    Abstract

    Chalk is a critically important aquifer in Southern England and karst features can be the source of ‘unrestricted’ pathways to the ground water reservoir leading to possible sites/mechanisms for ground water contamination. Natural solution creates sinkholes and associated depressions on the surface while anthropogenic activity creates surface depressions associated with dene holes, bell pits and old surface extraction pits. This study provides a methodology for the identification of the different features with an insight into the lithological and macro-structural controls. New LiDAR and Sentinel SAR high resolution data sets are used together with recently developed geophysical techniques to provide an identification methodology and ground model.
