| Zusammenfassung |
| The results of an investigation on historical floods in four watersheds of
the Aude region in France are presented herein. Using both, archive documents
and field investigations, the discharges of the main historical floods could
be estimated for a period ranging from one to two centuries. The use of this
data, in addition to systematic discharge measurements (continuous series of
about 30 years in each case) shows that the calibration of Gumbel and EVII
distributions is highly modified by using historical data, despite of the
poor accuracy of discharge estimations for historical floods. In some cases,
it is also possible, with a simple test using historical data, to exclude a
statistical distribution (Gumbel in the presented case) which is not adapted
to represent both historical and systematic data samples. Lastly, the
historical data gathered highlights important differences in flood
intensities among the four studied watersheds, differences that have now to
be explained. |
