Summary

PLEASE NOTE: This dataset has been retired.

‘Flood Depth Grid 20 meters’ is a national modelled dataset that shows flood depths on a 20x20 metre grid. These have been created using a Digital Terrain Model re-sampled to 20 metres and 1 in 1000 chance in any given year fluvial level scenarios. Depth levels that fall below 0 or greater than 10 metres have been filtered out.

Information Warnings: This is a national product that has not been quality assured.

It is useful for indicating which areas may be deeper or shallower but isn’t a substitute for local detailed modelling information where available.
