Sea on land is a screening model, not for property-level decisions. With defences: England uses EA surveyed crest heights; Wales and Scotland defence heights are estimated from 30 m terrain; Northern Ireland has no open defence data. Without defences shows land lying below the sea level. Terrain: DeltaDTM v1.1 (Pronk et al. 2024, CC BY 4.0). Water levels: EA Coastal Flood Boundary 2018 (OGL v3). Defences: EA AIMS, NRW, NatureScot Dynamic Coast (OGL v3). After 2100: UKCP18 exploratory projections to 2300 (illustrative; ice-sheet instability not represented), then each location continued at its 2280–2300 rate to 2520 — not a prediction. IPCC AR6 cannot rule out more than 15 m of rise by 2300 under high emissions. Sea level: PSMSL; UKCP18 (Met Office, OGL v3). Boundaries: ONS (OGL v3).
