Statement

This dataset is derived in part from BGS DiGMapBG-50 data attributed with BGS Permeability Index data, from groundwater levels from BGS WellMaster database and from regional hydrogeological contours taken from the IGS series hydrogeological maps. The data has been produced using a 'rule-based' approach. The first step was to apply 'rules' to identify areas, based on geological considerations, where groundwater flooding could not occur, i.e. areas where non-aquifers are present at the ground surface. For all areas that were geologically susceptible, a second suite of rules was used to produce a national groundwater level surface using data taken from published BGS groundwater level contours, groundwater levels in BGS WellMaster database and inferred from some river levels. A further suite of rules was used to modify this groundwater level surface so that it was representative of conditions of groundwater flooding. Finally, this modified groundwater surface was compared with a digital terrain model (DTM) of the ground surface elevation and a final set of rules was used to zone the degree of susceptibility depending on the modelled depth of the groundwater surface below the land surface.
