Wave Forecasting for Construction in Mobile Bay
Wave heights were forecast for day-to-day pipeline construction operations in the Main Pass area of Mobile Bay. A low-cost forecasting procedure was developed using the wave generation...
Tackling Trapped Sediments
Crater-sink fluidization has been used to recover sediment from harbors for the past couple of decades. Can this method bypass sediment around dams and return it to eroded beaches, solving...
Influence of Gas Phase Turbulence on the Transport of Particles
An interesting and perhaps unexpected flow feature characterizing the transport of a gas-solid suspension in a vertical duct is the radial nonuniformity of particles over the tube cross-section....
Hydrogen Reduction of Lunar Soil and Simulants
Carbotek, Inc., and the Energy and Environmental Research Center (EERC) are cooperating on further development of the Carbotek process to produce oxygen from lunar ilmenite by hydrogen...
Lunar Oxygen ? The Reduction of Glass by Hydrogen
The direct reduction of volcanic glass by hydrogen has been proposed as a method of extracting oxygen from the lunar soil. Experiments using lunar simulant glasses reacted with flowing...
A Modified Sulfate Process to Lunar Oxygen
A modified sulfate process which produces oxygen from iron oxide-bearing minerals in lunar soil is under development. Reaction rates of ilmenite in varying strength sulfuric acid have...
Steady State Composition with Low Fe?+ Concentrations for Efficient O2 Production by Magma Electrolysis of Lunar Soils
Parameters are estimated for a hypothetical, well stirred, continuous-feed electrolytic cell that converts 20% of a lunar soil feedstock to O2 gas,...
Better Cover-Ups
Designing the final cover for a solid waste landfill or remediation site is often trickier than designing its lining because a cover will undergo more unpredictable stress and distress...
Design of Irrigation Distribution System
This paper briefly discusses the Bureau of Reclamation's process of developing the rehabilitation of the Grand Valley Unit in Colorado. Sections are included on accessing needs of the...
Applying the ARMOS and MOFAT Models to a Major Oil Spill
A study was undertaken to evaluate the impact of a crude oil pipeline rupture in the recharge area of the aquifer serving most of West Tennessee. The main challenge was to model the volume...
Building a Pipeline?Not a Flow Through Process
This paper will illustrate that the planning, design, and construction of a 32-mile water supply pipeline from Stockton Lake to Springfield involves more than just digging a trench, placing...
Case Studies of Utilizing a Flexible Automated Supply in Developing Countries
The need is seldom questioned for a water supply that is available when the crop needs it - frequency; at a rate that can be satisfactorily used; and for a duration that provides just...
The Total System Solution
Most pipeline reconstruction programs carried out to date have been crisis driven or reactive instead of system wide approaches to problem solving. Two tools have been devised to change...
Planning, Assessing and Implementing Pipeline Rehabilitation Options
The methods of investigation for determining pipeline rehabilitation options for design and construction are directed chiefly toward: a) cost minimization of necessary rehabilitation projects;...
Design Criteria and Specifications for Pipeline Rehabilitation Projects
Pipeline rehabilitation, while not a completely new technology, is nevertheless a fairly recent development, just now coming to the forefront as to common usage. It is not however a fail-safe...
Development of a Water Conservation Program for the Spring Valley Water Company
The Spring Valley Water Company, an investor-owned water utility serving over 58,000 customers in Rockland County, New York, has developed a water conservation program that is sensitive...
Water Main Rehabilitation Needs for the 1990's
Distribution systems represent the major portion of water utilities capital assets. There are growing concerns about water quality deterioration within distribution systems, and hydraulic...
A Review of Current UK Techniques for Rehabilitating Water Mains
This paper describes the main techniques used in the UK Water Industry to rehabilitate water mains, highlighting their advantages and disadvantages....
Cost of Rehabilitation of Water Distribution Systems
The Chester Water Authority was established in 1868 and supplies water to residential and industrial customers in three counties in Southeastern Pennsylvania, and in addition, wholesales...
Water Main Rehabilitation Using Silicote Lining
In an attempt to find a cost effective rehabilitation alternative for over 320 miles of unlined distribution water main, the Louisville Water Company has evaluated a new rehabilitation...
