Albemarle-Pamlico Sounds: Issues, Resources, and Management (
The Albemarle-Pamlico Sound complex, located in northeastern North Carolina, is the third largest estuarine complex in North America and the second largest in area in the United States....
Barrier Beach Management: The Long Island Experience
Barrier beaches are intrinsically unstable but are used for a variety of human activities ranging from recreational to commercial use. This type of land use often leads to the demand for...
Bulkhead Instability in Soft Soil
This paper presents a case study involving the severe disturbance of the subsurface soils in front of an existing bulkhead caused by the berthing of a jack-up type, offshore drilling vessel....
Ocean Erosion Control for the Private Sector
The paper describes some procedures of design and construction of riprap type protective structures to contain ocean erosion and to provide an end product that both gives protection and...
Nearshore Sand Sources for American Samoa: An Alternative to Using Beach Sand
Using a combination of geophysical techniques, in situ observations, and sampling by scuba divers, we investigated along the south shore of Tutuila Island, American Samoa, for nearshore...
Coastal and Marine Resource Management Prospects in Somalia
The main coastal resource management issues in Somalia are centered in the terrestrial component of the coastal zone. There are no significant problems of marine pollution or the overexploitation...
Sand Rights, a Legal System to Protect the Shores of the Sea
The legal system of water rights in California is highly developed. So far, however, it has failed to recognize in any comprehensive fashion the importance of the sand which is transported...
Earthen Liners for Land Disposal Facilities
Proper construction of compacted earthen liners requires special attention to construction details and quality assurance. Moisture content and weight of roller are probably the two most...
Design of Geosynthetic Systems for Waste Disposal
Geosynthetic materials (consisting of geotextiles, geomembranes, geogrids and geocomposites) are currently being used in large amounts to contain solid wastes in landfills, surface impoundments...
Chemical Effects on Clay Hydraulic Conductivity
Hydraulic conductivity and its susceptibility to changes with time or exposure to chemicals are major factors in selection of clay for use in waste containment barriers. Available concepts...
Design and Performance of Earth-Lined Containment Systems
Engineers have been designing and constructing earthen containment structures for many tens of years. These structures have historically been embankment dams, petroleum storage impoundments,...
Ion Transfer by Diffusion Through Clayey Barriers
The practical aspects of pollutant migration by diffusion through clayey barriers is presented. The discussion is generally restricted to soils of pH approximately equals 8 which contain...
Pollutant Transport Through Barriers
Methods of predicting contaminant transport through saturated and unsaturated clayey barriers are reviewed. Particular consideration is given to the relative importance of advection and...
Vertical Barriers in Soil for Pollution Containment
Vertical barriers have evolved over the past fifteen years into a technique that is widely applied to restrict the underground movement of liquid wastes and polluted groundwater. Most...
Movement of Nonaqueous Liquids in Groundwater
Evidence from field sites indicates that when nonaqueous liquids, such as organic solvents and gasoline, are released into the subsurface environment they tend to remain as a separate...
Assessment of Pore Fluid Effects Using Flexible Wall and Consolidation Permeameters
Hydraulic conductivity tests were conducted on compacted soil specimens prepared at activities of 0. 36, 0. 60, 1. 00 and 1. 39 at a fine fraction of 25 percent. Na-montmorillonite, Georgia...
Containment of Low-Level Radioactive Material
The U. S. Department of Energy has completed a short term storage site for the containment of low-level radioactive residues and contaminated soil near Lewiston, New York. The site, known...
Landfill Stabilization for Structural Purposes
The insitu stabilization of landfills and waste disposal sites for structural and environmental purposes has recently been accomplished through the application of existing soil stabilization...
Erosion of the Slopes of Gold Tailings Dams
A study has been made of rates of erosion from the slopes of gold-residue dams in the South African Highveld region. Data is available for two years at this time and conclusions must therefore...
Stabilized Fly Ash for Use as Low-Permeability Barriers
Two class F fly ashes from power stations located in West Virginia were stabilized by adding various percentages (by weight) of either lime or cement. Test specimens were subjected to...
