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...

Pervious Concrete
Pervious concrete consists of a hydraulic cementitious binding system combined with an open-graded aggregate to produce a rigid pavement with typically 15% to 25% interconnected void space....

Grid Pavement
Open grid pavements consist of concrete or plastic units with large surface openings filled with a permeable joint material, typically small aggregate (ASTM No. 8 or No. 89), sand, or...

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...

Hail Concepts
Hail, the product of vigorous deep convection, requires those same conditions that are conducive to the development of thunderstorms. These conditions include water vapor, especially in...

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...

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...

Performance-Based Design: Concepts in Geotechnical Earthquake Engineering

Performance-Based Design Method (PBDM)
This chapter discusses the performance-based design method (PBDM). Topics include performance objectives; recommended analysis methods; modeling guidance; preliminary proportioning; acceptance...

Watershed-Based Permitting — A Myth or Reality?
The United States Environmental Protection Agency has promulgated the Total Maximum Daily Load process to achieve the goals of the Clean Water Act. The TMDL processis applied to water...

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...

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...

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...

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...
