| Zusammenfassung |
| The Italian network of "Centri Funzionali" is now reaching operational status both in
hydro-meteorological risk forecasting and support to the decision making of
administrations that issue natural risk warning. Each centre operates for
its district of influence. In order to have a nationwide common standard the
National Civil Protection Department proposed a quantitative warning
methodology based on the definition of rainfall thresholds correlated to
historical damages. In the first phase the thresholds have been defined
using two studies that cover all Italy: the VAPI (statistics of extreme
rainfall and discharges, see reference) and the AVI (database of historical
flood and landslide events and reported damages, see reference). This work
presents one year back analysis that compares the new methodology and the
one that has been usied since 2000 by the Liguria Region Meteorological
Centre with regard to flood warning, pinpointing the performance differences
in terms of false and missed alerts. |
