Drilling risks up to 100 m depth

Describe the distribution of geologically and/or hydrogeologically high-risk areas to be considered for the implementation of a borehole for the construction of geothermal probe installations. Risks in drilling include the distribution of karst rocks due to cavity formations, the presence of gypsum and anhydrite rocks due to their strong swelling ability at water ingress, which can lead to elevation of the surface of the terrain, and areas with artesian groundwater. Drilling risks are reported in accordance with the current state of knowledge of geological and hydrogeological conditions. The dataset provides a basis for large-scale considerations and does not replace the carrying out of detailed investigations.
