Title

Hydrogeological Maps of Scotland version 2

Abstract

The BGS Hydrogeological Maps of Scotland data product is comprised of three datasets: Bedrock Aquifer Productivity (Scotland); Superficial Aquifer Productivity (Scotland); and Groundwater Vulnerability (Scotland). Aquifer productivity is a measure of the potential of aquifers to sustain a borehole water supply. The Aquifer Productivity (Scotland) datasets indicate the location and productivity of bedrock and superficial aquifers across Scotland, and their groundwater flow characteristics. The Groundwater Vulnerability (Scotland) dataset shows the relative vulnerability of groundwater to contamination across Scotland. The BGS Hydrogeological Maps of Scotland data product is developed as a tool to support groundwater resource management. It may be useful to anyone interested in learning more about, assessing or managing groundwater resources across Scotland. The datasets within the product are delivered at 1: 100 000 scale.

Lineage

The aquifer productivity data was developed in ArcGIS using BGS digital geology linework at a scale of 1:50,000: DiGMapGB-50, Version 5.18. Each of the geological formations in the 1:50 000-scale DiGMap superficial deposits geology map was classified according to the likely aquifer productivity. For a small number of map sheets, 1:50 000 scale superficial deposits mapping has not yet been done, and in these cases, superficial deposits linework and attribute data at other scales, including 1:625 000 scale, were merged in. Each of the geological formations in the 1:50,000 scale DiGMap bedrock geology was classified according to two criteria: (1) the predominant groundwater flow type (2) the estimated aquifer productivity of the formation. Input datsets include: BGS Geology 50K (formerly known as DiGMapGB-50 (Digital Geological Map of Great Britain at 1:50 000)) (Bedrock) Version 5.18 Permeability Dataset for Great Britain (Superficial) Version 6.0 (British Geological Survey 2010). The groundwater vulnerability dataset was produced in ArcGIS by combining a range of environmental datasets using a rule-based method to define a vulnerability classification. Groundwater vulnerability is described by one of five relative classes ranging from 1 (lowest vulnerability) to 5 (highest vulnerability). Input datasets include: BGS Geology 50K (formerly known as DiGMapGB-50 (Digital Geological Map of Great Britain at 1:50 000)) (Bedrock) Version 5.18 Permeability Dataset for Great Britain (Superficial) Version 6.0 (British Geological Survey 2010) Depth to groundwater level in superficial deposits (BGS) Depth to groundwater level in bedrock aquifers (BGS) HOST (Hydrology of Soil Types) Class from the James Hutton Institute (formerly the Macaulay Institute) Superficial deposits thickness (BGS)
