Seismic Design of RC Structural Walls with Unsymmetrical Cross-Sections
An overview of seismic design issues and current experimental research for walls with unsymmetrical cross-sections is presented. The experimental studies include approximately 1/4 and...
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...
Methods for Risk and Reliability Analysis
Recently, there has been considerable emphasis on the state of decay in the nation's infrastructure because of its importance to society's needs and industrial growth. Water distribution...
Water Infrastructure Risk Ranking and Filtering Method
The availability of water distribution infrastructure is critical to the sustained support and growth of society. Water infrastructure consists of systems that carry water (pipe and irrigation...
Modeling Issues of Copper Solubility in Drinking Water
The paper discusses the application of a model to the solubility of copper in drinking water. This paper is the result of numerous forms of pitting corrosion and pipe failures. Monitoring...
Transport Process of Surface Liquid Spills
A mathematical model simulating the scenarios of surface liquid spills is presented in this paper. This model describes the advance front and recession curves of surface spills based on...
Pipe Utility Evaluations With the Aid of GIS
Geographical Information Systems (GIS) are starting to be used on a day to day basis to solve community problems and optimize the use of their valuable resources. One engineering application...
Velocity Control Rings for RC Pipe on Steep Slopes
This paper discusses the use of internal concrete rings to reduce velocity and concrete erosion for reinforced concrete pipes on steep slopes in the Southern California area....
The Rest of the Best
Nominations for this year's Outstanding Civil Engineering Achievement Award ranged from a channel built to control flood waters to the construction of a wastewater pollution...
Northridge: Questioning Our Codes
The earthquake that struck Southern California at 4:31 A.M. Pacific Time on January 17, 1994 was responsible for 61 deaths, more than 9,000 injuries and $30 million in damages. From its...

Upgrading Dubai's Sewers
The sewerage system serving the city of Dubai in the United Arab Emirates, is plagued with odor and corrosion problems. System elements were deteriorating and failure rates were increasing....
Building A Barrier Wall Through Boulders
Engineers and contractors conceived a novel approach to a barrier wall at a difficult site near the Niagara River in New York State. The site had been contaminated by a chemical company...
Protecting a Pipeline
A 30-inch oil pipeline, presently under construction through mountainous terrain in central Colombia, transports petroleum from the Cusiana oil field to the coast. The discovery of the...
Sludge Under Pressure
Few wastewater engineers ever have to deal with high-pressure pumping. In San Diego, however, city engineers will soon oversee a 100,000 ft long psi main that will transport sewage sludge...
The Use of Built-Up Compression Members?A Fabricator's Viewpoint
A variety of cross-sections of built-up compression members that have been used are shown. Suggested items that need to be addressed for the successful design and fabrication are discussed....
