BGS Base Data - Permeability

No sample image available

GB-wide 1:50,000 scale hydraulic conductivity (permeability) data. Permeability values indicate the vulnerability of the rock to groundwater pollution from the surface and are a measure of the fastest route by which any pollutant could travel through rocks and enter the underground water resource.

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 is best displayed using GIS, and is available in vector format as ESRI shapefiles and MapInfo TAB files. Please contact us at sales@emapsite.com for further details or a quote.
