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...
Effects of Erosion on Soil Productivity
Erosion-caused crop production decreases up to 50% have been measured with decreases of 15 to 30% commonly reported. Furrow erosion on irrigated land redistributes topsoil, decreasing...
Management Practices for Erosion and Sediment Control in Irrigated Agriculture
Basin irrigating rice can reduce suspended sediment loads in water because the basins serve as sediment retention basins. Furrow erosion causes significant suspended sediment loads in...
Water Supply Infrastructure Needs: The Evolving Picture
Based on the findings from AWWA surveys conducted in 1983 and 1985, it appears that the earlier conclusion that the needs of the nation's water systems can be met by the local...
Converting a Mainframe Erosion Simulation Model to a Microcomputer Software
In this paper, techniques for mainframe to micro conversion are discussed. As a practical case, an erosion simulation model was used. The created software predicts distribution of erosion...
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...
The Assessment of Freeze-Thaw Damage in Cement Stabilised Soils
Whilst the ASTM Freeze-thaw test was not originally conceived as a means for classifying the frost resistance of cement stabilised soils it has become accepted for this purpose, with the...
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...
Boston's Water Resource Development
Past, Present, and Future
This volume contains five papers describing diverse aspects of water supply, water power, and wastewater disposal in eastern Massachusetts. Three papers discuss Boston's water...
Leak Detection Is Just a Piece of the Pie
This paper emphasizes that leak detection is part of the proper management techniques that must be used to control unaccounted-for water. In order to effectively understand the pieces...
Boston's Future Water Supply
The Massachusetts Water Resources Authority is responsible for planning and providing water to metropolitan Boston. Recent state legislation directs that conservation, development of local...
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....
