Short summary
A single storm event can change the shape of a sandy beach dramatically, but beaches also exhibit a remarkable ability to recover. So how important are storm-driven changes to a beach in the long term? This question affects predictions of future shoreline change. Here we explore signal shredding – when sediment transport erases any signature of outside driving forces. Our results suggest that major storm impacts may tell us little about long-term shoreline change and vice versa.
