Drilled Piers in the Piedmont?Minimizing Contractor-Engineer-Owner Conflicts
Drilled piers are used extensively in the Piedmont Physiographic Region, deriving support primarily from end-bearing on hard rock. Cost extras and contractor-engineer-owner conflicts are...
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...
The Delineation and Management of Wellhead Protection Areas
The delineation and protection of a management zone around specific wells or wellfields will undoubtedly become more common as the 1986 Amendments to the Safe Drinking Water Act are implemented...
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...
Optimal Process of the Development of the Residential Area on the Coastal Zone
The concentration of population and assets through various types of development in the coastal zone in Japan is progressing rapidly at present. The conditions of the sea environment are...
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...
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...
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...
Integrated Monolayer Flexible Revetment Technology for Coastal Protection
Fundamental considerations for flexible revetment design are given in some detail and the critical need for sound engineering in a total system design approach is strongly emphasized....
Pass a Loutre Freshwater Diversions: Marsh Building in the Mississippi River Delta
Concern about the rapid loss of wetlands within the Pass a Loutre Wildlife Management Area located at the mouth of the Mississippi River has resulted in implementation of the Pass a Loutre...
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...
