Extremestorms could help protect beaches from sealevelrise, new study finds NaturePortfolio
The study, led by Dr. Mitchell Harley from the UNSW Water Research Laboratory, is published today in"We know that extreme storms cause major coastal erosion and damage to beachfront properties", Dr. Harley says.
In Australia, researchers studied Narrabeen beach in Sydney in the wake of a 2016 storm which famously ripped a swimming pool away from a property overlooking the coastline. "We are not quite sure whether this extra sand has come from offshore or from around the corner, or even both, but we do now understand that extreme waves can potentially contribute positively to the overall sand budget, despite causing upper beach and dune erosion," said Professor Gerd Masselink, who leads the Coastal Processes Research Group.
"The Bruun rule however has been criticized for its simplicity, as it doesn't take into account the many complex factors about how individual beaches respond to sea-level rise," Prof. Masselink says.
