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...
Simulations of Multireservoir System Operation
Simulation modeling has evolved from a direct examination of operating policies into operational decision support systems, integrated multiple use expansion planning systems and special...
First 10 Years of Operation of
The first turbine of the La Grande hydroelectric Complex (Quebec, Canada) was commissioned in october 1979. Since then, five reservoirs, two rivers diversions, three power stations with...
Sediment Evacuation System for Impounded Rivers
Current solution techniques for the reservoir sedimentation problem are presented and their rationale questioned. The need for focusing on the overall river transport regime is emphasized....
Some Pertinent Considerations in Dam and Reservoir Design
Two important considerations in designing and constructing a multipurpose earthdam and reservoir are to minimize losses in the event of dam failure because of overtopping, and to conserve...
How Many Years to Fill with Sediment, a Sediment Study of Lake Powell on the Colorado River
A study to determine the current capacity and to update information on the life expectancy of Lake Powell was conducted by the Bureau of Reclamation. The study documented the present storage-elevation...
Intake Towers and Outlet Tunnels Adapted for Hydro
An intensive design project was undertaken with the objective of retrofitting two U.S. Army Corps of Engineers (COE) dam sites for hydroelectric power generation. The challenge of designing...
The Modification of Leroy Anderson Dam
An extensive modification program has been implemented to improve the safety and enhance the performance of the Leroy Anderson Dam. The Leroy Anderson Reservoir has a maximum storage of...
Optimization of Power Production Based on Efficiency Data
Computer programs dealing with different parts of the optimization process are in operation in Norway today, and they include: the hydrological part from weather forecast to reservoir...
Manicouagan 5?Additional Capacity Project
This paper, after presenting briefly the evolution of the peak demand characteristics of the Hydro-Quebec grid and what caused it, describes how newly installed capacity and equipment...
A Non-Federal Development at a Federal Project
The Colebrook River Lake project is a Corps of Engineers multipurpose reservoir located in northwestern Connecticut. The hydro project, designed and built by the Catalyst Energy Corporation...
Pumping System Permits Diversion of Water River Dam
For project construction at an existing Corps of Engineers' dam in New Mexico, where modifications to the existing outlet works were performed, a barge-mounted pumping system...
Modeling Sedimentation Problems at Hydro Developments
Sedimentation embodies the processes of erosion, transportation and deposition of sediments. At hydro developments, sedimentation can create problems. Computer sedimentation models (CSM's)...
Knowledge-Based Expert System for the Real-Time Operation of Reservoir Systems
An efficient way to avoid the loss of valuable knowledge is to develop an expert system which incorporates hydrologic, hydraulic, system analysis, environmental, economical knowledge based...
Hydro on Hold
Hydropower projects have become the target of a growing environmental movement overseas. The tradeoff between clean, renewable energy and the possible environmental impacts of the reservoirs...
Rx for Dam Repair
Bernard asserts the growing importance of maintenance to extend the service life of dams as more and more of them reach or exceed their design lives. He describes renovations to Easton...
Project Alternatives to Benefit Endangered Species
In April 1986, the Missouri River Division, U. S. Army Corps of Engineers, determined that operation of the main stem system had the potential to adversely affect the listed species. Consultation...
A Short-Term Hydro Scheduler for Hydro-Thermal Power Systems
This paper presents HYDSIM (Hydro-electric Simulation), a new versatile computer model developed to simulate the hourly or daily operation of a large network of multi-purpose reservoirs...
Managing for Multiple Uses?Theory and Practice
One of the gratest challenges given to reservoir operators is to provide an operating regime that will accomplish the objectives for which the project was constructed. This is important...
Reservoir Regulation in the Monsoon Climate of Korea
An examination of reservoir regulation rules in light of uncertain estimates of river flow in the Han River Basin, Republic of Korea, shows that two strategies will improve total hydroelectric...
