Simulating Radionuclide Transport Away from an Underground Nuclear Test: Linking Non-Isothermal Flow and Mechanistic Reactive Transport
The low-yield (0.75 kiloton) Cambric underground nuclear test situated in alluvium below the water table offers unique perspectives on radionuclide transport in groundwater. The Cambric...
Permits, Surface Water/Groundwater Baseline Sampling, and Analysis of Dewey-Burdock In Situ Uranium Project in Fall River County, South Dakota
Powertech Uranium Corporation has proposed to conduct in situ mining within a uranium enriched ore deposit on the proposed permit area known as the Dewey-Burdock project. The project is...
Maximum Weighted Log-Likelihood Estimation for Parameterization Selection Uncertainty
Hydraulic conductivity identification remains a challenging inverse problem in groundwater modeling because of inherent non-uniqueness and lack of flexibility in parameterization methods....
Viral Fate and Transport Modeling under Salinity Impact
This research studied the impact of salinity on sorption and transport of MS-2 in saturated sand through one-dimensional column experiments. MS-2 was used as a surrogate to understand...
Evaluation of IA SWAT Testing Protocol for ET Controllers
In recent years the Irrigation Association (IA) has developed a testing protocol for Smart Water Application Technologies (SWAT). These technologies consist of irrigation controllers such...
Hydrologic Comparison of Four Types of Permeable Pavement and Standard Asphalt in Eastern North Carolina
A permeable pavement parking lot in eastern North Carolina consisting of four types of permeable pavement and standard asphalt was monitored from June 2006 to July 2007 for hydrologic...
Non-Destructive Strength Evaluation of a Continuous, Reinforced Concrete Slab Bridge
In the state of New Mexico, a significant number of reinforced concrete slab (RCS) bridges provide service on interstate highways I-10, I-25, and I-40 that are subjected to large amounts...

History of the USDA-ARS Experimental Watersheds on the Washita River, Oklahoma
A national experimental watershed network, operated by the Agricultural Research Service of the US Department of Agriculture, was established in 1959 to conduct research on the effects...
Introduction
Permafrost is defined as soil that remains frozen for more than two years. At elevations less than 304.8 m (1000 ft.), it is frequently encountered north of latitude 60. It may also be...
The Need for Geotechnical Investigation
Knowledge of the subsurface conditions is needed to decide which type of foundation to use. In the discontinuous permafrost zone, some generalizations may be made about the location of...
Structurally Enhanced Foundations: A Functional Solution to Thaw Strain in Frozen Sand and Gravel
Some building sites with perennially frozen soil profiles are developed using nonelevated, conventional-appearing foundation systems. These sites consist of frozen sands and gravels and...
Post and Pad
As the name implies, this type of foundation consists of a concrete or wood pad placed on or buried in the ground. It is the lowest priced option for buildings on frozen silt, which may...
Adjustable Foundation Design Development Innovations in Arctic Engineering
The purpose of adjustable foundation systems is to accommodate a wide variety of soils, including those which have low bearing capacity or which may be subject to settlement and/or horizontal...
Some Case Histories of Pile Foundations in Permafrost
Foundations for permafrost conditions should conform to one of three basic design principles: keep it frozen, let it thaw, or thaw the ground before construction. To keep the permafrost...
Refrigerated Foundations
Refrigeration systems used to cool foundations on frozen ground can be classified as either active or passive, depending on whether external energy is used to power the systems. If pumps,...
