Can artificial intelligence save sầu the L.A. water supply from a big earthquake?

thithptquocgia2016.com researchers have embarked on an innovative sầu project to prove that it can. Using federal funds, experts at the thithptquocgia2016.com Center for Artificial Intelligence in Society (CAIS) are working with Los Angeles thành phố officials lớn find solutions for vulnerable plumbing. The goal is to make surgical improvements to strategic pipelines to keep water flowing after shaking stops.

“L.A.’s water pipes are highly sthithptquocgia2016.comeptible to earthquakes,” said Bistra Dilkina, assistant professor of computer science at the thithptquocgia2016.com Viterbi School of Engineering và associate director of the CAIS. “The infrastructure is aging, and when the shaking starts, pipes break và damage propagates throughout the system. It’s a problem we’re trying khổng lồ solve sầu.”

The project is part of a larger national retìm kiếm effort using AI for societal good involving scientists at thithptquocgia2016.com. It is a response lớn recent manmade và natural disasters, such as Hurricane Katrimãng cầu in 2005, the Deepwater Horizon oil spill in 2010 & the Haiti earthquake of 2010.

Rapid gains in computer science fields lượt thích AI & machine learning are increasingly utilized for practical problem-solving in the private sector. Increasingly, government agencies are viewing these technologies as a way lớn protect lives và reduce costs.

Enter the City of L.A. & its Department of Water & nguồn (DWP). As part of the city’s Resilience by Design program, it plans to spend $2.85 billion in the next 10 years lớn upgrade & replace critical infrastructure, about half of which will go toward replacing priority water mains.

Preparing the L.A. water supply for disasters

The work dovetails with efforts to lớn adapt the city’s water supply for drought and climate change risks while improving local water sources. L.A. imports about 85% of its water via aqueducts vulnerable to lớn quakes across Southern California. The “seismic-resilient pipe network” project with thithptquocgia2016.com would tư vấn those efforts with a goal khổng lồ minimize interruption of water for critical functions.

City officials are particularly concerned about water available for firefighting in the aftermath of a big quake. According lớn a risk assessment prepared by the DWP, hundreds of fires could erupt in the L.A. basin if faults beneath the metropolis rupture. Firefighting capabilities were compromised due khổng lồ water pipe breaks after the Northridge earthquake, & fires destroyed much of San Francisco in the aftermath of the great quake of 1906.

“With this retìm kiếm, we hope lớn get a better understanding of the layout of the city from a critical infrastructure & strategic firefighting perspective,” said Aaron Gross, chief resilience officer for the City of L.A. “By mapping out where critical infrastructure is và using artificial intelligence to map out other critical functions of the thành phố, we can better plan for where khổng lồ harden our water infrastructure; more specifically, where khổng lồ target deployment of earthquake-resistant pipes.”

The DWPhường. maintains about 7,000 miles of water pipe, which serve sầu roughly 4 million people over a 465-square-mile area. About 30% of the city’s original cast iron water pipes are more than 80 years old and approaching the kết thúc of usefulness. About 14 miles of pipe are slated for replacement next year, a rate that stresses the critical need to determine how and where khổng lồ nâng cấp.

The goal is to lớn identify critical public safety facilities — such as hospitals, fire stations, police stations và evacuation centers concentrated in select locations — where pipeline upgrades can make a big difference in a disaster. In addition, Gross said the đô thị hopes khổng lồ provide a failsafe network of quake-resistant pipes so firefighters can always be within one mile of a water source to fight urban fires.

How AI can help prepare for an earthquake

It’s the sort of optimization challenge for which AI is perfectly suited, Dilkimãng cầu said.

AI has the ability khổng lồ simulate many computations & scenargame ios across layers of data và maps lớn create computer models lớn tìm kiếm for the best options that tài khoản for the whole picture, rather than piecemeal decisions for individual pipes. With those results, engineers can concentrate pipeline upgrades strategically at key junctures và the most vulnerable sections without having lớn nâng cấp every piece of pipe. AI gets the job done faster because it employs algorithms lớn sort complexity.

If we identify where there’s risk and critical customers, then we can build a subnetwork that can persist và survive an earthquake.

“We want lớn replace aging, old pipes with quake-resistant pipes. But where lớn invest in new plumbing? If we identify where there’s risk and critical customers, then we can build a subnetwork that can persist và survive an earthquake,” Dilkimãng cầu said.

Recent California quakes suggest making pipelines quake-ready is good sense.

In the aftermath of the 6.4 & 7.1 magnitude Ridgecrest earthquakes in July, engineers identified multiple pipeline ruptures. During the 6.7 magnitude Northridge quake, busted water mains flooded some city streets.

Experts at the U.S. Geological Survey (USGS) & the Southern California Earthquake Center (SCEC) at thithptquocgia2016.com estimate a one-in-five chance of a 7.0 magnitude or greater quake on the southern San Andreas Fault within 30 years. That section of the fault arcs from the Salton Sea through Cajon Pass to lớn Palmdale; it has been identified as the likely source of The Big One, a major quake that would slam the sprawling L.A. region. Also, the odds of another Northridge-form size quake in the metro L.A. basin are about 60% over the next three decades, the report says.

A hypothetical scenario by the USGS, assisted by SCEC, shows that a big quake on the southern San Andreas Fault would cause extensive sầu damage khổng lồ the water systems và aqueducts that tư vấn L.A.

Dilkimãng cầu, the principal investigator, said the retìm kiếm will take one year to lớn complete, after which findings will be submitted lớn city officials và later submitted for publication in a scientific journal.

The seismic-resilient pipe network project for DWP is funded by a $280,000 grant from the Critical Infrastructure Resilience Institute, a U.S. Department of Homeland Security center at the University of Illinois at Urbana-Champaign.
