This Bridge Monitors the Environment and Harnesses Tidal Energy
The “smart” Memorial Bridge spanning the Piscataqua is outfitted with a tidal turbine and more than 40 sensors.
Historic Solutions to Sea Level Rise May Help Modern Communities
Earthen mounds helped ancient Dutch settlers thrive in coastal flood zones. Could historical engineering help us fight against rising seas?
Island Building Alters Waters Leagues Away and for Years After
Quantifying the impacts of dredging through satellite remote sensing could serve as a valuable resource in future geopolitical disputes over contested waters.
Forecasting Seismicity from Wastewater Disposal in Oklahoma
Mandated wastewater injection reductions in effect since 2016 are inadequate for preventing future, large-magnitude earthquakes in the state, according to a new induced seismicity model.
The Dangers of Glacial Lake Floods: Pioneering and Capitulation
During the past 70 years, Peruvian engineers virtually eliminated the risks posed by glacial lake floods. But climate change and a political blind eye are increasing the dangers once again.
Integrated Workflow Approach for Petroleum Engineering Problems
The author of a new book describes the challenges faced in making calculations for hydrocarbon exploration and extraction and how an integrated workflow approach can reduce uncertainties.
Double Threat to Solar Panels in Space
Protons accelerated in solar storms and electrons accelerated in geospace storms can reduce space mission lifetimes. What is the likelihood of extreme events during geospace storms?
Meteors Can be Used to Calibrate a Radar System
Every day meteors burn up in the atmosphere with highly predictable results, reflecting radio waves that could be used to calibrate antennas.
More Earthquakes May Be the Result of Fracking Than We Thought
Scientists show small earthquakes caused by fracking near Guy-Greenbrier, Ark., in 2010 that could have been early indicators of high stress levels on larger faults deeper underground.
