Belfast flood risk profile

Belfast has a history of significant flooding from both fluvial and pluvial sources. Due to its geographical location, topography, and population density, Belfast accounts for a large proportion of Northern Ireland's area at significant flood risk and faces substantial risks to human life, property, and key services.

Belfast has a long history of flood events and significant damage has been caused by both fluvial and pluvial events. Given the geographical location, topography and population density of the city, the potential adverse consequences to human life and property in Belfast are predicted to represent a large proportion of the Northern Ireland total. The coastal and pluvial flood risks are also both sensitive to environmental change. There is a significant number of key services likely to be affected on an annual average basis by some type of flooding. It is therefore not surprising that Belfast accounts for a large proportion of the total geographical area in NI that is estimated to be at "significant‟ risk of flooding.
