The state of Louisiana is deploying giant 'pillows' of crushed rock to slow coastal erosion.
"The [Louisiana] state Coastal Protection and Restoration Authority has completed the first mile of a three-mile-long shoreline protection project that uses rock-filled pillows, each about the size of a small car, to slow land loss along the Rockefeller Wildlife Refuge in Cameron Parish," reports Tristan Baurick.
The rock pillows proved the most successful after a trial of experiments that included more traditional breakwater failed. "If successful, the $34 million project could be replicated along other stretches of the state’s coastline," according to Baurick.
