Smarter sand replenishment: Local lawmakers have fought for years to get the millions of dollars needed to start sand replenishment projects to help reverse erosion of Southern California beaches caused by development, rising seas and other impacts of climate change. But Laylan Connelly reports that UC Irvine researchers are recommending new data and methods that could allow leaders to make smarter decisions about where sand infusions can do the most good.

New UCI study shows how data can help deal with eroding beaches
KNX News -
Not all beaches are eroding, but many are - enough to warrant spending large sums of money to add sand to Southern California's deteriorating coastlines. But as a new study out of UC Irvine suggests, adding sand might not be the way to go in every case. KNX News reporter Nataly Tavidian spoke with Daniel Kahl, a UC Irvine Ph.D. student who heads the study. Read More
UC Irvine sand study shows new data to help manage shrinking beaches
The Orange County Register -
A new paper published recently by UC Irvine researchers in the Coastal Engineering Journal analyzed beaches between Long Beach and La Jolla, offering new data and methods that can be used to figure out the most vulnerable areas of coastline and whether those beaches are suitable for the mega, costly projects often turned toward for trying to replenish and retain sand. … “I’m really excited to have the resources that help, potentially, inform these decisions,” said Daniel Kahl, UCI researcher and lead author of the paper. … “The data essentially shows: Where do we get the most bang for our buck when it comes to placing sand on the coast,” said Brett Sanders, UCI civil and environmental engineering professor and co-author of the published paper.

During LA's historic rain, river was 'doing exactly what it was engineered to do'
SFGate -
Experts have also found that the [LA] river’s flood protection abilities need shoring up, especially as the region sees more intense storms due to climate change. One 2022 study from the UC Irvine Flood Lab found nearly a million people are exposed to flooding during a 100-year storm event, with the most intense impacts on cities along the southern part of the river, like Bell Gardens and Compton.

With the state mandating zero emissions, Bay Area agencies are split on hydrogen vs. electric
The Mercury News -
According to Jack Brouwer, director of the National Fuel Cell Research Center and the Advanced Power and Energy Program at UC Irvine, deciding the right number and type of zero-emission buses depends on many factors, including the electrical grid infrastructure, the bus routes, and the road type. Battery electric buses, for example, consume more power on hilly roads. Read More
California’s Flood Defenses Held This Time, but They Are Weakening
The Wall Street Journal -
“The infrastructure is optimized to move water quickly to the ocean, and it did its job,” said Brett Sanders, a professor of civil and environmental engineering at the University of California, Irvine. “But had we had another storm right after that, we might have gotten close to the limits of that system.” A 2022 report from UC Irvine determined that a 100-year flood event in Los Angeles would expose more than 400,000 people to danger, with property damage of more than $50 billion, comparable to that of a major hurricane.

How California’s storms are projected to become more extreme with climate change
Los Angeles Times -
“Higher rain over snow ratio, faster snowmelt, and more intense storms can significantly impact water resource management in California,” said Amir AghaKouchak, a UC Irvine professor of civil and environmental engineering. “A shift toward more intense rain, as opposed to snow, will strain an already water-challenged environment to its limit.” … In a 2022 study, researchers at UC Irvine found that in the Los Angeles Basin, nearly 1 million people live in areas that could be threatened in a 100-year flood, and that Black and low-income communities are especially vulnerable.

Climate change will bring megafloods to California
BBC -
"San Diego flooding two weeks ago showed again that disadvantaged communities bear the brunt of flood impacts when infrastructure is overtopped," says Brett Sanders, professor of civil and environmental engineering at the University of California, Irvine. "If this storm ends up causing mainstem flood channels to overtop, then once again there will be low-income communities impacted, leaving people scrambling to salvage their belongings and find a place to live while not losing their job from missed work."

L.A.’s flood-control system survived epic storm. But it’s losing battle with climate change
Los Angeles Times -
Scientists suggest that epic storms to come will challenge the county’s aging flood-control system. A recent UC Irvine study suggests that a 100-year flood — a deluge that has a 1% chance of occurring in any given year — could rapidly overwhelm the area’s principal waterways: …. “All we initially wanted from the infrastructure was economic development and safety from flooding,” said Brett Sanders, a professor of civil and environmental engineering at UC Irvine and co-author of the study published in the scientific journal Nature Sustainability. “So, what we’ve got are concrete race tracks that sweep water into the Pacific Ocean as quickly and efficiently as possible.” Read More
Why record rain hasn’t washed away California’s water woes
The Washington Post -
More places will have to develop robust programs to restore groundwater that provide multiple “access points” for surface water to seep into the aquifer, University of California, Irvine civil engineer Brett Sanders said. Large basins serve as primary access points for groundwater to filter downward, holding large amounts of runoff and recycled wastewater that trickle into aquifers. Communities also must add smaller green spaces to improve storage and prevent flooding by helping more water get into the ground, he said. Read More
