Aims and activities

This innovative alarm system aims to predict the hydrogeological phenomenon before it occurs and more in advance, thus signaling the alarm in adequate times to take actions and implement Civil Protection procedures to safeguard public safety.


The European project INADEF is an EU initiative financed by the ERDF (Interreg V-A Italy-Austria 2014-2020) and national public contributions. INADEF is a cross-border institutional collaboration between 3 Italian Partners – ARPAV, University of Padua and University of Udine – and 2 Austrian Partners – BFW and ZAMG.

Case studies

Five case studies were selected for the INADEF project in the eastern Alps and Dolomites sectors, three in Italy and two in Austria. The monitoring sites chosen in Italy are the Moscardo stream (Friuli-Venezia Giulia), the Rovina di Cancia and the Rudan stream (Veneto); those in Austria are located in Tyrol and they are the Bettelwurfmure and the Gröbentalbach.


The innovative EWS

The overall view of the system includes the following components:

  1. Local agencies providing corrected radar data;
  2. The INCA model by ZAMG, that uses the radar data along with other inputs to generate rainfall nowcasting maps;
  3. The INADEF-EWS (Early Warning System), that uses the nowcasting maps along with other input data to generate early warning maps and alerts.


The assessment of the prediction quality was carried out on the basis of events documentation between 2010 and 2020 (11 years) and the INCA post-event precipitation distribution, using several methods. In the instrumented period of the test areas, it is is assumed that all events are documented, since they have reached the observation point. Before that moment, especially smaller events may not be documented (e.g. Bettelwurfmure). Both a) the partially incomplete event documentation and b) the limited comparability of predicted precipitation (area-values of the catchments, several km²) with point information from measuring gauges make complicate to evaluate the quality assessment of the prototype.
