techniques and data obtained...
Nature-Assisted Dune Restoration
The concept of finding and placing compatible sand along the coastal shoreline for dune restoration is presented. Laboratory experimental result supporting this concept is reported. Field...
Roadside Associated Disturbance on Coastal Dunes
Park Road 100 extends through the developed southernmost 8 km of South Padre Island and continues northward for 11.5 km through the Secondary Dunes and Vegetated Flats (SDVF) zone of the...
Management of Great Lakes' Sandy Barriers: The Conceptual Challenges
Sandy barriers are dynamic, significant, and sensitive resource systems, comprising portions of the 18,000 km of Great Lakes shore. Use, development, and management of these features,...
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...
Ecological and Geomorphic Impact of the Destruction of a Coastal Sand Dune System in a Sand Spit
Two main effects of the destruction of the coastal dunes at the sand spit of Estero de Punta Banda, (B.C., Mexico) were studied comparing unaltered and altered adjacent zones, The amount...
Mercury-Contaminated Sludge Treatment by Dredging in Minamata Bay
To eradicate Minamata disease, caused by sewage containing methyl mercury accumulating in fish and shell-fish through the food cycle, a large-scale sediment disposal project was conducted...
Submarine Sand Ridges: Unique Marine Environment and Natural Resources
Submarine sand ridges are large scale depositional sandy bodies on the inner shallow water continental shelves, which are mostly distributed in the macro tide area where the mobile sandy...
Sediment Yield Location Maps
The West National Technical Center of the Soil Conservation Service is compiling a series of colored sediment yield location maps for the eleven western United States, as well as Alaska...
Review Notes on Cohesive Sediment Erosion
