Geological model comprising artificial ground and superficial deposits in the city of Cardiff. Undifferentiated bedrock is included beneath the superficial deposits. This model provides a geological framework model and calculated surfaces for the superficial deposits for the city of Cardiff, principally Till, Glaciofluvial deposits, Alluvium and Tidal Flat Deposits.

3D geology models have been created for London, Glasgow, Cardiff, Liverpool and Gateshead. Users can create geological cross-sections, synthetic boreholes and horizontal slices through the 3D models. Underpinned by BGS geological data and expertise, the models and reports provide an enhanced understanding of the geological structures and sediments for urban practitioners to inform construction projects, infrastructure design, groundwater assessments and land use planning. These models cover depths from +300 m OD (Ordnance Datum) to -600 m OD. The models which cover Liverpool and London include superficial and bedrock units. The models which cover Glasgow and Cardiff include superficial units on an undifferentiated bedrock base model. The Gateshead Model includes undifferentiated superficial deposits on a bedrock model, but the Superficial Deposits top layer shows the hydro domains map produced for Project Groundwater Northumbria. The models were constructed in the National Geological Model, Urban Geoscience programmes and Project Groundwater Northumbria between 2008-2025 in GSI3D, Groundhog and ASPEN SKUA for deployment to the web viewer. These datasets are managed by the 3D GeoModel project (National Geoscience).

The BGS Infiltration SuDS Map is a support tool designed to support decisions on the suitability of the subsurface for infiltration SuDS; decisions on the type of infiltration SuDS that will likely be appropriate; assessments of SuDS planning applications to determine whether the necessary factors have been considered; and decisions on whether infiltration SuDS could be appropriate where a non-infiltrating SuDS technique has been proposed. This data product is not a replacement for a soakaway test or site investigation, rather a tool to support SuDS practitioners in their initial desk-based scoping of SuDS feasibility. Two versions of the data product are available: Infiltration SuDS Map: Summary and Infiltration SuDS Map: Detailed. Infiltration SuDS Map: Summary This package comprises four maps that provide an overview of ground suitability for infiltration SuDS. It does not provide any information about the properties of the subsurface. It is purely intended as a dataset for strategic planning. The Summary package consists of the following layers: - Groundwater protection summary - Infiltration constraints summary - Ground stability summary - Drainage summary Infiltration SuDS Map: Detailed This package comprises the four summary layers included within the Infiltration SuDS Map: Summary, plus an additional twenty data layers, containing a wealth of subsurface property information that can be used to make a preliminary assessment of the suitability of the subsurface for infiltration SuDS. The Detailed package consists of the following layers: - Groundwater protection summary - Groundwater source protection zones - Presence of artificial ground - Predominant groundwater flow mechanism - Infiltration constraints summary - Landslide constraints - Artificial ground constraints - Shallow groundwater constraints - Shallow mining (non-coal) constraints - Soluble rock constraints - Ground stability summary - Collabsible ground - Compressible ground - Landslides - Running sands - Shallow mining - Soluble rocks - Shrink-swell - Drainage summary - Bedrock permeability - Depth to water table - Geological indicators of flooding - Superficial deposit permeability - Superficial deposit thickness Layers are provided as GIS vectorised 50 m grids at 1:50,000 scale providing 50 m ground resolution with text descriptions and a numeric score field indicating the suitability of the ground for infiltration.
