Short-Term Versus Long-Term Pipe Ring Stiffness in the Design of Buried Plastic Sewer Pipes
It is often discussed which pipe ring stiffness should be used when designing the long-term deflection of buried plastic sewer pipes; the short-term value or the long-term value? As the...
Column Separation in Pumped Pipelines
Pressure transients are common occurrences in water supply systems. Pipeline standards and design/testing techniques will normally provide sufficient protection for transmission and distribution...
Pipeline Leak Detection and Location
A real time pipeline leak detection and location system has been developed. This system consists of a numerical model for transient flow, two sets of pressure and flow measurement equipment,...
Whatever Happened to Long-Term Bridge Design?
The Chairman of the Board of one of the leading engineering firms in the nation ponders the future of American bridges. In today's designing of bridges, Thomas R. Kuesel points...
Seam Examination
Charron discusses the importance of seam sampling in geomenbrane installation. In 1988, about 30 million mi of polyethylene geomembranes were used to line landfills, liquid impoundments,...
Design of Ductile Iron Pipe on Supports
Design procedures for ductile iron pipe in normal underground service have been well established. The standard design considers hoop stresses in the pipe wall due to internal hydrostatic...
Design of Drainage Pipes Below Landfills
Drainage pipes are an essential component of landfills. Even though their embedment conditions differ substantially from those of pipes for municipal utilities near the ground surface,...
Designing Vitrified Clay Pipe Systems with EASE
NCPI has developed a computerized trench load design program which provides a broad and complete spectrum of design options which will enable engineers and contractors to safely design...
Optimal Design of Water Transmission Mains
Capital cost for constructing a water transmission main includes cost of the pipeline and its associated installation costs. Also included in the capital cost is the cost of a pump station....
A Look Back in Time to Verify Life Cycle Cost Analyses
The proper engineering design of any hydraulic structure requires consideration of different but interrelated fields of: 1) Planning, 2) Hydrology, 3) Hydraulics, 4) Structural, 5) Installation,...
Structural Safety and Reliability
This proceedings of the 5th International Conference on Structural Safety and Reliability (ICOSSAR '89) held on August 7-11, 1989 in San Francisco, California contains almost...
Creative Connections: Bridges as Art
Princeton University professor of civil engineering David P. Billington, at the invitation of civil engineering professors at Tokyo University, tours Japan and critiques several of the...

Preliminary Methodology for Design of Stable Drifts for the Yucca Mountain Project
The Yucca Mountain Project is investigating the feasibility of locating a high-level radioactive nuclear waste repository at Yucca Mountain, Nevada. The conceptual design of the repository...
Approach to Developing a Ground-Motion Design Basis for Facilities Important to Safety at Yucca Mountain
The DOE has proposed a methodology for developing a ground-motion design basis for prospective facilities at Yucca Mountain that are important to safety. The methdology utilizes a quasi-deterministic...
Estimating Earthquake Sizes in the Basin and Range Province, Western North America: Perspectives Gained from Historical Earthquakes
Thirty eight historical earthquake from the Basin and Range province were used to examine three aspects of earthquake size and behavior: 1) the maximum background earthquake, 2) earthquake...
Simulation of Reactive Chemical Transport in a Varying Thermal Field with Reaction-Flow Coupling
A computer program, THCVP, simulates coupling between advective/diffusive solute transport and chemical reactions, coupling of the reactions to heat transport, and feedback from precipitation/dissolution...
Simulation of Radionuclide Retardation at Yucca Mountain Using a Stochastic Mineralogical/Geochemical Model
This paper presents preliminary transport calculations for radionuclide movement at Yucca Mountain using preliminary data for retardation parameter distributions based on mineral distributions....
Optimal Route Selection for High Level Nuclear Waste Transport Based Upon Radiological Risk
