Harp Piemonte — BDGeo100 — Damage to road network

The theme illustrates the damage caused by landslides, erosive processes and flooding to the road network (road and rail) and to bridges, in Piedmont, for the period 1830-1981. The damage is distinguished according to the process that caused it and reported the number of cases established by examining the documentation available from the Technical Offices of Civil Engine, Forestry Inspectorates, Mountain Communities and Provincial and Municipal Administrations; for bridges, the extent of the damage is also reported. The dataset is part of the Geological Process Databank created in the second half of the 1980s by the Geological, Meteorological and Seismic Risk Prevention Sector of the Piedmont Region (which was then merged into the Harp) to respond to the growing demand for logical and structured information on the territory, necessary for the planning, coordination and direction of territorial-geological choices and interventions. The original thematic data was produced on I.G.M. 1:100,000 cutting by structuring and integrating the data already collected by the CNR-IRPI of Turin in the context of the research aimed at assessing the hazards associated with hydrological events in Piedmont.
