Coastal Flood (Future) - Hazard Extent - DCRRA
Potential coastal flood areas for a 200-year flood event (0.5% AEP) with climate change (2100).
Areas with potential coastal flood inundation for a 200-year flood event (0.5% annual exceedance probability) with climate change (2100). Includes sea level rise (2100), mean higher high water (MHHW), and storm surge.
Limitations
Coastal inundation extents in low-gradient areas such as river deltas are sensitive to the 30 m DeltaDTM vertical mean absolute error of 0.45 m. Oceanic data used in the analysis was converted from MSL and interpolated between data points, and the process of conversion and interpolation adds uncertainty in the flood layer. Oceanic data projections for storm surge and SLR were limited to the RCP8.5 scenario, which is representative of higher greenhouse gas emissions. SLR estimates include a predicted 1 m rise in sea levels at the end of century (2100) which may be revised with additional climate modelling. In gentle areas such as deltas, the outer boundary of flooded extents may show analysis spatial units disconnected from neigbouring waterways.
