The Gold Coast Sand Bypass jetty extending into the Pacific Ocean, where submerged pumps move sand to prevent erosion and maintain navigation channels.

Australia fixed a beach that wouldn’t stop losing sand by building a “jetty” about 1,600 feet long and burying 10 pumps on the seafloor, and the scale is massive: moving about 654,000 cubic yards of sand a year through a pipeline roughly 4 miles long, and it’s been running since 1986
