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...
Carbon Isotopic Data from Test Hole USW UZ-1, Yucca Mountain, Nevada
Rock-CO2-gas analyses in test hole USW UZ-1 at Yucca Mountain indicate that gas movement in the unsaturated zone is likely through a dry-fracture...
The Role of Fault Zone in Affecting Multiphase Flow at Yucca Mountain
Within Yucca Mountain, the potential High Level Nuclear-Waste Repository site, there are large scale fault zones, most notably the Ghost Dance Fault. The effect of such high-permeability,...
Flow Visualization and Relative Permeability Measurements in Rough-Walled Fractures
Two-phase (gas-liquid) flow experiments were done in a natural rock fracture and transparent replicas of natural fractures. Liquid was injected at constant volume flow rate, and gas was...
Global Approaches for the Nonconvex Optimization of Pipe Networks
Because the pipe network problem is nonconvex, two global search schemes, MULTISTART and ANNEALING, are employed to permit a local optimum seeking method to migrate among various local...
Pipe Network Optimisation Using Genetic Algorithms
A new optimization technique of generic algorithms has recently been successfully applied to pipe network optimization. In this paper a parametric analysis is carried out of the genetic...
Alternative Designs for Permanent Protection of the San Luis Rey River Aqueduct Crossings
The San Diego County water Authority was organized to provide an imported supply of water to the San Diego region. The sole source of the water to the Authority is Metropolitan Water District...
Optimal Rehabilitation Model for Water Distribution Systems
The objective of this paper is to describe a new methodology which can select the pipes to be rehabilitated and/or replaced in an existing water distribution system and determine how much...
Non Contact, Remote Sensing of Buried Water Pipeline Leaks Using Infrared Thermography
Subsurface water pipelines, sewer and buried utilities throughout America and the rest of the world range in age from hundreds of years old to brand new. They all have, however, one fact...
Global Distribution of Water Through the Oceans
The paper is a conceptual investigation of a pipeline and bladder system for conveying and storing fresh water in the oceans. Modeling is recommended to provide background on what could...
Water Pipelines: Tackling Toxics
In the spring of 1988, residents of Girwood, Alaska contacted the state's environmental agency to complain of foul-tasting drinking water. While most complaints came after...
High-Tech Landfill Caps
Just as federal and state regulations detail every aspect of landfill location, construction and operation, they now detail every aspect of its design closure. A typical municipal solid...
The Role of Information for Offshore Natural Gas
Natural gas may play a larger role in the Nation's energy mix. Extensive reservoirs of natural gas exist on the Outer Continental Shelf (OCS). But exploration for oil and gas on the OCS...
The Value of the Federal Oil/Gas OCS and Its Required Nexus with the Changing Perceived Quality of Rights
A particular few of thousands of hardly distinguishable and certainly previously undistinguished Federal OCS oil/gas tracts can suddenly become prizes of great value. Vice versa, prized...
Environmental Compliance and Offshore Oil and Gas Exploration and Production
The economic impacts of multiple environmental regulations of offshore oil and gas exploration and production are examined using an integrated, investment-production-regulatory model developed...
The Whole Picture: Federal Statutory and Regulatory Authorities Which Govern Oil and Gas Activities on the Alaskan Outer Continental Shelf
Oil and gas activities conducted on the Alaska Outer Continental Shelf (OCS) are subject to multiple Federal laws which result in safe operations and environmental protection. Lessees...
Environmental Compliance Monitoring Program for Offshore Oil and Gas Exploration and Development and Production Activities in the Pacific OCS Region
The Pacific Outer Continental Shelf Region of Minerals Management Service has recently development and is implementing an Environmental Compliance Monitoring Program. Each of the 24 oil...
