Meeting Environmental Commitments at Power Plants Using Real-Time Reservoir Scheduling
This paper describes two different real-time modeling systems that determine if scheduled hydro releases will affect meeting environmental commitments. The modeling system for John Sevier...

Biological Methods Petroleum Hydrocarbons Cleanup
Cleanup of the ground water and soils from hydrocarbon spills has mainly focused on air stripping and activated carbon for ground-water treatment, and vapor extraction and excavation followed...

Settling Basin Model for the Personal Computer
The SETSIZE program, models sediment deposition in a settling basin. The program can be applied to determine the length of time until dredging or cleaning is necessary or solve for an...

Calibration of a Movable Bed River Model
This paper discusses the calibration procedures used for a model study of three miles (5km) of the Arkansas River. A hydro-power station will be added to an existing Corps of Engineers...

Electricity From Air
After a decade of research and dozens of feasibility studies at sites around the country, the first Compressed Air Energy Storage (CAES) plant in the U.S. is under construction at McIntosh,...

Power Without Acid
Anticipating tighter acid rain controls, DOE is developing duct injection units that can be attached to existing powerplants. In a typical duct injection system, lime is sprayed into existing...

Routing a Cold Water Release Through TVA Reservoirs to Control Intake Temperatures at a Power Plant
A volume of cold water was routed some 160 miles through the TVA reservoir system to keep a nuclear plant intake temperature within safety limits. Mathematical modeling of the operation...

Analysis of Pumping Station and Force Main Networks
A computer program to simulate the performance of wastewater pumping station and force main networks is discussed. Results are presented which compare system performance for steady and...

Design and Operation of Guard Gates
Guard gates for hydroelectric intakes and low-level outlets are normally intended for operation only under balanced heads. In the case of failure of regulating gates, the guard gate may...

Climate Change and U.S. Water Resources: Results from a Study by the American Association for Advancement of Science
The time horizon of the changes that might occur is similar to the time required for planning, approval, funding, construction and economic life of such major water facilities as dams,...

Jet Injection Model Studies for the City of Los Angeles
The Hypersion Treatment Plant for the City of Los Angeles is currently undergoing an expansion project. A major component of this system is a sludge recycling system. And it is essential...

Underwater Tunnel Inspection by Virginia Power Using a Submersible Robot
The Bath County Pumped Storage Station, has three large tunnels linking the upper and lower reservoirs. The 'Hydrover' submersible remotely operated vehicle (ROV)...

Far-Field Numerical Model Studies for Boston's New Secondary Treatment Plant Outfall Siting
By the late 1900s, Boston is scheduled to have built a new secondary treatment plant that combines the waste streams from two existing plant, and discharges the resulting liquid effluent...

Hydraulic Design Aspects of the Boston Outfall
The diffuser outfall under design for Boston must have the ability to be purged of seawater upon commissioning or following an accidental flow stoppage. The criteria governing the flushing...

Debris Torrents in Nepal and Use of Reliability Engineering Concepts During Redesign of River Works
Debris torrents, generated by cloudbursts and by glacier lake outbursts, occur frequently in the Nepal Himalaya. A simple fault tree analysis is applied to the destruction of a diversion...

Siting the New Boston Outfall: Near-Field Considerations
This paper describes a procedure applied in near-field considerations for siting the new outfall to serve the Massachusetts Water Resources Authority's (MWRA) proposed regional...

The Hydro Business: 1990 and Beyond
During the last ten years, hydroelectric generation received more and more attention as a source of reliable and economical electricity. Since the first WATERPOWER conference, the industry...

Status of Hydropower Development at Corps of Engineers Dams
The Corps of Engineers is the largest single supplier of hydroelectric power in the United States with 74 projects and an installed capacity of 20,839 MW. In addition, 33 Corps projects...

The Development and Writing of the ASCE/EPRI Hydroelectric Guidelines
In the Spring of 1989, the American Society of Civil Engineers (ASCE) and the Electric Power Research Institute (EPRI) jointly published their Civil Engineering Guidelines for Planning...

Project Evaluation?Don't Miss the Boat
The hydroelectric developer is faced with many decisions during the evaluation stage. These include determining the size of the project, financial analysis to be used, type and number...
