MA - MIT scientists create device that will REBUILD island coastlines threatened by rising sea levels using the power of ocean waves to push sand toward the shoreline

A new research project from MIT could help save small islands and coastal towns threatened by rising sea levels around the world.

Led by MIT researcher Skylar Tibbits, the project uses ocean waves to move sand onshore and could be used to add to the overall landmass of at-risk islands or coastal towns.  

In early testing, the technology has added more than a foot and a half to the shoreline of a small island in the Maldives, moving the equivalent of 10,600 cubic feet of sand onto shore in four months.

'By collaborating with the natural forces of the ocean we believe we can promote the self-organization of sand structures to grow islands and rebuild beaches,' Tibbits said in an interview with MIT News.
