Diffusion of Carbon Dioxide and Iodine Through Yucca Mountain Tuffs—Effects of Temperature and Moisture Content

A Markov Chain Approach for Analyzing Palmer Drought Index
Drought is conceived as a period of below normal precipitation or moisture deficiency that would affect the social and economic activities of a region. The Palmer Drought Index (PDI) is...

Effects of Soil Moisture and Physical-Chemical Properties of Organic Pollutants on Vapor-Phase Transport in the Vadose Zone

The SHRP-LTPP Asphalt Resilient Modulus Pilot Study
A SHRP asphalt concrete resilient modulus pilot study was initiated to provide important supplemental information related to the AC Mr program. Initially,...

Preliminary Calculations of Release Rates from Spent Fuel in a Tuff Repository
Time-dependent release rates of Tc-99, I-129, Cs-135, and Np-237 have been calculated for wet-drip and moist-continuous release modes from the engineered barrier system of a potential...

Moisture Diffusion in Concrete and Mechanisms of Drying Creep
The Pickett effect is the excess of creep at drying over the sum of shrinkage and basic creep. Several theoretical models have been presented to speculate on the mechanisms of this effect,...

Deformation of Concrete Due to Drying
The deformation of drying concrete is numerically investigated considering the effect of random arrangement of coarse aggregates. The result indicates that a part of the statistical variation...

Use of Stabilized Fly Ash for Seepage Control

Environmental Requirements of Lysimeters
Some of the more common environmental problems affecting measurement of evapotranspiration (Et) with lysimeters are discussed, including deviation...

Use of Lysimetric Measurements for Designing Major Irrigation Systems in the USSR
The bioclimatic method for calculation of crop water requirements has been widely used in the USSR in recent years. The author has analyzed the results of its application for designing...

Demonstration of an Infiltration Evaluation Methodology

Neutron Physics Considerations in Moisture Probe Design
Neutron physics can be used to characterize most of the know behavior of neutrons in the soil. Scattering, absorption and slowing down are the principal processes affecting moisture probe...

Factors Affecting Neutron Gauge Calibration
Neutron gauge characteristics and soil chemistry affect gauge calibration. External factors also influence gauge calibration and should be considered in the calibration procedure. Gauge...

Comparison of ET Measured with Neutron Moisture Meters and Weighing Lysimeters
The neutron moisture meter (N.M.) method of determining crop water use is frequently used in research and irrigated agriculture. This study was conducted to compare crop evapotranspiration...

Application of Neutron Soil Surface Water Monitoring for Plant Establishment
Soil surface water content measurements are tedious and time consuming, and to improve on such tasks, a neutron surface moisture probe was modified by using cadmium shielding. This prevented...

Practical Approaches Used in Neutron Meter Moisture Monitoring
This paper describes a practical, appropriate methodology for utilizing neutron meter soil moisture measurements to provide irrigation management information to farmers. A neutron meter...

Recognition and Avoidance of Details That Adversely Affect the Performance of Exposed Wood Members
Factors that affect the deterioration of wood in structures are reviewed. Important points regarding wood-moisture relationships are noted. The requirements for decay of wood by fungi...

Curing Time for CRCP Mixtures Based on Flexural Strength
In this paper, the effect of different curing conditions on the flexural strength is investigated, and also the minimum required period for moist curing is found. The combined effect of...

Instrumentation of Landfill Cover Liners: Moisture Transport Studies
Accurate estimation of the amount of water leaking through the cover liner, into the landfill, is vital for estimating the possible amount of leachate that can be generated into a landfill...
