Forecasting approach
Regional beach erosion and coastal flooding hazards are forecast using the Storm Hazard Matrix described in Leaman et al. (2021) Daily forecasts for the next 7-day period are undertaken every 100 meters along the coast for sandy beaches within the pilot regions. Further details on the forecast approach will be provided in a publication in prep.
Beach erosion hazards
| Category | Description | Diagram |
|---|---|---|
| Minor beach narrowing | Beach expected to experience minor erosion or accretion |
|
| Substantial beach narrowing | Pre-storm beach width is expected to reduce by 50% |
|
| Dune face erosion | Dune toe is eroded, but the dune crest is not impacted |
|
| Dune retreat | Dune crest is eroded, potentially impacting assets and worsening coastal flooding |
|
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 | Dune is completely submerged |

Wave and storm surge forecasts
7-day wave forecasts are based on the Australian Bureau of Meteorology's operational wave forecast system AUSWAVE. This has been extended to include more detailed information at the coast. For further details see Zieger et al. (2023). Storm surge forecasts are based on the Australian Bureau of Meteorology’s National Storm Surge Forecast System.
