A new 3D model is being developed by the British Geological Survey (BGS) to identify areas that could be sinkhole-prone in Ripon, North Yorkshire.
The model, which will be available to the public, potential developers and planners, will help better manage the issues associated with gypsum dissolution and sinkhole propagation in Ripon.
The BGS hope it will help both geologists and non-geologists understand the distribution of soluble rocks in the sub-surface, as the model will show the distribution of boreholes and can be used to target the areas of greatest geological uncertainty.
This, the BGA hopes, will facilitate more cost-effective investigation as well as better management with respect to groundwater.

British Geological Survey Vanessa Banks said: “It will be available for specifying the depth and types of ground investigation that might be required. The model will also be used to host ongoing research with respect to non-intrusive geophysical techniques to profile the sub-surface, modelling the hydrogeology of the subsurface, and classifying the ground in terms of its geotechnical properties.”
Last August a Sainsburys Local store in Ripon was evacuated after a sinkhole opened up in an alleyway behind the store.
The project started in 2017 using Natural Environment Research Council Urgency Grant funding after a sinkhole opened up in the city and has been extended using funding from the BGS’s Shallow Geohazards and Risk project/ Engineering Geology and Infrastructure programme.
Research has been undertaken collaboratively with Harrogate Borough Council, who last month said they might need to source its own liability insurance for sinkholes for a new swimming pool.
The model is currently being finalised and will be available later before 2020.
