Schematic diagram showing two scenarios for coastal flood events affecting a row of houses. In the first scenario, Panel 1 shows a narrow beach separating a row of houses from mean sea level. Panel 2 shows flood waters rising above the narrow beach and impacting the houses. In the second scenario, Panel 3 shows a wide beach separating the houses from mean sea level. Panel 4 shows the wide beach continuing to separate the houses from the water during flood water levels.
