UKCP18 Climate projections and clay shrink-swell susceptibility
Shrink-swell is recognised as the most significant geohazard across Great Britain. This dataset identifies areas of shrink-swell hazard with increased potential due to changing climatic conditions based on forecasts derived from the UKCP18 climate projections. The dataset has been created at two levels of detail for RCP8.5 emissions scenario and dates up to 2070. The Basic dataset is an overview at 2Km grid resolution whilst the more detailed Premium dataset is generated at a 50m resolution. The Open versions are simplified versions of the premium versions and are shared via BGS GeoIndex. The premium versions are paid for products. UKCP18 - UK Climate Projections 2018 project RCP8.5 - A pathway where greenhouse gas emissions continue to grow unmitigated, leading to a best estimate global average temperature rise of 4.3°C by 2100. Representative Concentration Pathways (RCPs) are a method for capturing those assumptions within a set of scenarios.

Data Quality
GeoClimate combines current GB subsidence hazard susceptibility, a GB groundwater model and climate change projections, to project future subsidence hazard. Expert BGS Geological Engineers, Groundwater Geologists and GIS specialists collaborated to generate a robust methodology. The datasets utilised and combined in GeoClimate are: -BGS GeoSure shrink-swell: BGS GB dataset providing geological information on potential clay shrink-swell, providing 5 classes from Hazard Rating A (pre-dominantly non-plastic ground conditions) to Hazard Rating E (predominantly very high plasticity ground conditions) -Zooming Object Oriented Distributed Recharge (ZOODRM) model: Provides gridded daily soil moisture deficit (SMD) values for UK, based on inputted rainfall and surface values. -11 RCM UKCP09 climate models: UKCP09 medium emissions scenario was used to force the 11 Regional Climate Model simulations, providing absolute values to input into GeoClimate. The values provided are continuous daily projections from 1950 to 2099. These datasets are used to produce a GeoClimate Volume Change Potential (VCP) score, which is based on the: -A Days in Drought (DiD) value, calculated from the ZOODRM groundwater model and 11RCM projections, -Modified Plasticity Index (IP') values, extracted from the BGS GeoSure Shrink-Swell layer.
