Student Solutions
A multidisciplinary team of students from the University of Michigan worked at the Willow Run site in 2014 on a constructed wetlands system to help remediate contaminated groundwater....

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...

Dried Lakes Do Tell Tales: Seismic Soil Amplification in Mexico City
Mexico City is a vibrant, urban metropolis — a living and breathing example of an "old layered city," where past civilizations coexisted with one another. Standing more than 2.2 km above sea level, surrounded...

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...

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...

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,...
