[Abstract] 

  Globally, erosion is accelerating along sandy coastlines. Between 1984 and 2016, 24% of beaches eroded at an annual rate of 0.5 metres (Luijendijk et al., 2018). Half of the world's beaches are projected to suffer loss due to sea-level rise (Vousdoukas et al., 2020). Beaches provide protective functions against sea-level rise, extreme events, and coastal erosion (Harris and Defeo, 2022). Beach erosion leads to land loss, damage to coastal property, infrastructure destruction, increased flood risk, and reduced tourism activity (Dong et al., 2024). In the United States, each state has its own unique coastal management policy, typically calculating set-back distances for individual structures based on the average annual rate of shoreline change (Williams et al., 2019). The calculation of set-back distances that fails to account for sea-level rise is highlighted as a problem within coastal management policy (Kirby et al., 2021). In the UK, the Coastal Erosion Risk Mapping under the Coastal Management Plan (SMP) has incorporated current sea level rise, but mapping for beaches remains incomplete as it fails to reflect the dynamic beach system (Kirby et al., 2021). Particularly, as the unit of measurement for retreat distance calculations is based on individual structures or individual plots, it is difficult to implement integrated coastal management policies for a single coastline that encompass structures, foreshore, and buffer zones.
