This paper addresses different aspects of exporting the American knowledge and experience in the private development of small-scale hydropower projects. It details the 'export'...
Technology Transfer for Small Hydro
The wide range of different definitions of what constitutes a small hydroelectric power plants is discussed and the conclusion is drawn that this definition should be based more on the...
Evaluating Hydro Project Benefits with the POWRSYM Production Cost Model
The contribution that a hydro peaking project or pumped-storage project makes to reducing system operating costs can be determined only by modeling the project's operation...
Outlet Works Modifications at Abiquiu Dam
For the installation of a hydroelectric project at the Corps of Engineer's Abiquiu Dam in New Mexico, outlet works modifications that would not affect the structural integrity,...
Evaluating History?The Edison Sault Powerhouse
The hydroelectric facility owned by the Edison Sault Electric Company at Sault Ste Marie, Michigan was an engineering marvel when it was designed and constructed. This paper explores the...
Generation Control Methods for Operating Efficiency Improvement
One way to increase the energy production of a hydroelectric powerplant is to improve the power production efficiency, that is, obtain more energy for a given quantity of water through...
Case Study in the Upgrade and Rehabilitation Techniques of a Pumped Storage Installation
This paper presents a specific case study in the runner upgrade and unit rehabilitation of two pump/turbines at the Seneca Powerhouse. The study addresses the modern optimized designs...
Overview and Objectives of the Macrodispersion Experiment
TVA is conducting large-scale field experiments to better define movement and dispersion of contaminants in groundwater. This will support groundwater protection by making possible more...
Second Natural-Gradient Tracer Experiment
The Tennessee Valley Authority (TVA) has begun a second large-scale groundwater field experiment at the Columbus Groundwater Research test site in Mississippi. This research is a continuation...
Practical Technology Resulting from MADE Research
As is often the case, when theoretical research is performed, practical technology is developed in the process. This has occurred with the Macrodispersion Experiment (MADE) conducted at...
Influence of the Deposition of Anthropogenic Organic Substances from the Atmosphere on Ground-Water Quality
Large amounts of organic substances are emitted into the atmosphere as a consequence of human activity. The primary emissions as well as their atmospheric reaction products reach the soil...
Pump Station/Storage Opportunities for Urban Freeway Systems
This paper introduces the concept of utilizing underground storage to minimize both the initial cost and the long-term maintenance and operation costs of multiple pump stations for a freeway...
Innovative Reregulation Weirs for Dam Releases
Two different reregulation weir designs for dam release improvement are discussed. A porous timber crib is favored for applications where increased minimum flow is needed, and a labyrinth...
Bridge Scour Vulnerability Assessment
Although the failure of the New York Throughway bridge over Schoharie Creek in 1987 has focused national attention on scour related failures, other failures reinforce the need for implementing...
Local Resources in Developing Country Water Supplies
Maximizing the use of local resources in water supply projects can expand markets for locally produced equipment and materials, reduce exports and minimize expenditures of hard currency...
Using Social Infrastructure in Support of Appropriate Technology
This paper proposes and argues for an expanded definition of social infrastructure, suggesting that the creation, adoption and maintenance of appropriate technology are dependent upon...
Appropriate Technology in Infrastructure Development and Management
Infrastructure management principles apply to appropriate technologies used for hydraulic structures. However, some of the principles are more culturally sensitive than others, mainly...
Energy Losses Due to Air Admission in Hydroturbines
Admission of air at the exit of a hydroturbine runner is an attractive technique for raising dissolved oxygen levels downstream of a hydro plant. The air admission, however, is generally...
Liabilities in Temporary Structures Failures?Representative Case Histories
Eight case studies involving construction accidents caused by failure of temporary structures are presented. These studies illustrate the oftentimes unintended consequence of utilizing...
FHWA'S Bridge Temporary Works Research Program
The Federal Highway Administration (FHWA) has developed a research program to address bridge falsework design and construction. This resulted from the collapse of the Route 198 bridge...
