Model for Water Quality in Periphery of Distribution Systems
A model is presented for water travel time and chlorine concentration in periphery dead ends of the water distribution system. The model is developed under the premise that residential...
Comprehensive Modelling of Water Distribution Networks
An analyst of a water distribution systems must frequently contend with a host of problems with very different time scales. Traditionally, such concerns have been accommodated by having...

The Cold Regions Infrastructure?An International Imperative for the 21st Century
This volume includes papers presented at the Eighth International Conference on Cold Regions Engineering?The Cold Regions Infrastructure: An International Imperative for the 21st Century....
Mapping History
Difficult, environmentally sensitive terrain combined with the fact that Canadian Western Natural Gas's new Banff pipeline will be laid in archaeologically rich ground posed a challenge...
Marine Borers Are Back
Cleaning up the nation's harbors has brought a resurgence in marine borer activity. These organisms, mainly the teredo and the limnoria, eat at timber piers, undermining critical...
On Target: The Arrowhead East and West Tunnels
Two new water tunnels in Southern California will feature continuous impermeable linings, extensive probing and grouting, and unique seismic sections to minimize damage in fault zones...
Lessons From Kobe
On Jan. 17, Kobe, Japan became the first post-World War II, heavily populated, industrialized area to bear the full brunt of a high-magnitude earthquake. Engineers hope the resulting destruction...
Trenchless in San Diego
The Middletown Trunk Sewer is located near downtown San Diego. Sewage backups prompted a study, recommending construction of a larger replacement pipeline. The City of San Diego prepared...
Advances in Underground Pipeline Engineering II
The first international conference on Advances in Underground Pipeline Engineering was held in 1985. Some 50 authors and over 300 delegates from 20 countries took part in the presentations...
Sounding Out Scour
As engineers are aware, detection of bridge scour is the best protection. A method for monitoring scour during low, normal or high water flows would also help alleviate some of the ambiguity...
Doubling A Pipeline
The 36 in. natural gas pipeline built 32 years ago by Pacific Gas and Electric (PG&E) its subsidiary Pacific Gas Transmission (PGT) from Canadian fields to central California has...
URSULA: Design of an Underwater Robot for Nuclear Reactor Vessel Inspection
This paper describes the development of an underwater robotic system that will be used to perform ultrasonic inspections of nuclear reactor vessel weldments. The development effort consists...
Steady-State Analysis of Buckle Propagation
A novel finite element technique for the analysis of buckle propagation in pipelines is presented. The propagation pressure, propagation profile, the state of stress, and deformation during...
The San Gorgonio Pass Water Project
To meet the growing water demand of its service area, the San Gorgonio Pass Water Agency has planned to import water from the State Water Project and distribute the water to retailers...
The Everett, Washington, Water Supply IRP
The City of Everett, Washington, supplies water to most of the population of Snohomish County, located just north of Seattle. The County is rapidly urbanizing, and preliminary review of...
Potable Water Reclamation?A Practical Option to Traditional Sources
This paper describes the development of potable water reclamation alternatives to meet the future municipal water needs of the City of Colorado Springs, Colorado. By the year 2042, the...
Determining Optimal Parameter Dimensions for Water Distribution Network Models
Water distribution systems contain a large number of pipes whose roughness factors are unknown prior to model calibration. During the calibration process, pipe roughnesses for each link...
A Case History of Settlement of an Embankment on Lagoonal Deposits Influenced by Artesian Conditions
A geotechnical engineering investigation was performed for the Pearl Kai Center, a shopping center in the Pearl Harbor area of the island of Oahu, Hawaii. The proposed commercial development...
