Researchers Use Electricity to Track Moisture Flow in Concrete
Electric currents create three-dimensional maps of moisture moving through concrete specimens, revealing internal cracks....

Ground Feature Monitoring Using Satellite Imagery: How Interferometric Stacking of SAR Can Mitigate Geo-Disasters Along Transportation Corridors
Landslides, debris flows, and other types of ground movements are among the most common hazards to humans and infrastructure. According to the United States Geological Survey, annual domestic...

Detailed Site Investigations
This section addresses site investigation issues that are important for detailed design and construction of microtunneling projects. These site investigations include the following: Geotechnical...

Radial Flow Consolidation Testing
A radial flow consolidation cell that can be used with commercially available loading frames was developed and a series of tests were performed on samples of sedimented kaolin. Simple...

Mechanisms Controlling the Permeability of Clays
Coefficients of permeability, calculated using Terzaghi's theory of one-dimensional consolidation, are reported for smectite, illite, and kaolinite, in water, methyl and ethyl...

A Fault-Rupture Propagation Model for Ground Motion Simulation

Hydrodynamic Damping on Flexible Cylinders in Sheared Flow

International Events Endorsed by the Geo-Institute, GeoHunan International Conference II, 5th International Conference on Debris Flow Hazards Mitigation, and IS-Seoul 2011.

Forces on a Large Cylinder in Random Two-Dimensional Flows

Dye-Vector Flow Visualization-Cooling Water Model

Watershed Modeling for Surface-Groundwater Interaction
Groundwater use has increased rapidly due to irrigation development in the Great Plains. This is especially true in the Republican Basin that intersects the three states of Nebraska, Kansas...

Groundwater Transport Modeling Using Fuzzy Sets and Fuzzy Logic
Modeling of groundwater flow and transport is inherently uncertain. The predictive capability of the model depends upon both the quantity and quality of hydrogeologic data. The introduction...

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...

Groundwater Flow Model Development at the Nevada Test Site
The Underground Test Area Project (UGTA) of the National Nuclear Security Administration.s Nevada Site Office is in the process of assessing and developing regulatory decision options...

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...

Transport Model Uncertainty and Sensitivity Analysis for Groundwater Releases of Radionuclides from Subsurface Nuclear Tests
Uncertainty analysis of groundwater flow and transport models is a topic of considerable interest in the groundwater modeling communities. The Underground Test Area (UGTA) Project of the...

Water Resources: California Reservoir Would Capture 'Nonstorable' Flows from Colorado River

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...
