On Martian Soil
Discussions are ongoing about how and when to build human settlements on other worlds. Many scientific discussions have focused on settlements on Mars, and how the initial colonists would...
Environmentally Friendly Transport of Reservoir Sediment for Beach Nourishment with EDDY Pump
Sand impounded behind hydroelectric, flood-control and debris dams not only diminishes the intended function of the reservoir, but also starves downstream coastline by denying natural...
Towers in Motion (available in Structural Engineering Special Section only)
Undersea towers are typically designed to rigidly resist the forces of water and wind. But one type of tower is designed to be flexible and, rather than rely on its platform strength to...
Monitoring the Fresh Kills Landfill (Available in the Geoenvironmental Special Section only)
A unique system has been developed to assess the stability of the Fresh Kills Landfill, in New York City, using more than 260 geotechnical instruments and automatic processes. The system...
