Partnership in Environmental Design for Brush Creek Flood Control
Brush Creek drains a highly urbanized area in metropolitan Kansas City. A large physical model was used to develop a channel modification design for flood control. The Parks and Recreation...

Redundancy and Reliability of Water Distribution Networks: An Entropy Based Approach
Based on the concepts of entropy and graph theory, a functional form is developed as a quantitative measure for redundancy in water distribution networks. This function was obtained by...

Physical Modeling of Heated Discharges into a Stagnant River
An alternative cooling system study was performed for the Damietta Combined Cycle Plant in Egypt. The alternatives included spray canals, helper cooling tower and once-through cooling....

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...

Physical Modeling of Major Cutoffs
In 1987, a model study of Lock and Dam No.4 on the Red River in Louisiana required two major cutoffs and a lock and dam to be modeled. Although the Waterways Experiment Station has modeled...

Flow Characteristics in an Irregular Spillway Model
A physical model of the spillway for a proposed water supply reservoir near Meridian, Texas, was constructed to determine the optimum spillway design which would maintain an acceptable...

Bonneville I Powerhouse Station Service Unit Rehabilitation
This paper presents the work being done towards the rehabilitation of the Bonneville I station service unit. The rehabilitation of this unit includes a generator rewind, excitation system...

Retrofitting of Hydro Electric Generators with Bus Fed Solid State Excitation Systems
The Northern Hydro Division has completed retrofitting the excitation systems on 22 generating units ranging in output from 1 to 95 MWatts. The Big Creek Hydro Project upgraded these systems...

Understanding Generator Static Excitation System
This paper explains some of the basic terms and features associated with a static excitation system (SES) to enable non-specialists to specify it according to their requirements. A simple...

Sediment Transport Modeling
This is the Proceedings of the International Symposium on Sediment Transport Modeling, held in New Orleans, Louisiana, August, 1989. It reviews the state of the art and presents the latest...

Applications of Computer Graphics in Construction
Stone & Webster Engineering Corporation has implemented an integrated computer system for engineering, design, construction planning, and project management based on a relational...

The Role of Model Studies in Add-On Hydro Projects
The reasons for modeling add-on projects are reviewed, and guidance given for the process of determining, first, the need for modeling, and second, if modeling is necessary, whether physical...

Characteristics of Nonstationary Response of Linear Systems
A new formulation for the statistics of the response of linear systems to nonstationary excitation is developed. Both the process and its envelope are examined and exact statistics are...

One Solution for Different Stochastic Systems
It is shown that different dynamic systems under different sets of random excitations can share an identical probabilistic solution. Such systems are said to be stochastically equivalent,...

A Probabilistic Comparative Study of Various Base Isolation Systems?Nonstationary Earthquake Excitation
A probabilistic comparative study of various base isolation systems is carried out. The laminated rubber bearing with and without lead plug, the resilient-friction, and the EDF base isolation...

The Design and Construction of a Mass Armoured Breakwater at Hay Point, Australia
The design and construction of a prototype mass armored breakwater is briefly described. The paper also explores the practicality of allowing the progressive interaction of design, physical...

Physical River Model Results and Prototype Response
The Hydraulics Laboratory of the US Army Engineer Waterways Experiment Station (WES) has performed physical hydraulic model studies on various rivers for nearly 60 years. These studies...

Modeling of a Low Head Hydroelectric Project
In order to shorten the time to develop a hydroelectric project at the Corps of Engineers Hannibal Lock and Dam on the Ohio River for the City of New Martinsville, West Virginia, a turnkey...

Model-Prototype Correlation of Hydraulic Structures
Forty-three papers are contained in these proceedings, from the International Symposium on Model-Prototype Correlation of Hydraulic Structures. The papers cover a broad range of subjects...

Design of Breakwaters for Hurricane Wave Attack
The breakwaters protecting Port of Haina in the Dominican Republic have been repeatedly damaged by hurricane storm waves. Attempt to repair the destroyed portions have been largely unsuccessful....
