An electrical stimulation technique turns beach sand into "natural cement," offering cost-effective coastal protection.

As efforts step up to protect coastal regions affected by erosion, scientists have found an unexpected way to protect communities—zapping the shoreline with electricity.

In a study published in the journal Communications Earth and the Environment, researchers from Northwestern University demonstrated the novel technique to strengthen marine sand, potentially offering a sustainable solution to combat erosion caused by climate change and rising sea levels.

“Over 40 percent of the world’s population lives in coastal areas,” Alessandro Rotta Loria, who led the study, said in a statement.

“Because of climate change and sea-level rise, erosion is an enormous threat to these communities. Through the disintegration of infrastructure and loss of land, erosion causes billions of dollars in damage per year worldwide,” he said.

    This sounds more useful to apply to specific, small portions of the sand, rather than applying it to an entire coastline.

    “We can use it to strengthen the seabed beneath sea walls, stabilize sand dunes and retain unstable soil slopes. We could also use it to strengthen protection structures, marine foundations and so many other things. There are many ways to apply this to protect coastal areas.”
