Geological Indicators of Flooding Great Britain

The BGS Geological Indicators of Flooding (GIF) dataset is a digital map based on the BGS Digital Geological Map of Great Britain at the 1:50,000 scale (DiGMapGB-50, BGS, 2009). Current coverage includes England, Wales and Scotland. It characterises Superficial Deposits on DiGMapGB-50 in terms of their likely susceptibility to flooding, either from coastal inundation or fluvial (inland) water flow. These Superficial Deposits are considered 'recent' in geological terms, most having been formed wi

Useful for

Use cases llm-inferred: Desk-based flood susceptibility screening of superficial deposits for FRA scoping · Identifying floodplain deposit types to support coastal and fluvial flood context in site assessments · Regional flood-risk context mapping for planning and drainage strategy baselines
Audience llm-inferred: flood consultants · engineering geologists · hydrologists · GIS analysts · planners

Limitations

Constraints llm-inferred: Covers England, Wales and Scotland only; Northern Ireland is not listed in current coverage · Mapped at 1:50,000 scale, so not suited to site-specific or parcel-scale flood assessment · Describes susceptibility of deposits, not flood extent, depth or probability · Based on 2009 DiGMapGB-50 mapping with a dataset reference date of 2006 · Reproduction and onward transmission restricted by NERC copyright · BGS gives no warranty on accuracy or suitability; use is at the customer's own risk · Licence field not set on the dataset page, so reuse terms should be confirmed with BGS
