BGS Debris Flow Susceptibility Model GB (version 6.1)

The BGS Debris Flow Susceptibility Model for Great Britain v6.1 is a 1:50 000 scale raster dataset of Great Britain providing 50 m ground resolution information on the potential of the ground, at a given location, to form a debris flow. It is based on a combination of geological, hydrogeological and geomorphological data inputs and is primarily concerned with potential ground stability related to natural (rather than man-made) geological conditions and slopes. The dataset is designed for those i

Useful for

Use cases llm-inferred: Regional-scale debris flow screening for linear infrastructure route options (rail, road, utilities) · Ground stability screening for asset management portfolios and property or loss adjusting desk reviews · Pre-desk-study screening to prioritise site-specific geotechnical investigation
Audience llm-inferred: civil engineers · geotechnical engineers · infrastructure asset managers · surveyors · loss adjusters · local government planners

Limitations

Constraints docs-verified: Does not consider land use or land cover influence · Designed to identify debris flow source areas, not deposition or run-out tracks · Intended for regional or national planning scale, not site-specific assessment · Natural geological and geomorphological controls only, not man-made conditions · No update schedule planned · NERC/BGS gives no warranty on accuracy or suitability; use is at the customer's own risk
