Field Instrumentation Program Vital to Deep Excavation Project
An extensive field instrumentation, monitoring and evaluation program was implemented for a seven-level deep excavation project in Boston. Using the observational approach, the information...
Data Acquisition and Test Control in the Laboratory
With the progressive development of microcomputer technology, microcomputer based data acquisition systems have become an indispensable tool in the soil mechanics laboratory. This paper...
Spatial Variation in Liquefaction Risk Assessment
Basic concepts and methods of random field theory, needed to characterize 'distributed disordered systems', are reviewed and applied to a soil liquefaction case...
Roof Wind Damage Mitigation: Lessons From Hugo
Hurricane Hugo caused extensive roof damage in Charleston, South Carolina and surrounding areas. Extensive field investigations have revealed the causes of many of the problems. This paper...
Field and Numerical Investigations on Siltation Mechanism in Kumamoto Port
Synthetic investigations on siltation mechanism in Kumamoto Port were carried out by field observations, laboratory tests, and numerical simulations. Natural conditions such as tides,...
Results from Selected Oil-Spill Response Research
Recent large oil spills from tankers have reaffirmed the need for continuing technology assessment and research to improve oil-spill response capabilities. The Minerals Management Service...
Shoreface Connected Ridges Along the Dutch Coast
Quasi-synoptic current measurements were obtained across the Dutch shoreface connected ridges using an acoustic Doppler current profiler. The measurements are used to evaluate the role...
Chesapeake Bay Field Modeling and Monitoring Projects
'Traditional' erosion control measures often do not meet the Corps of Engineers' requirement for economic justification. The costs of these measures...
Field Application of a Numerical Model of Beach Topography Change
Discussion was made, on the basis of field data, on the applicability of the formula for local rate of sediment transport due to combined action of waves and currents presented by Watanabe...
The Interaction of Seawalls and Beaches: Four Years of Field Monitoring, Monterey Bay, California
Coastal protection structures have historically been the most common approach to dealing with the problem of shoreline erosion in the United States. Three potential impacts of these structures...
Cross-Shore Sediment Transport Determined by EOF Method
Laboratory and field data of beach profile changes are used to study the cross-shore transport rate. The Empirical Orthogonal Eigenfunction analysis is applied to separate the temporal...
UV Disinfection of Wastewater: A Pilot-Scale Study of Performance
A pilot-scale study of UV disinfection under field conditions was conducted. Inactivation and photoreactivation was well correlated with UV dose. Standards of 100 coliform/100 mL were...
An Integrated Study of Air Toxics Emissions from an MSW Landfill
An integrated approach was used for a study of air toxics emissions at a municipal solid waste (MSW) landfill (LF) consisting of field sampling, emission estimation, atmospheric dispersion...
Evaluation of
This paper examines the potential application of in-situ bio-dentrification as well as pertinent physical and biochemical factors that control the process to reduce nitrate in groundwater...
Numerous releases of hazardous substances have occurred at uncontrolled sites all around the United States. These sites pose toxic threats to public health and our environment, and potential...
Magnetic Fluid Conditioning
Industry is now turning to develop magnetic water treatment in an effort to discontinue the use of chemicals. Magnetic water treatment takes a different approach to solving the same problem...
Fish Protection at Water Intakes Using a New Signal Development Process and Sound System
American Electric Power Company, Inc., is exploring the feasibility of using a patented signal development process and sound system to guide aquatic animals with underwater sound. Sounds...
Varying Generator Excitation to Control Draft Tube Surge
The Bureau of Reclamation recently experimented with varying the excitation applied to a hydroelectric generator to control power swings caused by draft tube surging in a Francis turbine....
Field Tests of a Lewiston Pump-Generating Unit
An extensive field test program was undertaken on a Lewiston Pump-Generating Plant (LPGP) unit at the Niagara Power Project, owned and operated by the New York Power Authority. The objective...
Evaluation of Turbine Intake Velocity Criteria
The paper addresses the effect of intake flow distribution on turbine performance at low-head projects. Field and model test data are used to raise the question of whether typical turbine...
