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 interested specifically in debris flow susceptibility at a regional or national planning scale such as those involved in construction or maintenance of infrastructure networks (road or rail or utilities), or other asset managers such as for property (including developers and home owners), loss adjusters, surveyors or local government. The dataset builds on research BGS has conducted over the past 15 years investigating debris flows. The model was designed to identify potential source-areas for debris flows rather than locate where material may be deposited following a long-run-out failure i.e. the track and flow of debris. This work focuses on natural geological and geomorphological controls that are likely to influence the initiation of debris flows. It therefore, does not consider the influence of land use or land cover factors.

The Geological Controls on Infiltration v8 dataset (based on BGS Superficial and Bedrock Permeability v8 data) has also been created as an input to the BGS debris flow model. An Ice-scoured domain polygon was created for the model using a combination of a Quaternary Domain Map and a Landslide Domain Map created by BGS scientists. The data has been analysed, processed and combined within a Geographical Information System (GIS) environment following a methodology derived with BGS engineering geologists and data scientists to produce the resultant model.
