In Situ State of Underwater Hydraulic Sand Fills
An approach is described for quantifying the in situ state of hydraulically placed sand fills which are a significant element in the construction of artificial exploration islands in the...

A Contractor Looks at Slope Protection for Arctic Offshore Artificial Islands
Some thirty artificial gravel islands for oil and gas drilling/production have been built in the Beaufort Sea since early 70's. Protection of slopes of the islands and causeways...

Determining Soil Properties by Electric Cone Penetrometer
Gravel island construction is one primary means of establishing permanent locations for oil wells, building foundations and road beds in the arctic. The gravel provides a natural insulation...

Influence of Artificial Island Side-Slopes on Ice Ride-Up and Pile-Up
An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms...

Three-Dimensional Analysis of an Artificial Island
A nonlinear, finite element analysis has been carried out to investigate the influence of three-dimensional loading and geometry on deformation and failure of an artificial island. The...

Ice as a Construction Material in the Offshore Arctic
Ice is the most available and abundant material in the offshore Arctic, and it is therefore one of the most cost-effective construction materials. Over the past decade, ice has been used...

Jumbo Modules for Artificial Islands
The development of the Arctic Offshore oil fields has led to the consideration of gravel islands or other structures to support oil production facilities. The island and the assembly site...

Geotechnical Design of Caisson Islands
There are a number of areas where fundamental geotechnical research is required so that non-conservative, rational and safe design of artificial exploration islands can be achieved. Some...

Prediction of Highway Construction Noise Levels
A model for the prediction of noise levels from highway construction operations has been developed under sponsorship of the Federal Highway Administration (FHWA). Noise sources are geometrically...

Highway Noise: FHWA Requirements and Barrier Design
Since 1973, the Federal Highway Administration (FHWA) has required noise studies for nearly all proposed roadways and roadway improvements that receive federal aid. An overview of these...

Standardizing Noise Barrier Field Measurements
American National Standards Working Group S12-6 was organized in 1979 to draft a standard for the acoustical measurement of outdoor noise barriers. The current version of the draft standard...

Quali-Continuous Simulation of CSOs
Providence, Rhode Island, has a combined sewer system. During and following a precipitation event the capacity of the system may be exceeded and a mixture of wastewater and urban runoff...

The Protection and Management of Cultural Resources Through State Coastal Management Programs?A North Carolina Case Study
North Carolina's coastal management program attempts to protect and manage a broad spectrum of the state's coastal resources. These resources range from valuable...

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...

Changes in Wading Bird Habitat on Georgia Islands
Free flowing artesian wells were developed in Georgia during the late 1800's. Some of these wells produced important habitat for colonially nesting wading bird populations....

Nantucket's Endangered Maritime Heaths
Heaths, though common in northern Europe, are of disjunct distribution and limited development on the east coast of North America. In contrast, Nantucket Island, Massachusetts supports...

Man-Made Offshore Islands: An Innovative Solution to Coastal Erosion
Existing shore-parallel detached breakwaters have resulted in the accretion of sand along the shoreline in the wave shadow of the structure. Significant prograding of the beach has replaced...

The Use of Thematic Mapper Data for the Identification and Analysis of Small Island Land Covers: The Case of Block Island
This paper describes the classification (unsupervised) of a portion of the Landsat Thematic Mapper (TM) scene covering Block Island, Rhode Island and surrounding waters. The Landsat system...

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...
