GeoSure Extra: Debris Flow Susceptibility Model for Great Britain (Version 6.0)

Dataset description

The Debris Flow Susceptibility Model for Great Britain version 6.0 (DFSM_GB_v6.0) provides information on the likelihood of debris flows occurring at a given location based on a combination of digital geological, hydrogeological and topographic data. It is a raster dataset at 50m resolution, showing susceptibility for debris flows on a scale A (lowest likelihood) to E (highest likelihood). The methodology develops an additional dimension to the BGS GeoSure Landslides surface layer (Dashwood et al., 2014) and is designed for users interested specifically in debris flow susceptibility. The identification of debris flow hazards can assist regional planners; rapidly identifying areas with potential problems and aid local government offices in making development plans by helping to define land suited to different uses. Other users of these data may include developers, homeowners, asset owners, solicitors, loss adjusters, the insurance industry, architects and surveyors. The DFSM (Debris Flow Susceptibility Model) GB v6.0 was completed in March 2017.
