Calibrating a 2-D Fate and Transport Model of Watts Bar Reservoir
A branched two-dimensional water quality model has been developed and tested for the Watts Bar Reservoir, including the Clinch River and Emory River embayments. The general stratified...
Effectiveness of Wet Detention and Retention Ponds for Improving Stormwater Quality
The most commonly used structural measures for stormwater quality management and control are retention basins, wet detention ponds, and detention with filtration ponds. This paper explores...
Utilization of Expert Systems for the Operation of Reservoir Systems
This paper illustrates how knowledge-based expert systems can obtain, organize, document, store, and utilize valuable complex reservoir systems experience, obtained by experienced water...
Localized Mixing for Improvement of Hydropower Releases from J. Percy Priest Reservoir
The J. Percy Priest Project, located on the Stones River near Nashville, TN, experienced low dissolved oxygen (DO) in the tailwaters during hydropower generation. Using commercially available...
Flushing Flow Analysis Concepts
Many environmentally oriented groups who oppose water resources projects, have conceived various types of flow requirements to supposedly meet a variety of biological purposes in rivers....
Automation of Existing Dam Control Schemes
For installations that are already in operation, the following advantages are obtained from installing new electronic equipment: In the case that the dam or certain measuring stations...
World Class Manufacturing and Hydro-Electric Production
Operations, maintenance, and administration and support services can benefit from the concepts of World Class Manufacturing. Cellular organizational concepts whether its machines, people,...
Licensing the Moose River Hydroelectric Project
This paper describes environmental considerations in the licensing and permitting of the Moose River Hydroelectric Project, a 12.2 MW development in Central New York State. It illustrates...
Utility Options for Meeting Dissolved Oxygen Limits for Hydroelectric Power Plant Discharges
Due to increased attention by regulating agencies to the dissolved oxygen levels of water released through hydroelectric power plants, the Electric Power Research Institute has developed...
Improvement of Dissolved Oxygen Levels at Shepaug Hydro Station
Discharge from Shepaug Dam in Connecticut fall below the state standard for dissolved oxygen in summer and early fall, because of thermal stratification of the upstream eutrophic reservoir....
Water Quality Studies for Hydro Licenses
Three case studies on the impact of hydro operation on dissolved oxygen concentration performed for hydro license applications are utilized in a discussion of water quality issues. A negative...
A Water Quality Impact Analysis of a Hydropower Facility
A low-head hydropower generating facility has been proposed at an existing dam site on a river. The state environmental agency has required an environmental evaluation into the potential...
Balancing Hydropower Development in the Ohio River Basin
A large number of retrofit hydroelectric projects have been proposed at existing navigation dams in the Ohio River basin. These proposals involve potentially adverse environmental impacts,...
Optimizing Joint Load Control for Hydroelectric Plants
This paper discusses a method to minimize water usage at a multi-turbine hydroelectric generating plant. At plants which do not spill water this optimization is directly converted to extra...
Replacement of Computer Control at John Day Powerhouse
One of the first projects chosen by the Corps of Engineers for computer control was the John Day Project on the Columbia River. John Day powerhouse was completed in 1971 and has 16 generators...
Distributed Control Applications for Utility Hydroelectric Plants
In 1984, Washington Water Power began a program to improve monitoring and control systems for hydroelectric plants. The control systems being improved with distributed control equipment...
