Mountain land restoration - Hautes Alpes

The map provides access to the geolocated pictures of this collection, with a navigation by municipality. For each municipality, you will find all the photographs taken in that particular area.

Access to the digitized documents

It is a selection of photographs taken in the department that is presented here. The Archives Nationales hold "merely" 1,187 photographs from a much larger collection held by the departmental archives of the Hautes-Alpes.

The collection is organised by forest conservation area around a river, a stream or main torrent, defined by the forest services, and then by series (equivalent to a municipality, a forest or a secondary branch of the main torrent) in alphabetical order within an area.

The title of the photograph generally contains a full description of the view.

    The civil engineering works described here often, but not exclusively, concern the alluvial cone, i.e. the hill formed by the deposits of the torrent as it flows into the valley. This is often where homes and infrastructure are located. These structures provide direct and immediate protection for people and their property and complement the work carried out in the reception basin.

    Since the 1860s, government departments have been working to secure natural and human habitats threatened by erosion and mountain torrents. Civil engineering and environemental engineering techniques are used to stabilise banks and reduce the slope of torrents.
