Coupling Free Vortex Energy Dissipation with Sediment Control
The paper reports on studies showing that sediment control down to the abrasive limit of 30 micron sand and energy dissipation can be achieved simultaneously with a Teacup free vortex...

Plunge Pool Energy Dissipators for Some Dams in Taiwan, ROC
This paper presents a brief description of the characteristics of the plunge pool type energy dissipators, including design considerations, hydraulic model tests, as well as the results...

Phreatophyte Water Use Estimated by Eddy-Correlation Methods
Water-use was estimated for three phreatophyte communities: a saltcedar community and an alkali-Sacaton grass community in New Mexico, and a greasewood rabbit-brush-saltgrass community...

Energy Dissipation in Small Canals
Two approaches are used for energy dissipation in channels. In the first, the water is allowed to drop, thereby converting potential energy to kinetic energy. This excess energy is then...

Urban Energy Systems for the 21st Century: Transition Paths
Alternative energy systems can be expected to be a significant part of advanced, 'intelligent,' infrastructure systems for cities of the 21st Century. The question...

Technology Assessment for Hydrogen from Renewable Energy
This paper is a preliminary report on an assessment of technologies for hydrogen production from renewable resources, and an investigation of the problems and issues involved in assimilating...

Hydrogen Energy for Residential/Commercial Sector
Hydrogen is being considered as a synthetic fuel or energy carrier for the post fossil fuel era. It has many properties to commend itself: It compliments the non-conventional primary energy...

New Generation Capacity
Currently, electric utilities in the U. S. have excess generation capacity. In addition, some new generation capacity is well under construction and is scheduled to come on-line soon,...

A Power Planning Model for Seismic Risk Zones
We present a model to configure a nuclear power system consisting of plants and the distribution network. In the model, we quantify seismic risk as comprehensively as possible in terms...

Developing Renewable and Alternative Energy Sources
The development of small scale, renewable or alternative (R/A) energy resources was originally perceived as environmentally more acceptable than large-scale conventional projects. The...

Energy Systems for the 21st Century
The papers in this book review problems and possibilities of emerging energy technology for the future. One paper discusses the world energy outlook and the political and economic barriers...

World Energy Outlook
In response to lower energy prices and reinvigorated economic growth, demand for all forms of energy is increasing steadily. With the growing realization that man's resources,...

Improved Urban Traffic Flow Through Signal Re-timing?California Experience
The California Energy Commission (CEC) has initiated a new program to re-time all of the 20,000 interconnected traffic signals in the state, the first of its kind in the United States....

Environmental Permitting Approaches for Future Development of Offshore Oil Fields in the Arctic
Environmental impact of petroleum prospecting on the North Slope of Alaska is complicated by climatic problems of long periods of low temperature and thick ocean ice. Better engineering...

Bowhead Whales and Other Endangered Whale Species: Their Influence on Offshore Operations in Alaska
In recent years, whales have become the focus of considerable public concern, and this is manifested in the measures that are imposed to protect them from possible adverse effects of offshore...

Bering Sea Crude Oil Transportation Systems
A study to evaluate and compare the technology and costs associated with crude oil transportation alternatives in the Bering Sea has been conducted. Existing and proposed offshore loading...

Decentralization of Nuclear Power Plant Engineering
The cost of nuclear power construction in the past two decades has increased by an order of magnitude, forcing utilities and A/E's to look for ways to reduce engineering and...

Modifications At Operating Nuclear Power Plants
In these days of continuing regulatory requirement changes and high interest rates, the engineering of structural modifications for operating nuclear power plants has taken on greater...

A Model for Nuclear Waste Shipping and Storage
A management option for spent fuel assemblies from nuclear power plants is storage in away-from-reactor (AFR) storage facilities. The purpose of this paper is to preseent a new mathematical...

Oconee Spent Fuel Rerack
Spent fuel storage problems facing electric utilities with nuclear generation are growing more critical as existing spent fuel storage capacity is utilized. Due to the inaccessibility...
