Los Angeles' Pipeline Rehabilitation Program
One-third of the City of Los Angeles' 7,000 mile water distribution system had been installed without internal protection. The Water System is aiming for a 900,000 foot per...
Heuristic Optimization of Water Distribution Systems
A design heuristic for the optimization of water distribution systems is presented. Algorithm TREESEARCH finds a near optimal core tree layout. Algorithm REDUNDANCY adds redundant links...
Computer Modeling as a Tool for Selecting Appropriate Air Valves for Pipeline Surge Protection
Waterhammer in water or wastewater pipelines is caused by events such as a pump power failure and can have potentially damaging effects on the pipeline or pipeline hardware. In particular,...
Network Modeling in a Water System with Ferrous Deposits
This paper presents the experiences and results of a network modeling study. A model for the University of Idaho water supply system was developed and verified to the extent possible with...
A Comprehensive Algorithm for Network Calibration
An explicit calibration algorithm is proposed which provides the direct and rapid adjustment of the pipe roughness coefficients and junction node demands that exactly meet a specified...
A Water Information System for Decision Support in Design, Operation and Management of Distribution Systems
The design, operations and management of water supply and distribution systems require considerable amounts of data and data processing and analysis. What is not available to the water...
Rehabilitation of Water Distribution Systems Planning and Implementation
The paper describes the approach taken to develop infrastructure rehabilitation procedures for Water Distribution Systems. Early research attempted to develop a mains condition oriented...
Propagating Buckles in Deep-Water Pipelines
A procedure is presented for the analysis of propagating buckles in deep-water pipelines. Results pertaining to quasistatic and dynamic buckles are summarized and compared with available...
Pipeline Crossings
This proceedings of the Pipeline Crossings Conference, held on March 25-27, 1991 in Denver, Colorado, presents information on aspects of various pipeline crossings. It covers such broad...
Distant Eyes
A remotely operated vehicle is a miniature unmanned submersible that contains lights, a video camera, other instrumentation, and motor thrusters to move it through the water. The operator,...
Induced Subsidence: Environmental and Legal Implications
Subsidence of coastal areas can be induced by withdrawal of fluids from shallow, unconsolidated horizons beneath the shore zone. In southern California, Huntington Beach, Torrance/Redondo...
How Has the Joint Review Process Evolved?
The Joint Review Panel (JRP) process in California was established for offshore oil and gas-related coastal development projects to avoid duplication of effort among various permitting...
Oil-Spill Contingency Planning for OCS Operations
Oil-spill preparedness and response have been an important part of the Minerals Management Service (MMS) regulatory program since the Santa Barbara spill in 1969. The focus of the spill...
The Pacific Northwest OCS Task Force?Evolution and Status
The Pacific Northwest Outer Continental Shelf (OCS) Task Force was established in January of 1989 to provide advice to the Secretary of the Department of the Interior (DOI) on issues related...
Mitigation for Offshore Development/Fishing Conflicts
Three case studies, WestGold gold dredging offshore Nome, Alaska, Endicott Causeway off Alaska's North Slope, and Platform Irene offshore California, show that project related...
Onsite Compliance Programs for Major Oil and Gas Projects
Major oil and gas projects developed in Santa Barbara County are monitored for compliance with conditions of approval through various enforcement and compliance programs. the Resource...
Effective Mitigation of Air Emissions from OCS Sources
Unmitigated, platforms and associated facilities in the OCS typically emit large quantities of air pollution from power generation, drilling, transportation and other activities related...
Monitoring and Mitigating the Socioeconomic Impacts of Coastal Oil and Gas Development
Santa Barbara County has required that all companies engaged in major offshore oil and gas projects participate in a Socioeconomic Monitoring and Mitigation Program (SEMP). Yearly impact...
Chemical Composition, Physical Properties and Off-Site Migration of Municipal Landfill Gas
A sampling program of headspace gas from four monitoring wells and of off-site migration at three property line sites was conducted as part of a remedial design of a municipal landfill....
Sediment Removal from Sand Hills Aqua Farms Using a Sediment Evacuation Pipeline System
