Description: These maps have been produced to meet SEPA’s duty to publish flood hazard maps as set out in the Flood Risk Management (Scotland) Act 2009. The maps show where there is a risk of flooding from the sea, from rivers and from surface water.The following probabilities are available for river flooding: - High - 10 year return period - Medium - 200 year return period - Low - 1000 year return period and 200 year return period plus climate change using the UKCP09 high emissions scenario for the 2080s.The river hazard maps show (where available): - Flood extent - Flood depth - Flood velocities where appropriate. The climate change scenario has been defined by United Kingdom Climate Projection 2009 (UKCP09) predictions for 2080s high emissions 67th percentile.
Description: The following probabilities are available for surface water flooding: - High - 10 year return period - Medium - 200 year return period - Low - 200 year return period plus climate change using a 20% uplift in rainfall intensity for the 2080s based on DEFRA guidance (2006).The surface water hazard maps show (where available): - Flood extent - Flood depth - Flood velocities where appropriate.
Description: The following probabilities are available for coastal flooding: - High - 10 year return period - Medium - 200 year return period - Low - 1000 year return period and 200 year return period plus climate change.For most of Scotland, the climate change scenario used the UK Climate Projections 2009 (UKCP09) high emissions 95th percentile relative sea level rise projections for the year 2080. For the Outer Hebrides, UK Climate Projections 2018 (UKCP18) Representative Concentration Pathway 8.5 (RCP8.5) 95th percentile relative sea level rise projections for the year 2100 were used.The coastal flood hazard maps show (where available): - Flood extent - Flood depth.
