Measured Performance and Numerical Analysis of Buried Pipe
This study shows that the behavior of a soil pipe system can be assessed by a nonlinear elasto-plastic finite element analysis. The results of numerical calculations are compared to the...

Design of Drainage Pipes Below Landfills
Drainage pipes are an essential component of landfills. Even though their embedment conditions differ substantially from those of pipes for municipal utilities near the ground surface,...

FE Elastic Analysis of Measured Earth Pressure on Buried Rigid Pipes in Centrifuged Models
FE elastic analyses of earth pressure on buried rigid pipes yielded results that agreed well with the earth pressure measured in 42 centrifuged models, confirming both the reliability...

The Effect of Compaction on Buried Flexible Pipes
This contribution presents an analysis of the installation of flexible pipes in granular soil. The deformation of the pipe cross section is measured in field and laboratory tests. It is...

Designing Vitrified Clay Pipe Systems with EASE
NCPI has developed a computerized trench load design program which provides a broad and complete spectrum of design options which will enable engineers and contractors to safely design...

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...

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...

Diffusion Coefficients and Hydraulic Conductivity in Unsaturated Hanford Soils and Sediments
Two groundwater transport parameters of some Hanford formation materials, the hydraulic conductivity and the diffusion coefficient, were measured to aid in predicting contaminant migration....

Reconnaissance ? ??C and ??⁸O Data from Trench 14, Busted Butte, and Drill Hole G-4, Yucca Mountain, Nevada Test Site
Trench 14 was excavated to investigate the extent of Quaternary movement on the Bow Ridge fault, a north-south structure on the east side of Yucca Mountain. The trench exposes calcite...

Lunar Base Elements Designed for Robotic Operations
Equipment concepts developed for a study of robotic lunar surface operations are presented. The concepts were evolved together with a consistent robotic buildup and operations scenario;...

Composting for Lunar Agriculture
Alternative technologies for the microbially mediated biological oxidative transformation (composting) of human wastes and other organic wastes are presented. Batch mode and continuous...

Wastewater Balance for Storage Pond at Land Treatment Site
Land application is an established method for treating municipal wastewater in the United States. Most land application operations include on-site facilities to store wastewater during...

Nonpoint Source Pollution Control & Land Use
Nonpoint source pollution control requires dealing with city, suburban and rural activities, and controlling pollution either at source, by detention basin quality control or by treatment...

Morris Sheppard Dam: A Rational Approach to Stability Analysis
This paper details the excessive foundation piezometric conditions found during a routine five-year inspection, and presents the results of backfigured stability analysis of a critical...

Benefit/Cost Analysis of Stormwater Detention Systems
In the past, detention basins have been designed to control peak discharge rates. However, there is considerable interest in using the detention basin for control of nonpoint source pollution....

Evaluation of Global Warming Impact on Soil Moisture and Water Runoff in Texas
In this paper a numerical evaluation of the variability of soil moisture and surface runoff due to global warming is carried out. An analytical model of the soil moisture balance based...

Groundwater Contamination from an Unlined, Poorly Capped Landfill
This paper presents a case study of groundwater and surface water contamination from a major, unlined, and poorly capped municipal landfill located in Western Washington. The landfill...

Contributions of Satellite Imagery to Water Resource Evaluations
Satellite images may also facilitate the development and maintenance of regional Geographic Information Systems (GIS) by providing both a source of base map creation and update, as well...

Comparison Between the Field and Laboratory Measured Properties of a Clay Liner
Hydraulic conductivity (K) and bulk density (BD) of an experimental clay linear were evaluated at a large number of locations using standard methods. They were then compared to laboratory...

Measuring Performance of Clay Containment Barriers
Clayey soils compacted to engineering specifications are widely used as structures for hydraulic containment. Current applications include landfill liners, landfill covers, pond liners,...
