Abstract/Summary

The British Geological Survey (BGS) heat flow model version 1 (United Kingdom) is derived from a catalogue of legacy heat flow data points and ground-heat modelling. The model portrays heat flow as a continuous modelled surface, interpolated between observation and estimation points. Heat flow data is typically used to determine temperatures beneath the ground surface, and model how much thermal energy may be recovered from or stored within. The dataset is presented in three forms: 1) as a raster model covering the extent of the United Kingdom (UK), each cell of the raster model defined by a square polygon of area 4km2 (2km per side) attributed with heat flow as milli-Watts per square metre (mWm-2) 2) as a cellular, vector grid. Each raster cell/ record in the model is defined by a square polygon of area 4km2 (2km per side) describing heat flow as milli-Watts per square metre (mWm-2). This model directly vectorises the raster model. 3) as an alternative cellular vector grid: BGS Heat Flow V1_ Hex (United Kingdom), represented by hexagonal polygons of area 2.6 km2 (1 Km side length) describing summarised (minimum, maximum and average) heat flow per cell as milli-Watts per square metre (mWm-2). This model spatially resamples the raster data. The v1 release is based on legacy data and models last summarised in Busby et al. (2009). It does not incorporate the approximation of a regional paleoclimate correction presented in Busby and Terrington (2017). Users should note the limitation that the heat flow values presented in this model are underestimated, which would result in underestimation of geothermal resources at depth. This user guide provides the information required to enable the reader to understand and use this BGS product.
