The North Kent 3D geological model was commissioned by the Environment Agency to gain a better understanding of the structure of the bedrock in the area to help understand groundwater movement; this report contains the model metadata, for the full report see Farrant et al. (2015). The GSI3D (Geological Surveying in 3D) software was used to construct the model, following the established workflow described in Kessler et al, (2009). The model comprises 30 correlated cross-sections constrained by 290 boreholes held in the BGS archive. Figure 1 shows the distribution of boreholes and correlated cross-sections.
This model is of the bedrock and superficial geology of an area along the proposed route of the High Speed Rail link between London and Birmingham (HS2). It covers the section of the HS2 route between Thorpe Mandeville in Northamptonshire and Ladbroke in Warwickshire. The bedrock geology of this section of the route comprises Triassic to Middle Jurassic strata, together with superficial deposits of glacigenic and fluvial origin. This is one of nine models along the proposed route. It is suitable for use at scales between 1:100,000-1:10,000, down to a depth of 30 m below OD.
Prior to the modelling work, an assessment of the quality and availability of the digital geological linework and existing 3D models of the whole HS2 route between London and Birmingham was undertaken (Barron et al., 2012). As a consequence of this review, the geological mapping of this sector was deemed to be adequate, dating from the 1950’s to the 2000’s. Thus this 3D model is based on geological line work from existing 1:10 000 and 1:50 000 scale DiGMapGB data.
