Breakwater Breakthrough�Bold New Breakwaters
A new rubble-mound breakwater design is a departure from the conventional approach detailed in the U.S. Army Corps of Engineers Shore Protection Manual. The new concept, called the berm...
Monitoring for Hazardous Waste Leaks
It is safer and cheaper to keep hazardous wastes out of the groundwater and the ground than to remove them. But better monitoring will be required. In this three-part article, the first...
Courting Public Opinion
Promoting good community relations is an integral part of hazardous waste projects. Before field investigations are conducted, neighboring communities should be advised of the proposed...
A Watery Grave
Subseabed disposal may be the most acceptable means of dealing with radioactive wastes. Land disposal sites are difficult to find and politically difficult to use. Little research has...
Probabilistic Site Strategy for Transmission Lines
A probability-based geotechnical site characterization strategy is presented for transmission line structures. Because site-specific data are sparse for these structures, a Bayesian model...
Investigation of Excavatability in the Piedmont
The lateral and vertical variability of rock weathering in the Piedmont presents significant problems in evaluating the probable cost of excavation for deep basements, pipeline, road cuts,...
Dispersive Soil and its Influence on the Design of Reach 1A of the Tucson Aqueduct?Central Arizona Project
An extensive geotechnical field exploration and laboratory testing program was conducted because of dispersive and erosive soils along the alignment of the canal. The canal design was...
Survey of Groundwater Contamination in Massachusetts
Public water supplies in Massachusetts have been contaminated or threatened from a number of sources. The purpose of this paper is to outline the nature of groundwater contamination and...
A Call for New Directions in Drilling and Sampling Monitoring Wells
The hollow-stem auger drilling technique has an inherent limitation of disturbing large volumes of subsurface materials around the borehole, thereby possibly affecting local permeabilities...
Control of Groundwater Contamination: Case Studies
Engineered solutions to groundwater contamination problems are being proposed at many hazardous waste sites, yet the effectiveness and long-term reliability of many of these proposed solutions...
Emergency Response
A spill normally has five phases; namely, the initial emergency response, the site assessment, the development of a remedial action plan, the implementation of the remedial action plan,...
When to Remediate: Remediation or Reparations
The 1986 reauthorization of the Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) forcefully stated Congress' desire to see our nations hazardous...
Physical and Chemical Treatment of Contaminated Groundwater at Hazardous Waste Sites
In selecting an appropriate groundwater treatment system, three steps are normally followed. 1. A groundwater investigation is performed to determine the types and concentrations of contaminants...
The Impacts of CERCLA, RCRA and State Programs on Site Remediation: A Case Study
The major federal programs requiring ground water remedial response actions include RCRA and CERCLA. On the state level New Jersey law makers have enacted a number of statutes which regulate...
Environmental Considerations to Channel Dredging
In this paper two principal areas of environmental concern were investigated. The first is the physical impact of dredging and deposition of solid materials causing turbidity on aquatic...
Construction of Fisherman's Wharf Breakwater
The San Francisco District of the United States Army Corps of Engineers recently completed construction of a breakwater at Fisherman's Wharf. The construction, completed ahead...
Quantification of Net Shore-Drift Rates in Puget Sound and the Strait of Juan de Fuca
The objective in this study was to determine the annual rate of net shore-drift at selected sites within Puget Sound and the Strait of Juan de Fuca. These sites were selected based on...
A Wetland Habitat Assessment Method using Birds
A wetland habitat assessment technique (HAT) using birds as indicators of habitat quality was developed from the method of V. R. Holmes et al. , (1986) and J. W. Graber and R. R. Graber...
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...
California's Retreating Shoreline: The State of the Problem
Approximately 86 percent of California's 1715 km of shoreline is eroding. Nearly ten percent of this oceanfront has now been armored. With present day costs of shoreline protection...
