Canalised Debris Flow Database

In order to make up a simple and user-friendly archive of all the debris flow-prone streams, a data collection from several sources (“Ufficio Bacini Montani, Prov. Autonoma di Bolzano”, “CARFRA project, Ufficio Geologia e Prove Materiali, Prov. Autonoma di Bolzano”, CORINE database, First Intervention Squad reports (FI), newspapers and others publications) was carried out for the Alto-Adige Region first (Bertotto, 2000). A standard form to be used in the setting up of the database was developed, featuring administrative characteristics, morphometry, geology and geomorphology, land use, water discharges and recorded debris flow events, particularly debris flow volumes deposited on the fan area. Thirty  streams have been inserted in the database so far, but the available data will allow to increase their number in the future.
