A Wetlands Sewage Treatment System for the Community of Teslin
The Village of Teslin, with a population of 450, is located in south-central Yukon, approximately 180 km southeast of Whitehorse. Since 1977, the community has been trucking its sewage...
PS 5 Sewage Lagoon Embankment Stabilization
In 1981 an embankment containing a three-cell wastewater treatment lagoon was constructed adjacent to the northern edge of the Pump Station 5 gravel pad on the Trans Alaska Pipeline System....
Freeze-Thaw Effects on Clay Covers and Liners
The properties of clay covers and liners used for containing solid waste materials are highly susceptible to environmental stresses. Even when clay layers are protected from drying, freezing...
Experimental Study of Adfreeze Heaving of Augered Caisson Footings
In order to establish the required depth of augered caisson-type footings in cold regions and their optimal design against adfreeze heaving, an experimental field investigation has been...
The Thermal Regime Surrounding a Longitudinal Edge Drain
Newton Airfield in Jackman, Maine, was constructed in 1986 to perform as a drained pavement system. The drainage design consisted of a permeable base course with a longitudinal edge drain...
Numerical Analysis of Frost Shields
The term 'frost sheilding' has been used to describe the practice of using flat stock rigid insulation materials burial above a water or sewer pipe to reduce...
Computer Predictions of Thaw Beneath Gravel Embankments on Warm Permafrost
A computer model was used to simulate the freeze-thaw effects of gravel embankments on warm permafrost typical of south-central Alaska using a one-dimensional finite-difference code, FREZ1D....
Treatment of Unstable Foundation Areas in Alaska's Pavement Management System
In the State of Alaska Department of Transportation and Public Facilities Pavement Management System (PMS) unstable foundation areas are defined as sections of roadway that experience...
Analysis of Soil-Stress Cell Interaction
Static loading experiments conducted on a soil stress cell embedded in a sand are presented. Stress cell performance was evaluated by comparing the indicated stress against the expected...
Earth Walls: Making the Right Choice
Earth walls are retaining walls where the ground assumes a load-bearing role. These walls either support compacted earth (embankment-type reinforced compacted earth walls such as Doublewal...
Effects of Natural Gas Storage on Gas Price Forecasts
This paper explores the effects of natural gas storage on short-term gas price forecasts. At the Southern California Edison Company (Edison), the gas price forecast incorporates a multitude...
The Future of Non-Utility Generation
The business of designing, constructing and operating non-utility owned electric power plants continues to evolve into the 1990s. The industry is consolidating as smaller market participants...
Cold Regions Engineering
This proceedings consists of papers presented at the Cold Regions Engineering Specialty Conference held in West Lebanon, New Hampshire from February 26-28, 1991. The papers cover nine...
Dallas' Flood Caverns
Dallas' North Central Expressway floods during heavy rains, but the dense development that helps create excessive runoff also precludes large detention ponds. The high-quality,...
Strain Distribution in Fault Zones and Fluid Flow
Field and laboratory studies have shown that mechanical shearing in fault zones produces a repeatable fabric that changes with increasing shear strain. In the brittle field of mechanical...
Computer-Assisted Geometric and Kinematic Analysis of Subsurface Faulting in the Vicinity of Yucca Mountain, Nevada, Using Balanced Geologic Cross Sections
Computer-assisted geological cross section balancing methods are used in the geometric and kinematic analysis of subsurface structures in the vicinity of Yucca Mountain, Nevada, including...
Microwave Measurements of the Water Content of Bentonite
The theory of operation of microwave coaxial resonators is described. Sample preparation and the application of resonator techniques to the measurement of the permittivity (dielectric...
Exclusion of Foreign Materials from the Savannah River Site (SRS) Canistered Waste Forms: Characterization of the Gas within the Free Volume
Glass-filled canisters, produced at the SRS Defense Waste Processing facility, must meet the Waste Acceptance Preliminary Specifications (WAPS) developed by DOE's Office of...
Effect of a Low-Permeability Layer on Calculated Gas Flow at Yucca Mountain
Yucca Mountain is being studied to determine its suitability as a location for a high-level nuclear waste repository. The mountain is a steep-sided linear ridge which is underlain by a...
Status of WIPP Compliance with EPA 40 CFR 191, December 1990?SAND90-2424C
Sandia National Laboratories is conducting performance assessments for the United States Department of Energy to use in evaluating compliance of the Waste Isolation Pilot Plant with EPA...
