Street Smarts
Sensors, cameras, and other technologies are helping cities monitor and manage their streets better. Data from such "smart streets" are enabling engineers and other transportation experts to improve safety...

PFAS in Groundwater, Small Water Systems, and Water Reuse Receive U.S. EPA Scrutiny

We Struck Water! Discovery of Artesian Groundwater Solves A 50-Year-Old Landslide Puzzle
Some unstable slopes fail dramatically, but most can be characterized by gradual, if not monotonously slow, movements. Yet these latter situations can pose a dilemma when a temporary repair is much simpler...

Tucson Will Use Reclaimed Water to Recharge Groundwater, Revitalize River

Ground Improvement for Underground Construction: The Good, the Bad, and the Ugly
Underground construction is "special" because the work may be performed at great depths and under high groundwater pressures. All too often, it seems to take place in urban areas where there is limited...

Design Considerations Common To All Permeable Pavements
Impervious cover in watersheds without controls result in increased stormwater runoff and decreased groundwater recharge in response to rainfall events. This increased runoff can be the...

Hydrologic and Hydraulic Design Methods
Computational methods for hydrologic analysis, hydraulic functions, and treatment capacity of permeable pavements vary depending on the complexity of the design and level of detail in...

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...

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...

California Cities Develop Surface Water Supply to Reduce Dependence on Groundwater

Major Utah Groundwater Project Features State's Deepest Wells

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...

Ground Freezing in a Congested Urban Area
Artificial ground freezing is a method of providing temporary earth support and ground water control for deep excavations and tunnels. The technique has been used for over 100 years in...
