Crews race to contain California oil spill
The Weather Channel -
Kristen Davis, UCI associate professor civil & environmental engineering and principal investigator, Coastal Dynamics Lab said, “The spill has a local effect, while that is a visible effect that we will be dealing with it for years, as far as wildlife and the cleanup, I also think it is important to realize that the effect of fossil fuels is much broader than the spill that we are seeing here today. And that we have a big challenge ahead of us as we go into the COP26 international climate talks in Glasgow next month. I hope that this spill is a wakeup call to get serious about getting off of fossil fuels.” Read More
Building An Alternative to GPS
IEEE Spectrum -
"There is an urgent need to find an alternative robust and accurate navigation system to GPS," says Zak Kassas, an associate professor [of engineering and ICS] at University of California, Irvine, and Director of US Department Transportation Center for Automated Vehicles Research with Multimodal AssurEd Navigation (CARMEN). "We are over-relying on these systems, despite their known limitations." Fortunately, Kassas and his colleagues have devised a novel substitute for GPS. Read More
Newsletter: A look back at the week in Opinion
Los Angeles Times -
Southern California’s beaches are running out of sand. So we’re losing our majestic mountain forests and our beaches now? The difference with the disappearing sand is that so far, climate change isn’t the proximate cause, writes UC Irvine engineering professor Brett Sanders: “Local development and land use have altered natural processes that would have otherwise replenished the beaches. Sand on beaches is a lot like money in a bank account. It flows in and out, and the balance needs to stay in positive territory to avoid a calamity of problems.” L.A.

Coastal erosion in San Clemente threatens railroad tracks, pricey homes
Los Angeles Times -
After decades of development that destroyed countless acres of coastal marsh, Southern California’s environmental “bank account” is empty, said Brett Sanders, professor of civil and environmental engineering at UC Irvine. … For Sanders, San Clemente is an ideal place for a project that rebuilds beaches and ultimately protects the railroad track and houses. But it will take quick action from regional leaders, he said. [Subscription required, you can request an electronic copy of the article by sending an email to communications@uci.edu.] Read More
Avoiding water bankruptcy in the drought-troubled Southwest: What the US and Iran can learn from each other
Public Radio International -
Amir AghaKouchak, UCI professor of civil & environmental engineering and others write, “More than 7,000 miles away, Iran is grappling with water problems that are similar to the U.S. Southwest’s but more severe. … As environmental engineers and scientists … we’ve closely studied the water challenges in both drought-prone regions. We believe past mistakes in the U.S. and Iran offer important lessons for future plans in the U.S. Southwest and other regions increasingly experiencing drought and water shortages.” Read More
Why the "Swiss Army knife" of climate solutions is so controversial
Salon -
Jack Brouwer, director of the Advanced Power and Energy Program at the University of California, Irvine, where he conducts research on a broad range of hydrogen applications, told Grist that commercially available power plant technology can currently burn a blend of up to 30 percent hydrogen gas and 70 percent methane. … For Brouwer, blending green hydrogen into the natural gas system, whether for power plants or homes, is still very much worth doing — not so much for the greenhouse gas benefits, but to create a new market for solar and wind power.

Op-Ed: Southern California’s beaches are running out of sand
Los Angeles Times -
Brett Sanders, is a UCI professor of civil and environmental engineering, urban planning and public policy. He leads the UCI Flood Lab and the Metropolitan Beaches Project and writes, “Southern California’s sandy beaches are under duress and need our help. … So far this isn’t primarily about climate change or rising sea levels. It’s about how local development and land use have altered natural processes that would have otherwise replenished the beaches. Sand on beaches is a lot like money in a bank account. It flows in and out, and the balance needs to stay in positive territory to avoid a calamity of problems.” Subscription required, you can request an electronic copy of the article by sending an email to communications@uci.edu.] Read More
Researchers use Starlink satellites to pinpoint location, similar to GPS
Ars Technica -
Signals from SpaceX Starlink broadband satellites can be used to pinpoint locations on Earth to within eight meters of accuracy, engineering researchers reported in a new peer-reviewed paper. … The research was conducted by [Zak] Kassas along with Joe Khalife (a postdoctoral fellow at the University of California, Irvine) and Mohammad Neinavaie (a Ph.D. student at UC Irvine). Kassas is also a UC Irvine [assistant] professor and director of the Autonomous Systems Perception, Intelligence, and Navigation (ASPIN) Laboratory, while Khalife and Neinavaie are members of the lab. Their experiment was conducted using an antenna on the UC Irvine campus. Read More
SpaceX's Starlink broadband satellites could be used for GPS navigation
Space -
SpaceX's Starlink satellites may be used for navigation and global positioning in addition to their core function of broadband Internet, a new research study suggests. … "We eavesdropped on the signal, and then we designed sophisticated algorithms to pinpoint our location, and we showed that it works with great accuracy," study author Zak Kassas, director of the Center for Automated Vehicles Research with Multimodal Assured Navigation (CARMEN) at Ohio State University, said in the statement. … They used the signals from several satellites and developed an algorithm to locate a position on Earth. Next, they placed an antenna on the University of California, Irvine campus in an attempt to find its location using Starlink. Their experiment placed the estimated position of the antenna, using Starlink signals, within 25 feet (7.7 m) of its actual position. Read More
