| Zusammenfassung |
| A regional probabilistic model for the estimation of medium-high return period flood quantiles is presented.
The model is based on the use of theoretically derived probability distributions of annual maximum flood peaks (DDF). The general
model is called TCIF (Two-Component IF model) and encompasses two
different threshold mechanisms associated with ordinary and
extraordinary events, respectively. Based on at-site calibration
of this model for 33 gauged sites in Southern Italy, a regional
analysis is performed obtaining satisfactory results for the
estimation of flood quantiles for return periods of technical
interest, thus suggesting the use of the proposed methodology for
the application to ungauged basins. The model is validated by
using a jack-knife cross-validation technique taking all river
basins into consideration. |
