The disadvantages are that the ongoing costs are high as the sediment needs replacing every few years as waves remove it. The main type of erosion, from the sea, takes the sand from the sand dunes as well as the rest of the beach in a rip. By using this design there is less risk of further erosion as a result of the seawall and the seawall is hit with less force and is less likely to become damaged from the force of the waves in the near future. Last updated: 01/20/23 This story is part of a series inspired by the subjects and speakers appearing at BBC Futures World-Changing Ideas Summit in Sydney on 15 November. As coasts become more developed, the vulnerability component of the equation increases as there is more value at risk to the hazard. Losses of primary producers and important habitat-forming species such as corals can negatively impact entire food webs. Without these plants (and ultimately the sand dunes) sand will be subject to many natural forces without protection, meaning any major storm could theoretically remove large amounts of sand from the beach with no natural means of replenishing it. They pay roughly two-thirds to three-quarters of the cost, and The foreshore is most affected because it is where the waves are most frequently hitting that part of the sand dunes which means that erosion will occur faster there. For example, the vast majority of our nations commercial and recreational fisheries are dependent on coastal marshes.
