UV Disinfection of Wastewater: A Pilot-Scale Study of Performance
A pilot-scale study of UV disinfection under field conditions was conducted. Inactivation and photoreactivation was well correlated with UV dose. Standards of 100 coliform/100 mL were...
An Integrated Study of Air Toxics Emissions from an MSW Landfill
An integrated approach was used for a study of air toxics emissions at a municipal solid waste (MSW) landfill (LF) consisting of field sampling, emission estimation, atmospheric dispersion...
Evaluation of
This paper examines the potential application of in-situ bio-dentrification as well as pertinent physical and biochemical factors that control the process to reduce nitrate in groundwater...
Using Multiple Water Quality Models for Determining Variable Emission Levels for Wasteload Allocation
We present a methodology for determining the least-cost wasteload allocations from multiple point sources discharging into a single water body. The system of point sources is modeled as...
Numerous releases of hazardous substances have occurred at uncontrolled sites all around the United States. These sites pose toxic threats to public health and our environment, and potential...
Electronic Computation

CADD for Export
By using sophisticated structural design software and high-speed PCs, engineers in Pittsburgh overcame myriad problems when designing a highrise industrial tower in India. First, they...
Evaluating the Dynamic Operating Benefits of Hydro Power Plants
In 1986, the Electric Power Research Institute asked Decision Focus to develop a new planning model to quantify the dynamic operating benefits of power technologies that offer operating...
Fish Protection at Water Intakes Using a New Signal Development Process and Sound System
American Electric Power Company, Inc., is exploring the feasibility of using a patented signal development process and sound system to guide aquatic animals with underwater sound. Sounds...
Hydraulic Model Studies for Non-Federal Projects at Federal Dams?A Case Study
This paper will discuss the hydraulic model studies for hydropower projects developed by Arkansas Electric Cooperative Corporation (a non-federal entity) at existing Corps of Engineers...
Varying Generator Excitation to Control Draft Tube Surge
The Bureau of Reclamation recently experimented with varying the excitation applied to a hydroelectric generator to control power swings caused by draft tube surging in a Francis turbine....

Beech Dam is part of the Beech River watershed resource development located in Decatur and Henderson counties in west Tennessee. The development consists of eight dams and approximately...
Foundation Investigations of Concrete Dams
This paper discusses a series of foundation investigations conducted on concrete dams by Pacific Gas and Electric Company. The paper focuses on investigative techniques, equipment, appropriate...
Rocky Mountain Project Power Tunnel Filling Test
The Rocky Mountain Project, a pumped storage development located in NW Georgia, is owned jointly by Oglethorpe Power Corporation and Georgia Power Company. Initial construction included...
Operation of Hydropower Plants Considering Daily Streamflows
Operation of hydropower plants is a sequential decision process often modeled as a dynamic programming problem. Typically, such formulations consider monthly stages assuming that monthly...
Seismic Analysis of the Bonneville 1st Powerhouse
The Bonneville 1st powerhouse monoliths were constructed during the period of 1938 to 1942 and were designed against seismic loads using the old lateral coefficient method. The Corps of...
Concrete Gravity Dam Cracking Analysis Methodology
This paper describes a methodology for the prediction and evaluation of cracking behavior in concrete gravity dam's for use in periodic safety investigations as outlined in...
Uplift Reduction Using Drains
Uplift in cracks and in rock-concrete interface plays a crucial role in dam stability. Drains can be designed to intersect these cracks to reduce uplift. This paper explains how the effectiveness...
Cone Penetration Testing: Cost Effective Soil Exploration
On reviewing the 1987 Part 12 Dam Safety Inspection Reports for the Wisconsin River Power Company's Petenwell and Castle Rock Dams, the Federal Energy Regulatory Commission...
Field Tests of a Lewiston Pump-Generating Unit
An extensive field test program was undertaken on a Lewiston Pump-Generating Plant (LPGP) unit at the Niagara Power Project, owned and operated by the New York Power Authority. The objective...
