St. George Harbor?A Berm Breakwater Solution in Alaska's Bering Sea
The berm breakwater concept is based on the premise that locally available materials should be used in breakwater construction to the largest degree possible. By looking at failure dynamics...
U.S. Port Commerce in Radioactive Materials (
In the ten-year period assessed, total radioactive materials handled at U. S. ports expanded by over 19,000 tons, which amounts to almost a 173 percent growth rate. This abstract refers...
Collective Response to Erosion Along the Nigerian Coastline
Natural factors for the rapid coastal erosion include an intense wave climate, a low coastal plain topography, vulnerable sediment or soil characteristics and, the global eustatic rise...
A Case Study of the CEQ Worst Case Regulation
This paper focuses on a decision by the U. S. Army Corps of Engineers (Corps) not to include a worst case oil spill analysis in the Environmental Impact Statement (EIS) for a proposed...
Properties of Tin-Mined Land in Mangrove Forest, Thailand
Although mangrove forests occupy a very small area of Thailand, they contribute not only an ecosystem but also large tin ore deposits. Two provinces in the South, Ranong and Phangnga,...
Integrated Disposal Studies in San Francisco Bay
The United States Army Corps of Engineers is studying the accumulation of dredged material at the Alcatraz Disposal Site in San Francisco Bay. Alcatraz was chosen for aquatic disposal...
Decisionmaking for Dredggedg Material Management
Management of dredged material produced in coastal environments is greatly complicated by the presence of chemical contaminants in the material. The kinds and quantities of contaminants...
Coastal Dunes for Protection and Sand Resources
Massive mining of dune sand on the north coast of Puerto Rico has impaired the natural ability of the dunes to protect the coast from high waves and long-term erosion. This paper presents...
Beach Stabilization Design
There is a need for aesthetically pleasing and environmentally satisfactory solutions for protecting, renovating and restoring eroding semi-protected coastal beaches such as those found...
Concrete Armor Mats: Large-Scale Wave Tank Tests Wave Stability Tests
Concrete mats provide an alternative to the more conventional shoreline stabilization techniques. Material requirements are low, placement techniques are straightforward and they tend...
Parameters Controlling the Success of Dune Revegetation at King Salmon, California
An eroded 9. 3 ha (23 acre) sand spit was restored through jetty construction and fill (using dredge spoils) by the Corps of Engineers at King Salmon on Humboldt Bay, California. An experimental...
Effects of Toxic Chemical Perceptions on Fishing Behavior
This study investigates: 1) whether angler's who perceive toxic chemicals in the water fish any differently than those who do not, and 2) do these behavioral differences have...
REMOTS?: Reconnaissance of Benthic Environments
REMOTS(REGISTERED TRADEMARK) technology, a combination of sediment-profile photography and computer image analysis, was developed to address shortcomings in traditional benthic sampling...
Beach Preservation by Means of Offshore Submerged Mound of Dredged Materials
The beach - sediment - dispersion- offshore or alongshore under the effect of waves and wave induced currents, and inland by wind action may cause a net deficit in sediment budget which...
Evaluation of Sand-Filled Containers for Beach Erosion Control: an Update of the Technology
The use of large, sand-filled geotextile containers for coastal erosion protection has increased along Florida's ocean shorelines over the past five years. Technological advances...
A Comparison of California's Coastal Programs
California is the only state that has two distinct coastal management programs for two different geographic segments of the state's coastal zone, with each program administered...
Territorial Sea Management by the State of Oregon
The institutional capability of the State of Oregon to manage the territorial sea under its jurisdiction recently was examined by the authors. Oil and gas development, marine mineral mining,...
Management Responses to Technical Uncertainty
Recent attention to management and regulation of contaminated waste materials has served to heighten awareness of the role of technical uncertainty in regulatory decisionmaking. Two distinct,...
The ARC Reefs: Designed Artificial Reef Systems
Results of laboratory tests and preliminary results of field tests indicate materials and designs incorporated in The American Reef Corporation (ARC) designed artificial reef structures...
Oil and Krill: From Lab to Nature
Bioassay tests were conducted on Arctic krill, the euphausiid Thysanoessa raschii, using water-soluble fractions of Prudhoe Bay, Alaska crude oil. Experimental results indicated that larval...
