Grade Control Structures for Pipeline Crossings in the Arid Southwest
Pipeline crossings at streams, rivers, and washes are at risk due to bed and bank erosion in the river environment. Buried pipelines may be exposed in the channel bottom by scour of bed...
Optimization of Soil Vapor Extraction System Design
Soil vapor extraction is a cost-effective technique for the removal of volatile organic compounds (VOCs) immobilized in the unsaturated zone. The design of a soil vapor extraction system...
Application of Regime Theory in Practice: A Case Study
Alluvial channels are known to adjust their slope, width, depth and velocity to achieve stable conditions given a supply of water and sediment. Scientific investigations of stable channels...
Experiences in Cleaning Up the Influence of Oil Spill on the Water Bodies
Experiences in cleaning up the influence of oil spill on water bodies of Komi Republic (European part of Russian North) and Dagestan Republic (North Caucasus) was generalized. In both...
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...
Cleaning Up Clay
Using soil vapor extraction to remove volatile organic compounds from ground water and unsaturated soils can achieve faster and more-complete cleanups than conventional pump-and-treat...

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...
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...
Seismic Design Guide for Natural Gas Distributors
This monograph presents an overview of the sources and geographical distribution of earthquakes, identifies earthquake hazards, and gives the implications of these hazards to gas distribution...
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...
Lunar ISRU: An Evolutionary Approach
The goal of this paper is to provide the reader with a vision of the individual steps required to bring ISRU from the current technological readiness level of lab experimentation, to large...
Lunar Oxygen Production - A Maturing Technology
Research on oxygen production from lunar rock and soil has made significant progress in the past two years. An extensive series of experiments on natural and synthetic analogs has concentrated...
Oxygen Generation from Synthetic Moon Soil Using a Plasma Reactor
A series of experiments were performed to evaluate the potential for generating oxygen from silica powder, alumina powder and a synthetic moon soil powder. A non-transferred arc plasma...
