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....
Analysis of Alternative Pipe Materials for a Major Public Water Agency
A major southwestern public water agency has historically specified the exclusive use of prestressed concrete cylinder pipe (PCCP) for large diameter water transmission mains. Due to the...
Twin Pipeline Crossing of the Fraser River
A new creek water supply was developed for the communities of Mission and Matsqui, British Columbia, Canada, in the early eighties. Over 60 kilometres of 450 mm to 900 mm diameter ductile...
Evaluation and Selection Methodology for Determination of a Preferred Pipeline Alignment
The San Diego County Water Authority (SDCWA) had need to construct a regional 108 to 72 inch (2.7 to 1.8 meter) diameter pipeline through San Diego County to increase water supply to its...
Field Experiment on Behavior of Continuous Water Main with a Miter Bend
A field experiment was conducted to investigate behaviors of a buried continuous steel water main with a 90-degree miter bend subjected to internal pressure and ground settlement. Deformations...
America's Irrigation: Can It Last?
Although irrigated agriculture has made a substantial contribution to food production and the economy in the U.S., its future is now at a crossroads for a variety of reasons. Irrigation...
Keeping Lifelines Alive
There were no city water supplies to fight the fires in San Francisco after last year's earthquake. The fires were brought under control because of an historic auxiliary water...
Iodine Transport Through the Soil-Plant-Atmosphere Continuum
The environmental assessment of the geological disposal of Canadian nuclear fuel waste involves transport modelling of radionuclides through the biosphere. Iodine-129 is a major fission...
A Preliminary Model for Carbon-14 Transport in a Clay Buffer
A model has been developed to assess the effect of calcite dissolution and precipitation reactions on the transport of 14C through a saturated, calcite-containing...
Natural Radionuclides in Groundwater From J-13 Well at the Nevada Test Site
The concentrations of U-238 and Th-232 chain members are extremely low in J-13 water, suggesting that their concentrations in groundwaters are largely governed by sorption/desorption processes....
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...
One-Dimensional Radionuclide Transport Under Time-Varying Conditions
New analytical and numerical solutions are presented for one-dimensional radionuclide transport under time-varying fluid-flow conditions including radioactive decay. The analytical solution...
Radioactive Materials Packaging Standards and Regulations?Making Sense of it All
Numerous regulations and standards, both national and international, apply to the packaging and transportation of radioactive material. These are legal and technical prerequisites to practically...
The Transportation Operations System: A Description
A system engineering approach is being applied to organize and develop relations among the people, hardware, and software of the Transportation Operations System (TOS), which will be a...
Development of Transportation Operations Requirements: Operations Planning
Transport conditions at various utility sites vary dramatically in terms of characteristics at and near the site, requirements, administrative procedures, and other factors. Continuation...
U.S. Department of Energy Motor Carrier Evaluation Program
The U.S. Department of Energy-Headquarters (DOE-HQ), Transportation Management Division (TMD) has the overall responsibility to provide a well-managed transportation program for the safe,...
Development of Rail Access to the Yucca Mountain Site: Technical and Publc Issues
The Yucca Mountain site, located on the southwestern edge of the Nevada Test Site (NTS), is an undeveloped area under investigation as a potential site for high-level nuclear waste (HLW)...
Optimal Route Selection for High Level Nuclear Waste Transport Based Upon Radiological Risk
The purpose of this paper is to demonstrate route optimization based directly upon the minimization of radiological risk as computed from local conditions. An operational impact analysis...
Diffusion Barrier Transport Properties of Unsaturated Paintbrush Tuff Rubble Backfill
Diffusion coefficients (D) were experimentally determined in unsaturated tuff gravel to evaluated the effectiveness of tuff gravel and rubble as a diffusion barrier to ionic transport...
Optimizing Spent Fuel Cask Designs for Use in the Federal Waste Management System
The DOE will design and develop a new fleet of casks to transport spent fuel using innovative approaches to optimize the cask design. Preliminary casks designs indicate capacity increases...
