Go Online, Young Engineer!
One stereotype involving social intranets might be that younger engineers will use such systems more quickly or enthusiastically than older engineers—perhaps because the young engineers have grown up using...

A New Approach to Mitigate Subsidence Problems: A New Approach to Mitigate Subsidence Problems
Mexico City has a decades-old problem with severe consequences: its lacustrine zone is subsiding due to pumping of potable water from the main aquifer. The geotechnical team assigned to work on the problem...

An Unknown-Unknown Does In An Overpass: A Soil Stockpile on Soft Clay Is Too Much for a Bridge in Canada
Like most structures, bridges are designed for an array of loading conditions. Some loads are known or can be reasonably estimated with confidence (i.e., known-knowns, such as structure dead and vehicular...

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...

The State of Soil Improvement in China: The G-I Soil Improvement Committee’s China Scan Tour
During the last four decades, China has made significant improvement in various sectors of its infrastructure, including high-speed railways, long-span and cross-sea bridges, large dams, long- and large-diameter...

Geotechnics of the Suez Canal Construction: 150 Years Old, but Nearly Four Millennia in the Making
Construction of the Suez Canal created one of the most important waterways in the world, connecting the Mediterranean and Red Seas. Its construction from 1854 to 1869 created three cities, Port-Said, Ismailia,...

Forecasting Method Could Improve Tsunami Warning
Researchers at Stanford University in California have developed a new method to analyze water pressure at the ocean floor, potentially offering better accuracy in forecasting tsunami wave heights....

Storage for One More Century
Since its completion more than a century ago by a previous owner, Denver Water's Antero Dam has experienced seepage problems, forcing the utility to limit the storage capacity of the associated reservoir....

Solutions for Soft Soils
Because of highly permeable soils and high water tables, deep foundations and basements in southeast Florida have been virtually impossible, limiting the excavation depths in cities like Miami and leading...
