Simple download service (Atom) of the dataset: Entry points for underground cavities in Vienna

Since 2010, the State, in the Department of Vienna, has initiated a series of inventories to assess “cavitated” risk in its territory. In 2010, cavity inventories were carried out by the Bureau de Recherches Géologique et Minières (BRGM). They are based on a national methodology that allows data to be collected from the consultation of available bibliographical references as well as the questioning of all the municipalities of the department.The information concerning all the listed cavities can be found on the site: www.georisques.gouv.fr On the basis of this inventory established in 2010, more detailed inventories were carried out on a selection of municipalities. These studies, conducted by the BRGM, consist of identifying and summarising the cavities present in each communal territory and assessing the issues impacted on the surface. This work has made it possible to characterise the stakes above the voids caused by the presence of cavities. Surface issues have been identified for each entry. The areas impacted by the cavities will need special attention from the local authorities in order to best control urbanisation in under-cavated areas. In addition, other studies carried out in the context of specific procedures (e.g. development of PPRs, geotechnical studies related to development projects, etc.) provide insight into the existence of underground cavities that have not yet been inventoried. The inventories cannot be exhaustive. This table contains the entries of the underground cavities identified during the various detailed inventories and other studies carried out in the department of Vienna.
