Regione Piemonte - Historical Landslide & Floods October 2000 Dora Baltea River - Geoportale Arpa Piermonte

Data on the morphological effects induced by the flood of 13-16 / 10/2000 of the river Dora Baltea, in the stretch between Carema and the Confluence in the river Po, derived both from the surveys conducted immediately after the event (period between October 16th and on November 20, 2000), both by subsequent photointerpretative analyzes (aerial photographs taken in October 2000 were used, in the days immediately following the event, while for the stretch between Settimo Vittone and the border with the Valle d'Aosta Region aerial photos taken in October 2001 were used). Through the surveys carried out in the days immediately following the event, the flooded areas were demarcated, the traces of the flood water heights measured in the countryside were surveyed and the main damage recorded. Survey areas: the effects and damages induced by floods were detected for the stretch between the regional border between the Piedmont and the Valle d'Aosta and the confluence in the Po, corresponding to the entire basin of the Dora Baltea in Piedmont. Regarding the induced damages, (see the themes and the relative metadocumentation) the information referring to all the analyzed basins are reported in a single coverage. Part of the flood water has also reactivated an ancient drainage channel of the Dora Baltea, currently occupied by the river Ribes, subsequently merging into the Chiusella torrent and causing flooding even in areas that are part of the current river basin of the Chiusella torrent. the effects and damages induced by floods were detected for the stretch between the regional border between Piedmont and Valle d'Aosta and the confluence in Po, corresponding to the entire basin of the Dora Baltea in Piedmont.

of use: The appropriate scale of representation and use of information is 1: 10,000 or possibly lower. (1: 25.000). Moreover, in the use of these coverings, in particular those concerning the flooded areas, it must be taken into account that they mainly derive from country surveys, which, even if performed with care and accuracy along the whole stretch of observed water course, are still localized observations. Furthermore, it must be remembered that, especially in areas affected by floods with low energy, the water may leave weak traces, which tend to disappear in a very short time or may not leave it at all, so it is not excluded, for marginal areas flooded by slow currents, that the extent of the areas may have been reported here by default. THE' riverbed shaped by flood and the most evident morphological effects derive from a systematic photointerpretation study. The limits of the flooded areas were placed above all on the basis of observations of terrain, with controls through the photointerpretation, according to the topographical base used (ie the Regional Technical Map at 1: 10,000 scale).
