Harp Piemonte — BDGeo100 — Minor Taxes and Conoids

Map of potentially active conoids and the frequency of mass transport phenomena related to torrential activity in minor tax collectors. The theme presents the documented cases of violent torrential activity (mass transport during flood events) in minor tributary subdivided into frequency classes (discovered in expisodes ranging from 1830 to 1981). Potentially active conoids are also exposed (identified according to the typological characterisation of the various basins obtained according to the increased availability of loose materials in the riverbed, the morphological characteristics of the torrential rods, the presence in the basin of natural reservoirs and/or glacial or nive masses, the greater or lesser propensity to instability of the slopes and the hydrological and climatic conditions of the area). 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.
