Forecasting approach
Regional beach erosion and coastal flooding hazards are based on key concepts presented in Leaman et al. (2021). Daily forecasts for the next 16-day period are calculated every 100 m along the coast for selected beaches within the pilot regions. Further details are provided in Turner et al. (2024).
Coast types

Beach erosion hazards
| Category | Description | Diagram |
|---|---|---|
| Minimal changes | Minimal beach changes |
|
| Moderate | Moderate erosion, associated with a 0.2-year ARI wave energy event |
|
| Substantial | Substantial erosion, associated with a 2-year ARI wave energy event |
|
| Extreme | Extreme erosion, associated with a 10-year ARI wave energy event |
|
Coastal flooding hazards
| Category | Description | Diagram |
|---|---|---|
| Swash | Total water level does not reach the dune toe and is confined to the beach area |
|
| Collision | Total water level is impacting the dune face |
|
| Overwash | Total water level overtops the dune crest |
|
| Inundation | Total water level completely submerges the dune |

Wave and storm surge forecasts
16-day wave forecasts are based on the National Oceanic and Atmospheric Administration (NOAA) operational wave forecast system WAVEWATCH III® . This forecast has been extended to include more detailed information at the coast. For further details see NOAA WAVEWATCH III Model Description. Storm surge forecasts are based on real-time observations from coastal tide gauges.
