Tying Back a Landslide
A slope covered with landslide debris is never the most desirable site on which to build, but sometimes it is the only one available. For the Forks of Butte hydroelectric power project,...

Ocean Energy Recovery
the State of the Art
This book, Ocean Energy Recovery: The State of the Art, establishes the state of the art in the full range of renewable energy technologies....

Safety Factors, Loads, and Impact
The loads given in this chapter are intended for general guidance only (including wind, ice, stream flow, etc.). Maximum deflections and rotations may likewise vary with national codes....

Dynamic Wind Loads
This chapter is concerned with the motions of cable stayed bridges that arise as a result of wind action. The aerodynamic phenomena that must be considered are vortex shedding, torsional...

Analysis of Waterbody Surface Heat Exchange
The Edinger-Duttweiler-Geyer (EDG) approach for estimating heat exchange at a water surface was examined and its applicability to ice-covered waterbodies determined. The EDG linearized...

Designing for Control of Ice Conditions in Marinas
Each marina or small-craft harbor experiencing ice during the winter months must be designed for site specific conditions. These conditions are governed by environmental factors (geology,...

A Shallow-Draft Icebreaker for the Upper Niagara River
The New York Power Authority (Authority) designed and built a special purpose, shallow-draft icebreaker in 1986 and 1987 for use in the upper Niagara River. The icebreaker is used during...

Wind Tunnel Modeling of Time-Dependent Drift Topography
The aeolian wind tunnel is a useful tool for investigating not only the saltation physics of wind-driven sand, soil or snow, but also for determining the time-dependent development of...

Drifted Snow on Roofs
Drift snow loads on multilevel roofs account for about 75 percent of all snow load related roof collapses. A case history of snow drifts provides the foundation for a discussion of the...

Snow Transport as a Function of Wind Speed and Height
When limitations are placed on mass flux in the saltation layer, a regression equation relating mass flux to wind speed and height above surface, developed by Mellor and Fellers (1986),...

Wind Power in Antarctica?Case Histories of the North Wind HR3 Wind Turbine
The combination of extreme weather conditons and remoteness of the Antarctic sites makes them even better suited for wind turbine installations since the alternative power sources are...

Valuing Residual Emissions in Electricity Planning
Incorporating the valuation of residual emissions into calculations of social cost permits comparisons among alternative sources of electricity generation inclusive of environmental impacts....

Precipitator Retrofit and Repair: A Case Study
Described is a difficult fossil power station retrofit project performed on a tight schedule at a congested site. Installation of a new supplementary precipitator and structural repairs...

Retrofitting Existing Fossil Plant Facilities
This paper summarizes the contents of and provides some insight into the usefulness a structural engineer will get from the publication 'Retrofitting Existing Fossil Plant...

Hydrogen?The Clean Fuel of Tomorrow is Available Today
This paper examines the role of fossil fuels and advocates a proactive energy policy to stimulate the use of domestically produced 'clean' energy carriers (fuels),...

The PowerBargeTM for Lock/Dams on Inland Waterways
Following a brief description of the prefabricated floating PowerBarge concept, the range of application and expected cost and time savings is presented. Environmental benefits are described...

Preliminary National Evaluations of CO2 Emission Controls
Under the aegis of the International Energy Agency, several countries have begun making comparable studies of the cost-effectiveness of various measures to reduce emissions of carbon dioxide...

Exploring CO2 Emissions Reduction Strategies
Concern for potential climate change resulting from the greenhouse effect may be the biggest factor in energy planning in the 1990s. A 20% reduction in CO2,...

Electric Utility Planning for Greenhouse Concerns
International concerns for the potential of significant climate change resulting from the greenhouse phenomenon have focused increasing attention on the emissions of carbon dioxide and...

Procedure for Seismic Evaluation and Design of Small Bore Piping
Simplified methods for the seismic design for small bore piping in nuclear power plants have been used for many years. Various pipe designers have developed unique methods to treat the...
