Abstract

Historic Flood Outlines is a spatial dataset which outlines the maximum extent of all recorded individual Historic Flood Events Outlines from river, the sea and groundwater springs and shows areas of land that have previously been subject to flooding in Wales. It is also possible that the pattern of flooding in this area has changed and that this area would now flood under different circumstances. In addition, absence of coverage by the Historic Flood Map for an area does not mean that the area has never flooded, only that we do not currently have records of flooding in this area.

Quality and validity

Lineage

The data is updated every three months, but may not change quarter to quarter if there have not been any significant flood events in the preceding period. Flood outlines are digitised in ArcGIS from a number of sources including surveyed flood events. Please note that this map shows flooding to the land and does not necessarily indicate that properties within the Historic Flood Map were flooded internally. This dataset was update in May 2017 to include attribution data on the flood events. This was previously made available in the product "Recorded Flood Outline" which is no longer updated and no longer available.
