Pyrites Hydroelectric Project, Canton, New York
This paper describes the Pyrites Hydroelectric Project in Canton, New York, an 8-MW project completed in December 1985. The key to its successful development was a team approach that included...

Sinkhole Rectification by Compaction Grouting
The unraveling of the overburden by solution activity in karst formations has caused many problems in existing structures and has generated high foundation costs on new construction. Slurry...

Probabilistic Load Combinations in Nuclear Structures
A variety of loads affect a nuclear power facility during its lifetime. The magnitudes or intensities of these loads are uncertain, and for some of them, their time of occurrence is also...

Stochastic Properties of Wind Spectra
In the first part of this paper the correlation function of measured wind spectra is compared with theoretical correlation models assuming a stationary wind process. This comparison indicates...

Bayesian Updating of Seismic Fragilities of Nuclear Power Plant Components
Seismic fragility is represented by a curve of the conditiional probability of failure as a function of the peak ground acceleration. Since there are many uncertainties in the model and...

Revising a Reservoir Rule Curve for Multiple Uses
The Jackson Hydroelectric Project generates power, supplies municipal water, provides flood control, maintains anadromous fishery minimum instream flows and studies various reservoir rule...

Risk Management for Water Supplies During Droughts
This paper describes a method for deriving policies for the operation of public water supplies under impending and actual drought conditions. Unlike previous models based on optimization...

An Analysis of Hourly Water Use in Austin, Texas
While it is possible to calculate water use over a fairly short period of time, this only yields a single value for peak use. It does not give a comprehensive understanding of the frequency,...

IWR-Main?Version 5.1?An IBM-PC or Compatible Water Use Forecasting System
The IWR-MAIN water use forecasting system is a sophisticated and flexible computer program designed for estimating and forecasting municipal water requirements. The IWR-MAIN system is...

Instituting Increasing Block Rate Pricing as a Water Conservation Measure
The objective of this paper is to demonstrate the benefits of an increasing block rate pricing policy as a water conservation measure. By changing the pricing structure, demands will change...

Water Demand Forecasting in Southern California
A study of annual water use in Southern California is made in order to determine the cause of unusually high demands in 1987. Regression analysis of the demands and analysis of ratios...

Water Demand Forecast Uncertainty
This paper examines the effect of water demand forecast uncertainty on the operation of a city's water supply system. It is based on a number of years experience the author...

Alternating Direction Oxidation Ditches?A Cost Saving Technology from Denmark
A soon to be released EPA report claims that in Denmark, small alternating direction oxidation ditches (ADOD) save as much as 70% of the cost for conventional oxidation ditches. The alternating...

Reef Breakwater Response to Wave Attack
A method of predicting stability of a class of low-crested rubble mounds referred to as reef breakwaters is presented. Findings are based on a study which included an extensive series...

Water Power '87
The 1980's have been characterized as an era of uncertainty for world energy including future demand for energy, fuel prices and availability, regulatory constraints, environmental...

A Study in Nuclear Decommissioning
The Gentilly-1 nuclear power plant two year decommissioning project launched a series of firsts for the nuclear power industry. It was the first commercial sized plant in the world to...

Corrosion Monitoring of Critical Service Pipelines
Corrosion, including microbiologically influenced corrosion (MIC), is receiving much attention as a significant piping material performance concern particularly for critical service pipelines...

Design for Variable Frequency Drive Applications
This paper presents fundamental design criteria used to evaluate the operational and economic feasibility of installing a variable frequency drive (VFD) on a petroleum products pipeline....

Lightning Spurs Hydro Rehab
In 1986, a bolt of lightning hit the Upriver Hydro Project in Spokane, Washington and tripped the plant off line. The event triggered a series of events that included an undermining of...

Energy/Environment Opportunities for Civil Engineers
In the West, Nuclear Facilities Decommissioning; In the East, Implementation of Waste to Energy Systems
The papers in this book examine and provide illustrations for civil engineering opportunities in resolving apparent conflicts between needs for energy generation and environmental acceptability....
