Abstract:
|
The mitigation of debris flow (DF) risk can be achieved by the means of reliable
warning systems. At present time, operational warning systems are mostly based
on critical rainfall thresholds (CRT) derived through the elaboration of past event
records. The prediction ability of these systems strictly depends on the quality and
availability of historical data. In order to overcome these limitations, in this work
the CRT curves are derived from mathematical and numerical simulations carried
out using a coupled hydrological-stability model. The CRT curves thus obtained
are combined with rainfall nowcasts based on the observations of meteorological
radar network. A case study in central Switzerland is presented. The performances
of the proposed system are tested through a playback analysis of a past event. It
results that the use of nowcasting allows for a crucial increment of the advance
time interval. |
