Environmental Mitigation Techniques for Marina Development
The paper discusses a coastal design process entitled 'Design by Mitigation'. It describes a series of mitigation measures and techniques which can be used to...
Mitigation Features for Marinas
The John Wayne Marina was permitted for construction only after certain design features were altered to accommodate major biological and water quality concerns. The moorage basin was relocated...
Innovations in Dredged Material Disposal in Puget Sound
This study, known as the Puget Sound Dredged Disposal Analysis (PSDDA), is building on a strong history of federal/state cooperation within Washington which is unique in the United States....
Economical Solutions for Dredged Material Disposal
During the 1970's, the State of Wisconsin expressed concern about contamination of dredged materials and the deposition of pollutants into Wisconsin's Great Lakes...
An Innovative Solution to the Difficult Coastal Zone Management Problem of Dredge Material Disposal
The New York Power Authority is constructing a 300 km predominantly double circuit 345kV transmission facility through southeastern New York State. A key element in this project is the...
Aquatic Dredged Material Disposal in New England
The Disposal Area Monitoring System (DAMOS) is a large multi-disciplinary environmental monitoring program instituted by the New England Division (NED) of the U. S. Army Corps of Engineers...
Use of Sediment Bulk Chemistry Data for Dredged Disposal Management in Puget Sound
Although no fully scientific approach for setting and interpreting sediment chemical levels is currently available, an effects-based approach for using bulk chemistry data was evaluated...
Protocol for Deep Ocean Disposal Monitoring
Deep ocean sites are presently being considered for the permanent disposal of wastes. The Environmental Protection Agency (EPA), in conjunction with other agencies, is mandated to monitor...
Assessment of Beach Nourishment Methodoliogies
Although artificial beach nourishment has become a common practice for mitigating beach erosion in the U. S. , it lacks clear rationales for achieving optimum benefits. Four recent large-volume...
Coastal Zone Management Practices, Northwest Brittany, France
Over the entire coast of Brittany, three government programs have sponsored over 81. 9 million francs (6 ff equals US1, approx. ) of coastal-related programs since 1968. Projects vary...
Oil Pollution in Suexz Gulf of the Red Sea
The population along the Red Sea coast is small, but this sea is now one of the most important areas in the world, for it is the route for ships using the Suez Canal. Many vessels transit...
Sea Level Changes: A Corps of Engineers Perspective
The purpose of this discussion paper is to review current Corps of Engineers policy in relation to a possible significant increase in general sea level. A significant relative sea level...
Site Characterization for Waste Disposal
Site selection is one of the key decisions in waste management. Site selection involves a conflict analysis which considers various engineering factors including geotechnical, as well...
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...
Plastic Concrete Cutoff Walls
The studies revealed that plastic concrete can be prepared having a coefficient of hydraulic conductivity that is less than 1 multiplied by 10** minus **7 cm/sec. The shear strength of...
Quality Control Testing for a Sand-Bentonite Liner
This paper presents the results of the quality control testing performed during the construction of a sand-bentonite liner for a sanitary landfill site in Central Florida. The available...
Acceptance Sampling for Clay Liner Design
The assurance of the quality of constructed clay liners has been a problem for geotechnical engineers. Compliance with minimum standards is necessary to ensure the liner performance capability....
Permeability of Compacted Clay Liners in Laboratory Scale Models
Experiments conducted in flexible wall permeameters have shown that the permeability of a soil sample is dependent on the size of the specimen tested. The permeability was found to decrease...
