“Reefs can effectively protect shorelines because of their ability to cause waves to break offshore, thus limiting the energy impacting the coastline,” said lead researcher Dr. Michael Cuttler, in a press release. Dr. Cuttler and his team studied the effects of a cyclone in 2015, and found that the shoreline was protected by the offshore reef. “The large waves generated by the cyclone were effectively dissipated by the reef situated offshore.” Dr. Cuttler explained,”The little erosion that did occur was due to smaller waves that were generated by wind within the lagoon. In this study, we also compared similar cyclone impacts on coastlines without reefs and found that these beaches were eroded up to ten times more than the beach at Ningaloo.” The team suggested that this reef is similar in geomorphology to other fringing reefs across the world, allowing the findings to be translated to other coastal areas. They also believe that as global warming and sea level rises continue: “These changes may ultimately increase the amount of wave energy reaching the coastline and potentially enhance coastal erosion.” Journal Reference:
