| Zusammenfassung |
On the 4 November 2011 a flash flood event hit the area of Genoa with
dramatic consequences. Such an event represents, from the meteorological and
hydrological perspective, a paradigm of flash floods in the Mediterranean
environment.
The hydro-meteorological probabilistic forecasting system for small and
medium size catchments in use at the Civil Protection Centre of Liguria
region exhibited excellent performances for the event, by predicting, 24–48 h
in advance, the potential level of risk associated with the forecast. It
greatly helped the decision makers in issuing a timely and correct alert.
In this work we present the operational outputs of the system provided
during the Liguria events and the post event hydrological modelling analysis
that has been carried out accounting also for the crowd sourcing information
and data. We discuss the benefit of the implemented probabilistic systems
for decision-making under uncertainty, highlighting how, in this case, the
multi-catchment approach used for predicting floods in small basins has been
crucial. |
