Harp Piemonte — BDGeo100 — Alveo types and flow rates

Alveo-type chart and maximum measured or indirectly assessed flow rates. The theme illustrates the main hive logs of the Piedmont hydrographic network, differentiated according to the characteristic environment, as well as the maximum recorded or assessed indirectly associated with a measuring point. The following were examined: frequency of floods and flow rate, slope of the river bed, quantity and particle size of the materials transported, erodibility of the banks and bottom. Cartography also shows the observation points of the peak flow rates recorded at hydrometer stations or derived from indirect measurements in significant cross-sections. 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.
