Permeability Dataset for Great Britain (Mass Movements)
The data comprises GIS layers representing the permeability of mass movement deposits for Great Britain. The permeability data has been derived from DiGMap-GB (Digital Geological Map Data of Great Britain), and therefore reflects the scale of DiGMap-GB. For the majority of the Great Britain, the scale is 1:50,000,. The data is updated annually, or after a major new release of DiGMap-GB. The permeability data describes the fresh water flow through mass movement deposits and the ability of a unit to transmit water. Maximum and minimum permeability indices are given for each geological unit to indicate the range in permeability likely to be encountered and the predominant flow mechanism (fracture or intergranular). Neither of the assigned values takes into account the thickness of either the unsaturated or saturated part of the lithostratigraphical unit. The data can be used freely internally, but is licensed for commercial use. It is best displayed using a desktop GIS, and is available in vector format as ESRI shapefiles and MapInfo TAB files.

Data Quality
The data is derived from DiGMap-GB 50. Each lithology that occurred in DiGMap-GB was reattributed with permeability data. The maximum and minimum permeability indices were given for each geological unit along with the predominant flow mechanism. Hydrogeologists from BGS Wallingford and Edinburgh completed the attribution in Microsoft Access. This data was then joined to the DiGMap-GB GIS data in ESRI's ArcGIS. Each data layer is split into ten geographical areas to make them easier to display and interrogate. These include England and Wales - South East, England and Wales - South West, England and Wales - East Midlands, England and Wales - West Midlands and Wales, England and Wales - North East, England and Wales - North West, Scotland - East, Scotland - West, Scotland - North East, and Scotland - North West.
